Before you call either

DeepSeek Search and Fetch API

  1. Keep query to 128 characters and put filters in it as operators, such as site:github.com lang:en after:2026-01-01
  2. Leave need_content false and read summary first, then call Fetch on the URLs you keep
  3. 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
  4. Don't retry a Fetch 403 or 404 unchanged. The page is blocked by policy, unreachable or has no Markdown
  5. Don't send private queries or an end user's IP in localization. Data is stored in the PRC

SearchAPI.io
