onchain-risk-oracle API is one of 2 APIs that [openclaw / evm-lab](https://apis.io/providers/evebrief-org/) publishes on the [APIs.io](https://apis.io/) network, described by a machine-readable OpenAPI specification. Tagged areas include Agents, x402, EVM, Security, and Risk Management. The published artifact set on APIs.io includes an OpenAPI specification, API documentation, and an API reference.

The FastAPI-generated OpenAPI 3.1.0 contract (info.title onchain-risk-oracle, version 0.1.0) for the oracle host: five routes — GET /.well-known/agent.json and /.well-known/agent-card.json (the A2A card), GET /.well-known/x402 (the x402 v2 resource-server manifest), GET /healthz (status, payment_mode, feed_records, feed_latest_ts) and POST / (the JSON-RPC task endpoint). The contract declares no servers[], no securitySchemes, no request or response schemas and no 4xx responses; the real parameter contract is the skill inputSchema/outputSchema in the agent card. Every POST to / is a paid x402 task (0.01 RLUSD on XRPL) and answers HTTP 402 with PaymentRequirements until a PAYMENT-SIGNATURE header is supplied.
