Thread Notes
Probe runs 44 automated compliance and security checks on any API endpoint in under 5 seconds.
Built for AI agent developers and API providers who need to verify trust, security, and regulatory readiness before integration โ or before an agent makes its first payment.
Compliance & Regulatory - EU AI Act Article 14 โ human oversight signals - FATF Travel Rule readiness - Terms of Service and Privacy Policy endpoint detection - MiCA-relevant metadata checks
Agent Infrastructure - x402 payment protocol support - ERC-8004 on-chain agent identity verification - MCP server discovery - agent.json and Google A2A protocol detection
Security & Trust - SSL/TLS configuration and certificate health - DNSSEC, CAA, DMARC/SPF email authentication - Authentication maturity (OAuth2, OIDC, API keys) - Content-Type, CORS, and security headers
API Standards - Versioning and deprecation (Sunset headers) - Rate limiting and error handling - Response format consistency
How it works: - Instant audit โ no signup, no API key - Results in under 5 seconds - Pass/fail for each of the 44 checks - Overall compliance score (0-100) - Public leaderboard ranking 200+ APIs - JSON API for CI/CD pipelines - Free tier available
In an economy where agents choose which APIs to trust and pay, Probe is the credit check that runs before the first transaction.

Probe is the only tool that checks AI agent-specific protocols like x402 payment headers, ERC-8004 on-chain identity, and EU AI Act Article 14 human oversight signals โ alongside traditional security checks like SSL/TLS, DNSSEC, and DMARC. No other compliance scanner covers the AI agent economy stack.
GetProbe.xyz's answer
Most compliance tools focus on GDPR or generic web security. Probe covers 32 checks across both traditional security AND emerging AI agent protocols (x402, MCP, agent.json, Google A2A). It runs in under 5 seconds, requires no signup, and provides a public leaderboard so you can benchmark against 200+ APIs instantly.

AI agent developers, API providers, DevOps engineers, and compliance teams who need to verify that APIs meet security, trust, and regulatory standards before integration. Especially relevant for teams building in the x402/MCP/A2A agent economy.
GetProbe.xyz's answer
We built Probe because AI agents are starting to pay for and consume APIs autonomously โ but there was no way to verify if an API is trustworthy before an agent sends money to it. Probe started as an internal tool at AsterPay to audit x402-compatible APIs, then grew into a standalone compliance platform covering 32 checks across security, identity, and regulation.
