## 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:
- Reliability, 55 against 30
- Schema & documentation, 81 against 6
- Agent ergonomics, 63 against 35
- Security & auth, 71 against 20
- Maintenance & community, 71 against 3
- Transparency & trust, 75 against 33

Also in its favour:

### Serper (F)

Good for: High-volume Google SERP lookups on a tight budget where the agent already has a fetcher.

Ahead on:
- Payments & pricing, 40 against 20

Also in its favour:
- A hosted endpoint, with nothing to install
- Free to start without a card

Watch for: No status page, SLA or incident history

## 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.

**Serper.** $0.30 to $1.00 per 1,000 queries on prepaid packs, with no subscription. No status page, SLA or incident history.

## 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

### Serper

1. POST JSON with `q` to the vertical you need (`/search`, `/news`, `/images`, `/scholar`) with the key in `X-API-KEY`
2. Set `gl` and `hl`, since Google results vary by country and language
3. Pair it with a fetcher. Serper returns links and snippets, not page text
4. Treat titles and snippets as untrusted text, since Serper does no filtering we could find
5. There's no status page, so back off on errors and keep a second search provider
