One endpoint. Every tool.

Add the router and a wallet to Claude Code. From then on, your agent can discover tools, pay for them, and get answers.

Tools

Verdicts, not tables

Every tool turns onchain state into a decision, and tells the agent when the data isn't trustworthy.

Lending rates

by OnchainRouter
$0.01

Best place to lend or borrow an asset, weighed against liquidity depth.

Best supply rate: 4.86% on compound-v3, backed by $375.4M of liquidity. iron-bank reports 75.10%, far outside what every live market on this chain pays. Read as stale data from an abandoned protocol, not an offer. Next best is aave-v3 at 3.62%, 1.23 points behind.

Governance power

by OnchainRouter
$0.01

How concentrated a protocol's voting power is, and how much of it never votes.

4 delegates acting together reach quorum: concentrated, but not captured by two or three. The ten largest delegates hold 53.8% of delegated votes. One of them has never cast a vote, holding 5.5% on its own.

How it works

Three steps, no signup anywhere

01

Connect once

Add the router as an MCP server. Your agent sees every tool in the catalogue, with its price, straight away.

02

Call a tool

The first call returns 402 with the price and payment rails. Nothing is charged yet.

03

The agent pays, for an answer

The agent signs with its own wallet. The tool runs and returns the answer. If it has nothing to say, the payment is never settled.

For tool authors

Get discovered. Get paid. Keep 100%.

Wrap your API in x402 with one call, or list an endpoint that already speaks it. Agents find it, call it, and pay you directly. The router takes nothing.

Discovered. In the catalogue and over MCP, in front of every agent that connects.
Paid directly. Every call settles from the agent's wallet to your address. No invoice, no payout run, no minimum.
Your terms. Your price, your wallet, your server. Onepaid() call if you are not on x402 yet.
0%commission

Payment rails

One tool. Multiple payment rails.

The agent chooses how to pay. The tool doesn't care.

FAQ

Questions, answered

No. Identity is the wallet that pays. Connect to the MCP URL or call the HTTP endpoint and you are in.
0.1 HBAR on Hedera or 0.01 USDC on Arc, per call. Listing the tools is free, and so is a call that returns no answer.
Nobody in between. The 402 names the tool author's address and the payment settles from your agent's wallet straight to it. The router has no wallet, no balance and takes no commission.
It says so and you are not charged. On HTTP that is a 404; over MCP an error result. The signed payment is never settled.
From its own wallet. In code, npm install onchainrouter and pay(url, input, wallet). In Claude Code, add the router and npx onchainrouter wallet as two MCP servers; the wallet signs when a tool asks. See Connect.
Not yet. Both rails run on testnet: Hedera testnet through Blocky402 and Arc testnet through Circle Gateway. Real settlements, test money.
The Graph, through Messari's standardized subgraphs, so one tool asks every lending protocol on a chain the same question. Coverage is measured by a probe, not claimed.
Yes. Wrap your function with paid() from the onchainrouter package, or bring an endpoint that already speaks x402 on Hedera or Arc. Agents can list tools too, over submit_tool on MCP. See Submit.
