Show HN: Bindu – an auth, payment, and communication layer for AI agents (github.com)

Bindu is an open-source “operating layer” that turns single AI agents into discoverable, secure, interoperable services on an emerging Internet of Agents. Built on open protocols A2A, AP2 and X402, Bindu adds authentication, payments, observability, distributed execution and low-latency networking so agents can trust, trade and communicate with each other out of the box. Developers write their agent in any framework (examples: Agno, CrewAI, LangChain, LlamaIndex, FastAgent), add a small JSON config and a handler, then call bindufy to expose the agent as a live endpoint (demo at http://localhost:3773). The repo is Apache‑2.0, has >70% test coverage, and includes tooling for quick local setup and CI. For the AI/ML community this matters because it lowers the plumbing barrier for multi-agent systems: instead of building bespoke bridges for auth, payments, discovery and cross-agent messaging, teams can adopt a protocol-first stack that supports decentralized execution and economic interactions between agents. That enables richer agent collaboration patterns (gossip, negotiation, marketplaces) and faster experimentation with composable agent architectures. Roadmap items—gRPC transport, Sentry, Redis scheduler, Postgres memory, OAuth/Cognito auth, full AP2/X402 support—signal expansion toward production-grade deployments and enterprise integrations.
