# x402.press

> Pay-per-call AI services using wallet-based micropayments. Each request is gated by a HTTP 402 Payment Required handshake — the client sends a micro-payment in USDC/EURC, and the server responds with the result. No subscriptions, no API keys, no accounts. Just pay for what you use.

**Machine-readable catalog of all services (endpoints, per-chain prices, doc links):** `https://x402.press/catalog.json` (also at `https://x402.press/.well-known/x402.json`). Generated from every service's Service Contract.

## Wallet

All x402 services require a connected wallet with USDC or EURC balance. Supported chains: Base (USDC/EURC), Arbitrum (USDC), Polygon (USDC), Avalanche (USDC). Payments settle via the x402 facilitator protocol — instant authorization, batched onchain settlement.

The recommended end-user interface is **Agent Chat** at `chat.x402.press`, which handles wallet connection, service discovery, and payment routing automatically.

## What It Is

Agent Chat is a product, not an API. It's a conversational interface where an AI agent handles all the complexity — wallet management, payment routing, service discovery, and multi-step task execution. Users just talk to it.

The agent has access to 11 specialized x402.press services and can combine them in a single conversation. Ask it to check the weather, track a flight, research a news topic, generate music, or run a scientific computation — it routes the request to the right service, handles the payment, and brings back the result.

---

## How It Works

1. **Visit** `https://chat.x402.press`
2. **Sign up** with email (Privy handles authentication)
3. **Top up** your balance with USDC (credit card or crypto transfer)
4. **Start chatting** — ask questions, request tasks, explore services
5. **Pay per interaction** — agent reasoning and service calls are deducted from your balance
6. **Monitor balance** — top up again when low

---

## What You Pay For

Every interaction costs money from your balance:

- **Agent reasoning** — the AI thinking through your problem
- **Service calls** — each x402 service call (News, STEM, Weather, etc.)
- **Web research** — if the agent searches the web for information

There is no free tier. Every action has a cost, and the agent is transparent about what it's doing and what it costs.

---

## What You Don't Need to Do

- ❌ Configure a crypto wallet
- ❌ Set up API keys
- ❌ Understand the x402 protocol
- ❌ Handle payment signing
- ❌ Discover service endpoints
- ❌ Write code

The agent handles all of this automatically.

## Future Direction

Agent Chat is evolving into the central interface for function-specific x402 services. Financial Analyst and Trade Analyst are live as x402 services (see the Services section above); planned additions include:

- **Legal Advisor** — legal research and document analysis
- **Medical Research Assistant** — medical literature and research synthesis
- **Business Intelligence** — market research and competitive analysis

The vision: Agent Chat becomes the primary way users access specialized AI capabilities — a single interface for any function-specific service, without technical setup.
