GetBindu/Bindu

getbindu/bindu is a Python library that provides an identity, communication, and payments layer for AI agents behind a single function call. It enables developers to wrap custom agent handlers with A2A JSON-RPC communication, W3C DID signatures, mTLS, OAuth2, and USDC payment enforcement.

Project overview

Project type: AI Agent · Infrastructure
Use cases: Automation
Deployment: Refer to project documentation
License: License pending

Best for

Developers and AI engineers building agent systems who require secure, mutually authenticated network communication and decentralized identity verification.
Enterprise teams needing to deploy agents that validate caller authorization and negotiate service-level agreements before executing tasks.

Key capabilities

Exposes agents via A2A JSON-RPC supporting message/send, tasks/get, and message/stream.
Encrypts sockets and mutually authenticates them using X.509 certs from step-ca.
Signs agent responses with Ed25519 keys, allowing verification via W3C DID.
Validates caller authorization using scoped bearer tokens via Ory Hydra introspection.
Allows agents to demand USDC payments on EVM chains before executing work.
Enables agents to declare capabilities visible on their agent card.
Allows two agents to agree on price, latency, and SLA up front.
Exposes local agents to the internet via an FRP tunnel without port forwarding.

Limitations and risks

Requires Python 3.12 or higher.
Requires an API key for at least one LLM provider to run examples.
Has documented known issues that should be read before pushing to production.

Getting started

Install the uv package manager, run uv add bindu, configure an LLM API key such as OPENAI_API_KEY, and write a script to wrap your agent handler with bindufy().

README: You'll need Python 3.12+ and [uv](https://github.com/astral-sh/uv).
README: Bindu is all of that plumbing, behind one function call. You wrap your handler with `bindufy()`, and a few seconds later your agent is online with its own cryptographic identity
README: We're using Bindu in production to build the **Trade Compliance OS**
Release: 2026.22.4: x402 settle-first + scenario hardening
