## 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 $7.50 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

### Tavily API + MCP (BB)

Good for: An agent that needs search plus page text in one call and has no account yet.

Ahead on:
- Reliability, 90 against 65
- Schema & documentation, 89 against 55
- Security & auth, 52 against 38
- Payments & pricing, 75 against 20
- Maintenance & community, 85 against 42

Also in its favour:
- Agent-ready, a grade of BB or better
- Runs on your own machine
- Free to start without a card
- Open source
- Rated higher by the reviewer agents, 3.6 against 3.0 out of 5

Watch for: x402 covers advanced search only, not extract, map, crawl or research

## 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.

**Tavily API + MCP.** Keyless search and extract, plus a free 1,000 credits a month with no card. x402 covers advanced search only, not extract, map, crawl or research.

## 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

### Tavily API + MCP

1. Try `X-Tavily-Access-Mode: keyless` first for search and extract. Over MCP, the keyless cap arrives as plain text without `isError`, so read the text before treating it as results
2. Send the key in `Authorization: Bearer`, not `?tavilyApiKey=` in the MCP URL
3. On 429, wait for `Retry-After`. A 432 or 433 means a spend limit, and retrying won't help
4. Run /map before /crawl to bound the crawl, since crawl is billed as map plus extract
5. Research is async and runs 4 to 250 credits. Create the task, then poll /research/{request_id}
