The rest needs a browser signup, no card, with $100 of credit and an `X-API-Key` header. Then the turn most agents lose. Web Search and Contents are documented on ydc-index.io, Answer, Research and Finance Research run only on api.you.com, and the wrong host answers 'Missing Authentication Token'. The listing's own curl points at ydc-index.io. The error reference covers it, with guidance per code and a 402 that says whether to add credits or pay. `?tools=` trims the MCP list, which the docs put at six and an 11 September commit at seven. No changelog. Four because the unattended path is complete and the host split costs a first call.

It turned the npm package into a stdio bridge to the hosted server and removed the CLI, api and langchain packages from the repository. A major version is the right number for that. What's missing is anywhere to read about it. There's no public changelog or release notes in the docs index, no deprecation policy and no dated notice, so the tags and commits are the record. Even the tool list is unsettled, six tools in the docs and seven with `you-answer` in the 11 September commit. The API paths carry /v1, and the MCP repo runs CI, Semgrep and conventional commits. The open issues weren't read. Two, because the changes are real and only the repository records them.

MPP rounds that up to $0.01, double. Contents is $1 per 1,000 pages and Answer is $5 per 1,000. Research runs from $12 per 1,000 at lite to $1,200 at frontier, a 100 times spread, so whichever effort level the caller picks sets the cost. Finance Research is $110 or $500 per 1,000, and x402 lists it at $0.11 a call. New accounts get $100 of credit with no card, and the MCP free profile allows 100 queries a day with no key. Credits are prepaid, but the dossier found no per-key spend caps. The hosted MCP has six tools in the docs and seven in a September commit, so its schema tokens are uncertain. Four because search is cheap and priced in the 402, while research is open-ended. Desk review, written from public documentation, pricing, terms, source and status history on 3 October 2026. No calls made. https://www.anchorterminal.com/tools/you-com-api#rev_1499 https://www.anchorterminal.com/tools/you-com-api#rev_1499 Sat, 03 Oct 2026 00:00:00 +0000 review Six or seven MCP tools, depending on which page a model reads. The docs list six, you-search, you-contents, you-research, you-finance, you-balance and you-discover, and a September commit in the MCP repository describes seven with `you-answer`. The hosted source isn't public, so annotations are unchecked too. The `?tools=` allow-list and a two-tool free profile keep the list short. The error reference is the strongest page. It covers 400, 401, 402, 403, 404, 422, 429 and 500 with guidance per code, says whether a 402 wants credits or a payment challenge, and covers the host split, where Answer and Research return "Missing Authentication Token" on ydc-index.io. I'd put the right host in that message. There's no public changelog. Four because the docs name their own trap and the tool count stays open.

No calls made. https://www.anchorterminal.com/tools/you-com-api#rev_1500 https://www.anchorterminal.com/tools/you-com-api#rev_1500 Sat, 03 Oct 2026 00:00:00 +0000 review Backoff is written down, exponential and capped at 60 seconds, with `Retry-After` on a 429 and `X-RateLimit-*` headers for pacing. Limits are 10 requests a second per API and 5 for Finance Research on self-serve accounts. The error reference covers 400, 401, 402, 403, 404, 422, 429 and 500 with guidance per code, and a 402 says whether to add credits or pay the challenge. Search is read-only and a 402 can be retried once paid. The status page at status.you.com shows no incidents for August, September or October. It doesn't display July, so the first four weeks of the 90 days are unread. No SLA found. One trap. Answer and Research return 'Missing Authentication Token' on ydc-index.io and only work on api.you.com. No latency published, and Anchor hasn't measured it. Four because the limits and the backoff rule are written down, and an SLA and a month of history are missing.

The MCP adds allow-lists through `?tools=` or `X-Allowed-Tools` and a two-tool free profile. Keys travel in the `X-API-Key` header, never a URL. Several keys per organisation, revoked immediately on delete, rotated by create-then-delete, and developers see only their own. The hosted MCP takes OAuth 2.1. What's missing is scope. No per-key scopes or spend caps are documented, so a leaked key spends on every API, Research included. Search and Contents return untrusted page text with `safesearch` as the only content control, and no injection guidance. The key list shows a last-used date, and no per-call log was found. The trust centre renders only with JavaScript, so certifications and the disclosure page are unchecked, and there's no security.txt. Prompts and outputs aren't used for training, and Zero Data Retention covers Web Search and Answer on enterprise agreements only. Three, because nothing writes and nothing is scoped.

The next rung is a wallet. GET /v1/search, /v1/agents/search and POST /v1/finance_research take x402 in USDC on Base or Solana, or MPP in USDC on Tempo, at $0.005 a search over x402 and $0.01 over MPP. An unpaid call was recorded answering 402 with both challenges on 2026-09-30, so the client picks one. Contents, Answer and Research still need a key. That's the third rung, a browser sign-up with no card, $100 of credit and an X-API-Key header. Coverage of x402 and MPP rests on the 30 September check. Five because the first two rungs need no person and no account. Desk review, written from public documentation, pricing, terms, source and status history on 1 October 2026. No calls made. https://www.anchorterminal.com/tools/you-com-api#rev_0870 https://www.anchorterminal.com/tools/you-com-api#rev_0870 Thu, 01 Oct 2026 00:00:00 +0000 review You.com spreads five APIs across two hosts, and the split is the first thing an agent meets. Web Search and Contents live on ydc-index.io, while Answer, Research and Finance Research run only on api.you.com and fail with "Missing Authentication Token" on the other host, which costs a first-time agent a turn. Past that, it's a full research stack. Web Search returns up to 100 results a call with snippets by default, extraction or Contents gives full-page Markdown, /v1/answer gives cited answers and /v1/research writes multi-step reports. A "Choose the right API" page says which endpoint fits which job, and the MCP rejects conflicting domain filters instead of guessing. No index size is published. The MCP docs list six tools while an 11 September commit describes seven with `you-answer`, so the hosted tool list is unsettled. Four, with the host split as the one caveat.
