ToolOracle x402 v2 Compliance, Evidence & Agent-Safety API is one of 5 APIs that [FeedOracle Technologies](https://apis.io/providers/tooloracle-io/) publishes on the [APIs.io](https://apis.io/) network, described by a machine-readable OpenAPI specification. Tagged areas include x402, Compliance, Sanctions Screening, and Agent Safety. The published artifact set on APIs.io includes an OpenAPI specification, API documentation, a getting-started guide, and pricing.

Account-less pay-per-call REST API (OpenAPI 3.1.0 with schemas and examples on every operation): agent action preflight, MiCA stablecoin compliance, AML/sanctions screening, CVE lookup, UVO claim and citation verification, and a US macro snapshot. Every route follows x402 v2 — an unpaid POST returns HTTP 402 with a PAYMENT-REQUIRED challenge (USDC on Base, EIP-3009 exact scheme, CDP facilitator); retry with PAYMENT-SIGNATURE; paid responses carry an Ed25519-signed execution receipt.
