## Verdicts

**Parallel Search and Task APIs.** Fast-mode search at $1 per 1,000 with 10 excerpted results, and Extract at $1 per 1,000 URLs. Search defaults to advanced mode at $5 per 1,000 when `mode` is left out.

**You.com APIs.** x402 and MPP on Web Search and Finance Research, with no account needed. Two API hosts. Answer and Research return 'Missing Authentication Token' on ydc-index.io.

## Before you call either

### Parallel Search and Task APIs

1. Pass `mode: "fast"` on every search. Without it you pay the advanced rate
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. Prefer natural-language source guidance to domain filters. The docs say filters can cut result quality

### You.com APIs

1. For unattended runs call GET https://api.you.com/v1/search, handle the 402 and pay with x402. It's half the MPP price for search
2. Use `https://api.you.com/mcp?profile=free` to try search with no key (100 queries a day)
3. Send Answer, Research and Finance Research to api.you.com. On ydc-index.io they fail with 'Missing Authentication Token'
4. Pass `?tools=` with only the tools you need to keep the MCP tool list short
5. On 429, wait for `Retry-After` and watch `X-RateLimit-Remaining` before the next burst
