Agent API & Integrations
Greenlight exposes a machine-readable API for autonomous AI agents to perform pre-action security checks before committing to irreversible crypto transactions. Returns signed findings payloads — not verdicts.

Security Checks Reference
Full breakdown of every API check, finding code, severity, and trigger condition.

SDK & Platform API
Greenlight is expanding beyond a scanner into a pluggable security platform. The SDK wraps the full API surface so any agent runtime, game server, or app can integrate in a few lines of code — no HTTP boilerplate.
New Endpoints
POST /v1/policy/validate
In Development
Submit a Greenlight DSL policy — returns a signed clearance confirming the agent's standing policy is valid and compliant
POST /v1/attestations
In Development
Issue an on-chain EAS attestation after a successful scan — contracts can require a valid attestation before allowing interaction
GET /v1/attestations/:id
In Development
Verify a prior attestation by ID — any party can confirm a scan cleared without re-running it
JavaScript / Python SDK
Three methods cover the full security lifecycle — scan, policy, and on-chain proof. Works in any agent skill, MPC workflow, or server-side integration.
greenlight.check(address, intent) // scan + signed findings
greenlight.policy(dsl) // validate DSL, get clearance
greenlight.verify(attestationId) // confirm on-chain attestation
Support Development
If you find value with Greenlight, help keep it free and secure for everyone.
