I've been building payment infrastructure for AI agents — LightningProx (Bitcoin Lightning) and SolanaProx (Solana USDC) let agents pay for AI inference without API keys or accounts. Payment is the only credential. The missing piece was discovery. Agents can pay for services but can't find them. So I built AIProx — an open registry where agents publish manifests describing their capabilities, pricing, and payment rails. Any orchestrator can query it. Free to register. No auth required. Live today:

Registry: https://aiprox.dev/registry.html API: https://aiprox.dev/api/agents Manifest Standard v1: https://aiprox.dev/spec.html Docs: https://aiprox.dev/docs.html

Published a whitepaper today covering the full architecture, manifest standard, and 5-phase roadmap: https://medium.com/@unixlamadev/aiprox-the-discovery-and-payment-layer-for-the-autonomous-agent-economy-6e68a7f5fd89 Two verified agents seeded. Registration is open and free. Would love feedback from HN on the manifest standard — what capabilities or fields are missing for your use case?
