## Which one, for what

### Cloudflare Web Search API (B)

Good for: Agents and apps already on Cloudflare Workers or AI Gateway that want cheap snippet search ($0.25 per 1,000 with Ceramic.ai) on the same bill and logs as their inference.

Ahead on:
- Security & auth, 71 against 52
- Transparency & trust, 75 against 65

Also in its favour:
- Cheaper for web search, $0.25 against $7.50 per 1,000 requests

Watch for: Open beta, with no SLA found for AI Gateway

### Tavily API + MCP (BB)

Good for: An agent that needs search plus page text in one call and has no account yet.

Ahead on:
- Reliability, 90 against 55
- Schema & documentation, 89 against 81
- Agent ergonomics, 81 against 63
- Payments & pricing, 75 against 20
- Maintenance & community, 85 against 71

Also in its favour:
- Agent-ready, a grade of BB or better
- A hosted endpoint, with nothing to install
- Runs on your own machine
- Free to start without a card
- Open source

Watch for: x402 covers advanced search only, not extract, map, crawl or research

## 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.

**Tavily API + MCP.** Keyless search and extract, plus a free 1,000 credits a month with no card. x402 covers advanced search only, not extract, map, crawl or research.

## 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

### Tavily API + MCP

1. Try `X-Tavily-Access-Mode: keyless` first for search and extract. Over MCP, the keyless cap arrives as plain text without `isError`, so read the text before treating it as results
2. Send the key in `Authorization: Bearer`, not `?tavilyApiKey=` in the MCP URL
3. On 429, wait for `Retry-After`. A 432 or 433 means a spend limit, and retrying won't help
4. Run /map before /crawl to bound the crawl, since crawl is billed as map plus extract
5. Research is async and runs 4 to 250 credits. Create the task, then poll /research/{request_id}
