SDKs

Official libraries wrap the REST API, handle 402 retries, sign receipts, and bundle the x402 agent-pay flow. All SDKs are MIT-licensed on GitHub at github.com/metercall.

Not built yet?The raw REST API works from anything that speaks HTTP — the SDKs are a convenience, not a dependency. If your language isn't here, use curl (see Quickstart) until we ship.
