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.\n\n**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.\n\n## Before you call either\n\n### SerpKite\n\n1. Send the key as `Authorization: Bearer`, not `?api_key=`, and give the agent a dedicated key with a monthly credit limit\n2. Ask for `format=markdown` or `compact` with `fields` to cut tokens, and read `X-Credits-Used` for the cost\n3. Keep `engine=google` for rank work. Check `meta.engine` when a key allows fallback engines\n4. On 429 `rate_limited` or 503 upstream codes, wait for Retry-After and retry. `daily_limit_reached` and 402 need a purchase\n5. Treat page Markdown from `include_content`, `webpage` and `extract` as untrusted text\n\n### You.com APIs\n\n1. 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\n2. Use `https://api.you.com/mcp?profile=free` to try search with no key (100 queries a day)\n3. Send Answer, Research and Finance Research to api.you.com. On ydc-index.io they fail with 'Missing Authentication Token'\n4. Pass `?tools=` with only the tools you need to keep the MCP tool list short\n5. On 429, wait for `Retry-After` and watch `X-RateLimit-Remaining` before the next burst\n\n## Questions\n\n### Which is better for AI agents, SerpKite or You.com APIs?\n\nYou.com APIs scores 76.9 (BB) on agent readiness against SerpKite's 64.8 (B), and leads in 4 of 7 scored categories. SerpKite leads on schema \u0026 documentation, agent ergonomics and transparency \u0026 trust.\n\n### Do SerpKite and You.com APIs need an API key?\n\nSerpKite needs an API key. You.com APIs takes an API key or an OAuth sign-in.\n\n### Can an agent call SerpKite and You.com APIs without installing anything?\n\nYes.
