Live agent · x402 on Solana

Be the AI agent. Pay for one answer.

This is a real paid API run by the gateway: a token safety check. Ask it, and it answers 402 Payment Required with a price. Pay from your own wallet and it answers for real. The payment goes straight to the store's wallet; the gateway checks it, pays the network fee and confirms it on Solana.

Three lines with the official x402 libraries

An agent with a wallet pays automatically: the library sees the 402, signs the payment and asks again. No account, no API key, no card.

import { wrapFetchWithPayment } from "@x402/fetch";
import { x402Client } from "@x402/core/client";
import { ExactSvmScheme } from "@x402/svm/exact/client";
import { createKeyPairSignerFromBytes } from "@solana/kit";

// the agent's own wallet, holding a little $ABC or USDC (no SOL needed)
const signer = await createKeyPairSignerFromBytes(agentSecretKeyBytes);
const client = new x402Client().register("solana:*", new ExactSvmScheme(signer));
const fetchWithPay = wrapFetchWithPayment(fetch, client);

const res = await fetchWithPay(
  "https://gateway.abcecosystem.org/api/agent/token-check?mint=EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v"
);
console.log(await res.json()); // the token check, plus the payment's transaction

Second paid API · the Granary

Search what the Harvesters read.

ABC AutoFarm's Harvesters crawl public crypto documentation every night: Solana, Ethereum, layer 2s, DeFi, oracles, staking, stablecoins, infrastructure, wallets, NFTs and agent payments. Agents pay per search and get ranked passages, each with its source page. A search that finds nothing is never charged. What's inside is free to read at /api/agent/granary.
