Verdicts

DeepSeek Search and Fetch API

Search returns up to 50 results with a model-length summary, an authority tier and optional full text, and only successful non-empty calls are billed, at $0.75 per 1,000. It opened on 17 October 2026, with 5 requests a second per account, no OpenAPI file, no free tier, and data held in the PRC under a policy that permits training.

You.com APIs

x402 and MPP on Web Search and Finance Research, with no account needed. Two API hosts. Answer and Research return 'Missing Authentication Token' on ydc-index.io.

Before you call either

DeepSeek Search and Fetch API

  1. Keep query to 128 characters and put filters in it as operators, such as site:github.com lang:en after:2026-01-01
  2. Leave need_content false and read summary first, then call Fetch on the URLs you keep
  3. Stay under 5 requests a second per account across all keys. On 408, 429 or 5xx wait and retry, since no Retry-After is documented
  4. Don't retry a Fetch 403 or 404 unchanged. The page is blocked by policy, unreachable or has no Markdown
  5. Don't send private queries or an end user's IP in localization. Data is stored in the PRC

You.com APIs

  1. For unattended runs call GET https://api.you.com/v1/search, handle the 402 and pay with x402. It's half the MPP price for search
  2. Use https://api.you.com/mcp?profile=free to try search with no key (100 queries a day)
  3. Send Answer, Research and Finance Research to api.you.com. On ydc-index.io they fail with 'Missing Authentication Token'
  4. Pass ?tools= with only the tools you need to keep the MCP tool list short
  5. With Python SDK 3.6.0 or later, pass knowledge=None, extraction=None on search unless you want highlights and knowledge cards, which are now on by default and may cost more
