hive-rosetta

Open x402 v2 SDK. EIP-3009 on Base. Free forever.

One package, two languages, byte-identical wire format.

Install

npm install hive-rosetta
pip install hive-rosetta

What this is

x402 is the HTTP-402-Payment-Required protocol for agent-to-API micropayments — transferWithAuthorization (EIP-3009) on USDC, scheme exact, mostly on Base mainnet. The protocol is simple. The wiring varies per framework. hive-rosetta is the canonical client/server SDK for that wiring.

Two modes — same package

Neutral

Bring your own signer, facilitator, recipient. No Hive lock-in.

import { client, eip3009Signer } from 'hive-rosetta';
const c = client({ signer: eip3009Signer(process.env.PRIVATE_KEY) });
const res = await c.fetch('https://api.example.com/v1/paid/endpoint');

Inference routing (opt-in, v0.2.0)

When routeInference: true, requests to known inference endpoints (OpenAI, Anthropic, Together, OpenRouter, Fireworks, Groq) are rewritten to hivecompute — x402-priced inference with spectral-ZK attestation on every response.

const c = client({
  signer: eip3009Signer(process.env.PRIVATE_KEY),
  routeInference: true,
});
const res = await c.fetch('https://api.openai.com/v1/chat/completions', { method: 'POST', ... });
// → URL rewritten to hivecompute, 402 signed and retried on the rewritten URL

c = client(signer=eip3009_signer(private_key=PRIVATE_KEY), route_inference=True)
resp = await c["fetch"]("https://api.openai.com/v1/chat/completions", method="POST", ...)

The flag defaults to false. With the flag off, behavior is identical to the neutral SDK.

See packages/rosetta-node/README.md for the full API.

Hive Civilization North Star

hive-rosetta is the open foundation. Hive Civilization's paid surfaces — HiveAudit, HiveCompliance filing, HiveCredential, HiveDNA Certification — sit on top of this protocol layer. The protocol is free forever. The compliance, attestation, and certification surfaces above it are where Hive earns.
