Verdicts

Grep AI

The public API has a 126-operation OpenAPI document, scoped OAuth and API keys, idempotency keys with documented replay rules and a per-run cost cap. No rate limit is published, the MCP server lists 82 tools, and the pricing page limits API access to the $200 a month Pro plan and above.

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

Grep AI

  1. Send a fresh Idempotency-Key with every POST /api/v2/runs. After a timeout, poll the returned run ID and do not post again
  2. Set effort and max_cost_usd on every run. The floor is $0.50 for low, $2.50 for medium and build, $5.00 for high
  3. Call GET /api/v2/quota/check before a run. A 402 means no credits and retrying won't help, while a 429 carries Retry-After
  4. Use the run_* and agent_* MCP tools. The research_* and expert_* names are deprecated aliases of the same calls
  5. Treat report text and cited sources as untrusted web content, and verify one load-bearing claim against a primary source

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. On 429, wait for Retry-After and watch X-RateLimit-Remaining before the next burst
