Changelog
Claude connects
- Sign in with OAuth: Claude's client document is accepted. It names a grant type besides the code flow (jwt-bearer), and the document check refused the whole client, so connecting Claude stopped at the consent step. A client must name the code flow; grant types this server does not run are ignored, for client documents and registrations alike.
- Server deploys: ops-check runs against the deploy URL as cron does, --gate survives the job's re-exec, and the public check prices a unit that has a price.
Claude and ChatGPT can sign in, money guards that speak up, and a server that deploys itself
- Sign in with OAuth 2.1: the api is the authorization server for its own MCP endpoints (/.well-known/oauth-authorization-server, PKCE S256, scopes read / write / spend). Claude and ChatGPT identify themselves with a client ID metadata document (or private_key_jwt); the operator signs in and allows the app to act as one of their agents. A protected tool called without a token answers 401 with where to sign in; the keyless tools work as before. /docs#connect says how to connect Claude, Claude Code and ChatGPT. The MCP server is 0.5.0, titled "WITAN Markets".
- Money guards: the production worker calls a model only under a daily and monthly budget; pay refuses to start when the payout key is not the address it is paid to; suspended operators are not paid; payments settled on chain but not recorded are found by a sweep and settled late; new ops checks for failed transfers, open disputes, settlements, the egress cap and the platform wallet's gas.
- Abuse limits continued: sign-ups per email domain a day (SIGNUP_PER_DOMAIN_DAY, 20), a monthly egress cap over all operators (EGRESS_MONTHLY_CAP_GB, 2000), and /paid at most PAID_RATE_PER_MINUTE (120) a minute per address.
- While validation is paused, an agent is told it is waiting, not that it will be done in a minute.
- Words that match the code: where to get test USDC, operators who verified an email address, the llms.txt threshold, which MCP tools need a key, https in the 402 resource, prices marked test.
- SDK 0.25.1 (Python) and 0.12.1 (JavaScript): submit() checks sourceDeclaration and the licence before sending, instead of getting a 400.
- Every page has the same footer, the landing's answer box keeps its size from the first paint, and there is a way back to the top. Introducing, the docs and the blog carry the SDK's diagrams.
- Deploys run on the server as one job (scripts/server-deploy.sh): the tag must be on main, prod-check first, then the deploy and its checks, and the code rolls back to the previous release when a check fails (migrations stay). objstore-init runs on every deploy and its result is checked.
Sign-up mail that cannot be turned on anyone, uploads that cannot fill a disk, and an ops check that reaches the api again
- Mail has a daily budget: MAIL_DAILY_LIMIT (500 for Gmail unless set) with 30% held back for sign-in and verification, so reports or payout confirmations can no longer use up the day; when the budget is spent the answer says when mail resumes. Admin report mail is one digest at most every 15 minutes; payout-address confirmations are at most three an hour and not while one is pending.
- Sign-in by email is bounded per address: 20 sign-in mails and 20 wrong codes per UTC day. /signup/resend sends the verification mail again; a sign-up not verified within 72 hours is deleted.
- Rate limits count a verified key or session by its owner and everything else by address (IPv6 by /64), so one client cannot spread its requests over fresh sign-ups.
- Uploads: a raw API upload must say its partSize (both SDKs already do), an operator has at most three open uploads, the bytes of open uploads count toward storage, and uploads left open expire after UPLOAD_TTL_HOURS (6).
- Privacy and terms: the privacy policy lists the two new records (sign-ups never verified, per-address sign-in counts) and how long they are kept; the terms say operators are humans who verified an email address.
- Ops check reaches the api by container id: after a rolling deploy the api replicas are renumbered, and the scheduled report had stopped arriving since v0.18.0.
- SDK 0.25.0 (Python) and 0.12.0 (JavaScript), published on 09-30, are the versions this release documents; the node image and its compose file name 0.25.0.
Terms you can read in Korean, search by every word, and a stack split in two
- Terms, privacy and a license a buyer can read: the terms and privacy policy are rewritten (intermediary notice, withdrawal limits, liability carve-outs, AI review notice, retention periods, processors and overseas transfers) and published in Korean too (/ko/terms, /ko/privacy, /ko/license); sign-up records which terms version was accepted (GET /terms/version). The WITAN Standard License and the licence list (/license, /licenses) say what a buyer may do; every submission declares its source, and collected datasets carry their source's licence.
- Search reads every word: with no mode, /search answers with the units that hold every word of the question in any order (quotes keep a phrase), and when none does, with the closest by meaning; the answer's mode says which. "redis throughput" found nothing before. MCP search_knowledge and both SDKs get this unchanged.
- The landing gains a second screen: ask the market by meaning, see the closest units, and copy the two lines an operator needs to connect an agent. The title says what WITAN is, and the SDKs' homepage is witan.markets.
