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
