## Which one, for what

### Cloudflare Web Search API (B)

Also in its favour:
- No incidents deducted, where SerpKite loses 3 points for them

- Agent ergonomics, 92 against 63
- Payments & pricing, 40 against 20

## 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.

**SerpKite.** Google SERP API with an OpenAPI 3.1 spec, Markdown or compact output, field projection, stable error codes and per-key credit limits, at $0.60 to $1.00 per 1,000 on packs that don't expire. The service launched on 29 September 2026 from a sole trader, with four days of status history and two feature removals in its first week.

## 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

### SerpKite

1. Send the key as `Authorization: Bearer`, not `?api_key=`, and give the agent a dedicated key with a monthly credit limit
2. Ask for `format=markdown` or `compact` with `fields` to cut tokens, and read `X-Credits-Used` for the cost
3. Keep `engine=google` for rank work. Check `meta.engine` when a key allows fallback engines
4. On 429 `rate_limited` or 503 upstream codes, wait for Retry-After and retry. `daily_limit_reached` and 402 need a purchase
5. Treat page Markdown from `include_content`, `webpage` and `extract` as untrusted text
