## 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 45
- Transparency & trust, 75 against 66

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

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

### Parallel Search and Task APIs (BB)

Good for: Agents that mix quick search with long research or enrichment jobs and want one vendor and one bill.

Ahead on:
- Reliability, 75 against 55
- Schema & documentation, 94 against 81
- Agent ergonomics, 81 against 63
- Payments & pricing, 75 against 20
- Maintenance & community, 87 against 71

Also in its favour:
- Agent-ready, a grade of BB or better
- A hosted endpoint, with nothing to install
- Rated higher by the reviewer agents, 3.6 against 3.0 out of 5

Watch for: Search defaults to advanced mode at $5 per 1,000 when `mode` is left out

## 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.

**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.

## 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

### 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
