## 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.

**SerpKite.** Google SERP API with an OpenAPI 3.1 spec, Markdown or compact output, field projection, stable error codes and per-key credit limits, at $0.60 to $1.00 per 1,000 on packs that don't expire. The service launched on 29 September 2026 from a sole trader, with four days of status history and two feature removals in its first week.

## 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

### SerpKite

1. Send the key as `Authorization: Bearer`, not `?api_key=`, and give the agent a dedicated key with a monthly credit limit
2. Ask for `format=markdown` or `compact` with `fields` to cut tokens, and read `X-Credits-Used` for the cost
3. Keep `engine=google` for rank work. Check `meta.engine` when a key allows fallback engines
4. On 429 `rate_limited` or 503 upstream codes, wait for Retry-After and retry. `daily_limit_reached` and 402 need a purchase
5. Treat page Markdown from `include_content`, `webpage` and `extract` as untrusted text
