Framework integrations

Copy-paste tool definitions wired to Ontario's four x402-paid endpoints. Pair with an x402 client (e.g. the x402 Python example) so 402 responses are signed and retried automatically.

OpenAI tool calling

Drop-in OpenAI function/tool definitions for the four Ontario Protocol paid endpoints. Pair with an x402 client (e.g. the x402 Python SDK) to actually pay each call.

Machine-readable

Each framework also has a JSON descriptor at /integrations/<framework>.json carrying the per- framework tool shape and the four endpoint schemas.

Preflight SDKs

Agents can call Ontario before spend with the Python helper or TypeScript helper.