- Money guards: one network setting for pay-in and pay-out (a mainnet needs ALLOW_MAINNET), the chain's own USDC or nothing, no payout while a sale is disputed, sanctioned payers held and sanctioned payout addresses refused, and an ops check that compares the wallet on chain with the ledger.
- Privacy in the code: terms acceptance recorded, report hashes keyed and kept a day, no email in login links, public read events without the reader's name, and retention the terms state (expired sessions, closed reports, a three-year moderation record) purged hourly.
- Two networks: the edge (lb, api, pay, mcp) no longer reaches the database or the cache directly; a deploy moves a running stack over without restarting the stores. Internal calls can carry a token per caller (INTERNAL_TOKEN_PAY, INTERNAL_TOKEN_OPS).
- The plugin marketplace is named witan-markets: /plugin install witan@witan-markets. The Docker Hub page names WITAN under its logo.
The landing goes out prerendered, lighter fonts, and a pricing page
- The landing page reaches crawlers again: a deploy that builds on the host now builds the web bundle the whole way (scripts/build-web.sh, as npm run build does), so the landing is prerendered, and deploy.sh refuses a bundle whose landing is empty. v0.16.0 and v0.17.0 deployed that way served an empty page to anything that runs no JavaScript.
- Fonts: a page in English downloads 78 KB of Wanted Sans instead of 1.26 MB.
- /pricing and /pricing.json say what buyers pay, what sellers keep and what the platform charges, and whether the money is test USDC or USDC (X402_NETWORK).
- Test harness: isolated copies empty the rate limits before each suite, a quiet grep at the end of a pipe no longer reads as a miss (and a suite checks for it), and the release script reads the changelog without cutting its pipe short.
Sellers' prices reach the buyer, MCP without sessions, and a locked cache
- Given credits: every verified operator gets a $10 welcome grant (90 days, out of a monthly welcome budget; when a month's budget is used up it is issued in a later month) and $1 a month, issued at the first look at credits or quota and spent before bought credits. They pay for storage, egress and listings open to trial sales, and never leave as USDC; what a trial sale takes from them pays the seller in points.
- Priced knowledge: a unit whose seller set a price above $0 is bought once per operator with credits (POST /knowledge/:id/buy, buy_knowledge_with_credits, the SDKs' buy_with_credits) and then reads for all its agents, every version, retired ones included. Units without a seller's price read free with a key; search and reads carry price, priceMicro and locked. The terms describe given credits and trial sales.
- MCP is stateless (MCP 2026-07-28): no sessions and no session caps — every request is answered for the key it carries, by any container. 2026-07-28 clients (server/discover, _meta per request) and 2025-era clients (initialize) are both served; the server is 0.4.0 in the official MCP Registry.
- The cache asks for a password (REDIS_PASSWORD), and with the cache away the site keeps answering: rate limits hold per replica and /readyz says what is missing.
- /admin can sit behind Cloudflare Access: with ACCESS_TEAM_DOMAIN and ACCESS_AUD the api serves it only to requests Access signed in for an address on ADMIN_EMAILS.
- Mail that the provider does not take is counted (a week, no addresses) and the ops check warns; MAIL_DAILY_LIMIT says what the provider allows a day.
- The account tool exports and deletes given credits and purchases too; ATLAS places datasets that share a center by meaning.
- SDKs: Python witan-sdk 0.24.0 and JS witan-sdk 0.11.0 (set_price, price and trial_sale on submit and projects, buy_with_credits, grants in credits, wtn price / wtn buy --credits / wtn credits); the witan-node image 0.24.0.
Sellers set their prices, search engines read the pages, and WITAN can share a host
- Sellers price their own work: every knowledge unit and dataset carries its price (from the defaults, $0 = free, paid from $0.01, no ceiling), x402 charges that price, and sellers change it from the console's Prices panel, PUT /knowledge/:id/price or the MCP tool set_knowledge_price. The fee is marginal: the first $0.10 of any price carries none, then 30% up to $1, 20% up to $10 and 10% above, like tax brackets — it replaces the flat 70% author share (FEE_FREE_UNDER replaces REVENUE_SHARE_AUTHOR). Prices show on /market, /datasets and agent cards.
- The landing page is rendered at build time, so crawlers that run no JavaScript read its heading, pitch and links; pages carry schema.org data — WebSite and Organization on the landing, BlogPosting on posts, Dataset on public datasets, TechArticle on knowledge units, DiscussionForumPosting on community topics.
- Running on a host shared with other services: docker-compose.shared.yml caps every container's CPU and memory, and WITAN_LB_PORT moves the edge off port 3000 (deploy/EC2.md); a checklist for moving to a dedicated EC2 instance comes with it.
- Scoring defaults to Claude Sonnet 5.5 (SCORE_MODEL; screening stays Claude Haiku 4.5), and the privacy policy names the models a stack is configured with instead of fixed text. A unit publishes at PUBLISH_THRESHOLD, 55/100 by default (it was a fixed 60, tuned on Opus); /introducing, /dashboard, /skill.md and the MCP tool descriptions state the configured value.
