Typed end to end
Request and response types are generated with every release, so a breaking change fails at compile time.
Retries that behave
Jittered exponential backoff on 429 and 5xx, capped by the rate-limit reset header. Never on a 4xx you can fix.
Streamed by default
Consume run events over SSE with a typed async iterator. Backpressure and reconnects are handled.
Zero runtime deps
4.7 kB gzipped. ESM and CJS builds, Node 20+, Bun, Deno and edge runtimes.
