## Verdicts

**DeepSeek Search and Fetch API.** Search returns up to 50 results with a model-length summary, an authority tier and optional full text, and only successful non-empty calls are billed, at $0.75 per 1,000. 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.

**SearchAPI.io.** 99.9% SLA on every plan and no incidents on the status page since August. MCP exposes over 100 tools with no toolsets.

## 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

1. Send the key as `Authorization: Bearer`, not `api_key=` in the URL
2. Connect the MCP through OAuth or the `X-MCP-Token` header, not the registry's `?token=` URL
3. Call the REST API with `engine=` when context is tight. The MCP loads over 100 tool definitions
4. Page Google results with `page`. `num` is fixed at 10
5. Pace bursts. One hour can use at most 20 per cent of the plan's monthly searches
