Verdicts

SearchAPI.io

99.9% SLA on every plan and no incidents on the status page since August. MCP exposes over 100 tools with no toolsets.

Valyu

Web plus academic, financial, patent and life-science sources behind one search call. No published rate limits and no Retry-After or backoff guidance.

Before you call either

SearchAPI.io

  1. Send the key as Authorization: Bearer, not api_key= in the URL
  2. Connect the MCP through OAuth or the X-MCP-Token header, not the registry's ?token= URL
  3. Call the REST API with engine= when context is tight. The MCP loads over 100 tool definitions
  4. Page Google results with page. num is fixed at 10
  5. Pace bursts. One hour can use at most 20 per cent of the plan's monthly searches

Valyu

  1. Set max_price and max_num_results on every search to bound cost
  2. Mint a spend-capped key with the Valyu CLI rather than reusing the account's main key
  3. Call valyu_search. The legacy per-vertical MCP tools stop working on 2026-12-01
  4. A 206 means some sources failed. Check which before treating results as complete
  5. DeepResearch is async. Poll valyu_deepresearch_status rather than waiting in one call
