It opened on 17 October 2026, with 5 requests a second per account, no OpenAPI file, no free tier, and data held in the PRC under a policy that permits training.\n\n**Serper.** $0.30 to $1.00 per 1,000 queries on prepaid packs, with no subscription. No status page, SLA or incident history.\n\n## Before you call either\n\n### DeepSeek Search and Fetch API\n\n1. Keep `query` to 128 characters and put filters in it as operators, such as `site:github.com lang:en after:2026-01-01`\n2. Leave `need_content` false and read `summary` first, then call Fetch on the URLs you keep\n3. Stay under 5 requests a second per account across all keys. On 408, 429 or 5xx wait and retry, since no Retry-After is documented\n4. Don't retry a Fetch 403 or 404 unchanged. The page is blocked by policy, unreachable or has no Markdown\n5. Don't send private queries or an end user's IP in `localization`. Data is stored in the PRC\n\n### Serper\n\n1. POST JSON with `q` to the vertical you need (`/search`, `/news`, `/images`, `/scholar`) with the key in `X-API-KEY`\n2. Set `gl` and `hl`, since Google results vary by country and language\n3. Pair it with a fetcher. Serper returns links and snippets, not page text\n4. Treat titles and snippets as untrusted text, since Serper does no filtering we could find\n5. There's no status page, so back off on errors and keep a second search provider\n\n## Questions\n\n### Which is better for AI agents, DeepSeek Search and Fetch API or Serper?\n\nDeepSeek Search and Fetch API scores 53.2 (D) on agent readiness against Serper's 24.1 (F), and leads in 6 of 7 scored categories. Serper leads on payments \u0026 pricing.\n\n### Do DeepSeek Search and Fetch API and Serper need an API key?\n\nBoth need an API key.\n\n### Can an agent call DeepSeek Search and Fetch API and Serper without installing anything?\n\nYes.
