Changelog

Breaking and notable changes to the Caicaini API surface. Newest at the top. Watch this page if you depend on the API in production.

Versioning

The API is in v0.x. We are explicit about which fields are stable and which are not. Breaking changes will be announced here at least 30 days in advance once we ship v1.0; until then, expect occasional schema additions (always non-breaking) and rare schema renames (always announced).

    Public Developer API live

    The Caicaini Developer API is live in beta. Two compatible HTTP surfaces are available:

    • POST /v1/messages with non-stream and SSE streaming.
    • POST /v1/chat/completions with non-stream and SSE streaming.
    • POST /v1/messages/count_tokens for input-token previews.
    • GET /v1/models, GET /v1/account, GET /v1/usage.

    Five virtual model ids ship: caicaini/auto, caicaini/opus, caicaini/sonnet, caicaini/kimi, caicaini/haiku. Native vision, tool use, and extended thinking are supported on the models documented in their respective pages.

    Top-up packs ($10 → $1,000) and a custom-amount slider ($10 – $10,000) are live on /developers/billing. Top-up credits land in a dedicated apiCredits pool, isolated from chat-product credits.

    Per-key rate-limit tiers with auto promotion

    Rate-limit tiers (free, pay_as_you_go, high_volume, enterprise) are wired in. Promotion runs every 5 minutes against confirmed lifetime top-up. Limits are surfaced live on every response via X-RateLimit-* headers. See the Rate limits page.

    Dashboard at /developers/*

    Sign in and visit /developers for a balance and usage overview, mint and revoke keys at /developers/keys, chart usage by model and by day at /developers/usage, and top up at /developers/billing.

  • 2026-05-09v0.1.0Note

    No first-party SDK in launch

    We did not ship a vendor SDK. The HTTP surface is small enough that any HTTP client works. See Using HTTP clients for copy-paste-ready Python and TypeScript wrappers.
