SRA-RiskGate is a Python SDK that provides deterministic pre-filtering rules for stablecoin and AI-agent payments, including OFAC SDN address checks, depeg monitoring, and self-asserted claim detection, with integrations for x402 and Coinbase AgentKit. It also includes a 4B-parameter model for full policy review, backed by a reproducible evaluation benchmark. The project addresses a niche but growing need for safety guardrails in autonomous payment flows.

Target audience: backend devs, AI agent developers, crypto/DeFi engineers
