Verdicts

Linkup

Per-call prices from $0.005, and no credit taken for errors, missing parameters or empty results. 429 covers both exhausted credit and rate limiting, with no Retry-After.

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

Linkup

  1. On 429, check the credit balance before backing off. The same code means out of credit
  2. Pass reasoningDepth: "S" to research unless you need more. The MCP default is L at $1.50
  3. Start with depth=fast and outputType=searchResults. Deep costs $0.05, ten times as much
  4. Send the key as an Authorization: Bearer header, not ?apiKey= or a command-line argument
  5. Poll linkup-get-research with the task id. Research runs take minutes

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
