Answer and Research return 'Missing Authentication Token' on ydc-index.io\n\n\n## Score by category\n\n| Category | Weight | Kagi Search API | You.com APIs | Edge |\n| --- | --- | --- | --- | --- |\n| Reliability | 16% (20 this run) | 8 | 85 | You.com APIs +77 |\n| Performance | 10%, pending | pending | pending | not scored in this run |\n| Schema \u0026 documentation | 13% (16.2 this run) | 71 | 82 | You.com APIs +11 |\n| Agent ergonomics | 13% (16.2 this run) | 75 | 84 | You.com APIs +9 |\n| Security \u0026 auth | 14% (17.5 this run) | 64 | 53 | Kagi Search API +11 |\n| Payments \u0026 pricing | 10% (12.5 this run) | 20 | 88 | You.com APIs +68 |\n| Task success | 10%, pending | pending | pending | not scored in this run |\n| Maintenance \u0026 community | 7% (8.8 this run) | 41 | 82 | You.com APIs +41 |\n| Transparency \u0026 trust | 7% (8.8 this run) | 69 | 58 | Kagi Search API +11 |\n| Negative events | ≤15 | 0 | 0 | |\n| **Total** | | **48.7 · D** | **76.5 · BB** | |\n\n## Facts side by side\n\n| Fact | Kagi Search API | You.com APIs |\n| --- | --- | --- |\n| Kind | HTTP API | HTTP API |\n| Vendor | Kagi | You.com |\n| Hosted endpoint | `https://kagi.com/api/v1/search` | `https://api.you.com/v1/search` |\n| Transports | HTTP, Streamable HTTP, stdio | HTTP, Streamable HTTP, stdio |\n| Auth | API key | OAuth or key |\n| Pricing | Pay per use | Freemium |\n| Price for web search | $12 per 1,000 requests | $5 per 1,000 requests |\n| x402 | no | payer tooling only |\n| Licence | Proprietary service under the Kagi API Terms of Service.

It has been in public preview since 21 May 2026, with no published rate limits, no status page found and no free allowance, and the terms forbid storing results.\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### Kagi Search API\n\n1. Send `POST https://kagi.com/api/v1/search` with a JSON body and `Authorization: Bearer \u003ckey\u003e`, as the OpenAPI file defines. Only `query` is required\n2. Set `limit` to cap results returned. In the mixed `search` workflow the MCP tool applies the cap to each result category separately\n3. Use `extract.count` (1 to 10) only when page text is needed. Extraction is billed at the Extract rate on top of the search\n4. Do not store results. The API terms allow only the transient caching an application needs, and require deletion on termination\n5. On 429 back off before retrying. The response covers both rate limiting and an exhausted usage limit, and no `Retry-After` header is documented\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, Kagi Search API or You.com APIs?\n\nYou.com APIs scores 76.5 (BB) on agent readiness against Kagi Search API's 48.7 (D), and leads in 5 of 7 scored categories.
