Verdicts

Cloudflare Web Search API

One endpoint that sends a search to Ceramic.ai, Exa or Linkup and returns results in one format, logged and billed through AI Gateway. Ceramic.ai costs $0.25 per 1,000 searches. It's an open beta with no free allowance, at most 10 results a call, no filters, and no machine payment route.

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.

Before you call either

Cloudflare Web Search API

  1. Set options.gateway.id. Every account has a gateway named default
  2. Pass provider explicitly. It defaults to Ceramic.ai, whose descriptions can run to 8,000 characters a result
  3. Set limit to the results you'll read, between 1 and 10
  4. Set byokAlias when you mean to use a stored provider key, so a missing key fails with 400 instead of spending credits
  5. Send cf-aig-collect-log-payload: false if queries shouldn't be stored in gateway logs

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
