Built on the x402 Protocol

The Payment Layer for Autonomous AI Agents

Enable your AI agents to pay for APIs in real time with USDC micropayments. Control spending, enforce policies, and own your transaction graph.

x402 Payment Flow
// Agent requests a paid API endpoint
GET https://api.weather.com/forecast
// Server responds with payment required
402 Payment Required
x402-price: 0.001 USDC x402-chain: base
// Agent auto-signs payment & retries

How It Works

Three steps to autonomous commerce

From funding to settlement in under 2 seconds

Step 1

Fund

Load Agent Wallets

Organizations deposit USDC or use the fiat on-ramp. Set daily budgets, vendor allowlists, and spending policies for each agent.

Step 2

Transact

Agents Pay for APIs

When an API returns HTTP 402, the agent automatically signs a USDC micropayment. Sub-second settlement on Base and Solana.

Step 3

Earn

Sellers Get Paid

API providers receive instant USDC payments. No invoicing, no chargebacks, no 30-day net terms. Just revenue.

Features

Everything you need for agent commerce

A complete payment infrastructure built for autonomous AI agents

Real-time Analytics

Track every transaction as it happens. Live dashboards with spend breakdowns, success rates, and latency metrics.

Multi-chain Support

Lightning-fast settlements on Base (2s finality) and Solana (400ms). Pay with USDC stablecoins across chains.

Smart Policies

Enforce budget caps, vendor allowlists, and per-request limits. Every payment is policy-checked before signing.

Developer First

Add 3 lines to monetize any API. TypeScript SDKs for Express, Hono, LangChain, and MCP tool servers.

Instant Settlement

Non-reversible USDC micropayments with no chargebacks. Sellers get paid the moment the API responds.

Open Protocol

Built on the x402 HTTP standard. Fully interoperable, no vendor lock-in. Any agent, any API, any chain.

Integration

Ship in minutes,
not weeks

Sellers add a middleware to monetize APIs. Buyers create an agent wallet that auto-handles x402 payments. That's it.

TypeScript SDKs for Express, Hono, and LangChain

Budget policies, rate limits, and vendor ACLs built-in

Works with any HTTP client — fetch, axios, or custom agents

// Monetize any API — add 3 lines
import { paywall } from "@apitoll/middleware";
app.use(paywall({
"GET /api/forecast": { price: "0.005", network: "base" },
"POST /api/analyze": { price: "0.02", network: "base" },
}));
