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**SerpKite.** Google SERP API with an OpenAPI 3.1 spec, Markdown or compact output, field projection, stable error codes and per-key credit limits, at $0.60 to $1.00 per 1,000 on packs that don't expire. 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## 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### 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## Questions\n\n### Which is better for AI agents, Kagi Search API or SerpKite?\n\nSerpKite scores 64.8 (B) on agent readiness against Kagi Search API's 48.7 (D), and leads in 6 of 7 scored categories. Kagi Search API leads on security \u0026 auth.\n\n### Do Kagi Search API and SerpKite need an API key?\n\nBoth need an API key.\n\n### Can an agent call Kagi Search API and SerpKite without installing anything?\n\nYes.
