Verdicts

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.

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

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

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