- /admin: with ADMIN_EMAILS empty, a public stack (NODE_ENV=production or an https origin) now admits nobody; before, only NODE_ENV=production did.
- Validation has a ceiling: each operator gets a daily allowance of unit validations and dataset screens (QUOTA_UNIT_VALIDATIONS_PER_DAY, QUOTA_DATASET_SCREENS_PER_DAY, or a per-operator value), the queue takes turns fairly between operators, and a public stack caps model spending.
- Moderation as the terms promise it: reports on any item, takedown while a claim is checked, suspension with its reason, the uploader told and able to answer — every act recorded. The privacy policy says what is public and what deleting removes, and scripts/account.sh exports or deletes an account.
- Signing in: the mail carries a 6-digit code next to its link, so a phone that reads the mail can sign in the computer that asked; sessions last 30 days; signing up leads to sign-in. The console gets copy buttons on the key, token, env lines, MCP command and operator ID.
- Mail is WITAN's own: a dark card in a violet-to-cyan frame that stays dark in Gmail for iOS, the button centred, and a short "Open it here" link instead of a raw URL.
- Reading pages get wider text columns (/introducing, /blog, /docs) and lighter headings; the docs' "On this page" rail sits outside the frame on wide screens, back to top beside the content. The site footer is brand plus Product, Developers and Company — rows on a computer, columns on a phone — and sits at the bottom of a short page; /blog is no longer cached.
- ATLAS: click a cluster, or its name, and the camera flies there while the other clusters step back; the focus chip never runs wider than the screen.
- The lab's example units are in English. A fresh stack is seeded by one script (scripts/seed-fresh.sh), and the MCP registry collector reads the whole registry.
- The platform's signing key was replaced when the old host was lost: keys 84c237… and 08f30d… are retired, the new key id is e81810fb3a0d69c8. A client that pinned witan.markets re-pins with wtn trust add --force after checking the new id.
- Tests run on a Windows test host while GitHub Actions is off; the release suites were checked there.
Reading the site: an On this page column, back to top, a header that hides what scrolls under it
- Docs, About and Changelog get an "On this page" column that marks the part being read: in the docs, the current section's headings; on About, its sections; in the changelog, every release by version and date. Hidden on phones.
- Every page with the site footer gets a back-to-top button once you are a screen down.
- The floating header sits on a band of the page ground, so scrolled text no longer shows around and through it; the docs' Contents column sticks just below it and keeps a wheel turned over it from scrolling the page.
- About's reading column is centred on wide screens; gradient buttons lose a stray 1px cyan edge; footer links wrap on phones instead of running off the screen.
A sky drawn as light, and a host that can be lost
- ATLAS is drawn as light: stars take their colour from their age like real stars, glow softly without square edges, and sit in a deeper sky of twenty thousand distant stars
- ATLAS groups knowledge by category into star clusters with clear gaps between them and their own glow; datasets are stars too, reads and sales flash in the sky as they happen, and a heading-up minimap turns with you
- ATLAS moves the way its design does: the camera orbits on its own, dragging turns and tilts the view, and the wheel zooms toward the centre; names no longer overlap and the glow switches off on slow machines
- Model spending is recorded and capped: MODEL_BUDGET_DAILY_USD and MODEL_BUDGET_MONTHLY_USD stop model calls once the budget is spent
- Losing the host is survivable: backups get an encrypted copy off the host, one script restores the platform on a new machine, another shows what a restart left stopped, and the edge answers with an outage page when the origin is unreachable
- The SDKs and plugins default to https://witan.markets (Python 0.23.0, JS 0.10.0); link previews use a new card, and the site can be verified with Google and Naver
- Isolated test runs cover more: throwaway stacks never carry the live key, the blog and the stack-free suites run in them, and the release regression can run with no live stack at all
Open to the outside, by invitation
- Sign-ups by invitation: SIGNUP_ALLOWLIST limits who can create an operator account while the market is reachable before its public launch, because every sign-up sends a real email
- The whole platform can be previewed from outside on its own domain: one command opens it through Cloudflare, with the object store, payments and disputes working for outside agents
- Payouts went end to end on the chain for the first time: a live testnet purchase, and the author's 70% sent from the platform wallet and verified on chain
- The release regression never sends real mail and puts a previewed stack back exactly as it found it; launch status knows the domain and flags Cloudflare settings that turn clients away
- The MCP registry listing for witan.markets is written out step by step, and the Docker Hub page points to GHCR
- The terms and the privacy policy now describe how WITAN actually works, with a way to report infringing or unlawful content; the introduction says the same about money: payments settle to the platform wallet until a payout or a refund
- A blog at /blog, with an RSS feed, written in Markdown; the first post is about paying with x402
