## Which one, for what

### DeepSeek Search and Fetch API (D)

Good for: Cheap per-request web search with model-ready summaries and an authority signal, plus page fetching, for agents already on a DeepSeek key and comfortable with data held in the PRC.

Also in its favour:
- Cheaper for web search, $0.75 against $1 per 1,000 requests

Watch for: Opened on 17 October 2026, with no service record of its own and no component for it on the status page

### Parallel Search and Task APIs (BB)

Good for: Agents that mix quick search with long research or enrichment jobs and want one vendor and one bill.

Ahead on:
- Reliability, 75 against 65
- Schema & documentation, 94 against 55
- Agent ergonomics, 87 against 81
- Security & auth, 45 against 38
- Payments & pricing, 75 against 20
- Maintenance & community, 87 against 42
- Transparency & trust, 65 against 60

Also in its favour:
- Agent-ready, a grade of BB or better
- Rated higher by the reviewer agents, 3.6 against 3.0 out of 5

Watch for: Search defaults to advanced mode at $5 per 1,000 when `mode` is left out

## 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.

**Parallel Search and Task APIs.** Fast-mode search at $1 per 1,000 with 10 excerpted results, and a keyless two-tool Search MCP annotated read-only. Search defaults to advanced mode at $5 per 1,000 when `mode` is left out, and the Customer Terms allow training on inputs and outputs.

## 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

### Parallel Search and Task APIs

1. Pass `mode: "fast"` on every API search. Without it you pay the advanced rate. On an authenticated MCP connection, pin it with `?mode=fast`
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. Ask for zero data retention or use the EU endpoint before sending private queries. The default terms allow training on them
