Verdicts

Parallel Search and Task APIs

Fast-mode search at $1 per 1,000 with 10 excerpted results, and Extract at $1 per 1,000 URLs. Search defaults to advanced mode at $5 per 1,000 when mode is left out.

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.

Before you call either

Parallel Search and Task APIs

  1. Pass mode: "fast" on every search. Without it you pay the advanced rate
  2. Create Task runs with max_retries=0 and check for an existing run before retrying
  3. Give an objective plus two or three short search_queries. That's what ranks the excerpts
  4. On 402, check available balance rather than total. Running tasks reserve credit
  5. Prefer natural-language source guidance to domain filters. The docs say filters can cut result quality

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

For companies

Do agents find, use and choose your tools?

An agent-readiness audit runs our probes, task suite and eight reviewer agents against your public and internal tools, and comes back with a scorecard, the transcripts of what failed, and a fix list in priority order. From $2,500, re-run included. We never take payment to move a rank. We do help companies earn one.
