Open x402 v2 SDK. EIP-3009 on Base. Free forever.
One package, two languages, byte-identical wire format.
npm install hive-rosetta
pip install hive-rosettax402 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.
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');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 URLc = 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-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.
