# RelAI — x402 API Marketplace

## What is RelAI?

RelAI is an x402 protocol marketplace for pay-per-call API micropayments.
API providers register their endpoints and set per-call USD prices.
Consumers (humans or AI agents) pay automatically using crypto wallets — no subscriptions, no API keys to manage.

The x402 protocol works by returning HTTP 402 Payment Required with a payment challenge.
The client signs a payment, retries the request with proof, and the server proxies the call after verifying payment on-chain.

## Networks supported

- Solana (USDC)
- Base (USDC)
- SKALE Base (USDC, multi-token, gas-free)
- Avalanche (USDC, gas-free via 0xGasless)
- Ethereum (USDC)
- Polygon (USDC)

## For AI agents — how to use RelAI

### Step 1: Get a service key (no human login required)

Autonomous agents can bootstrap a service key using a wallet signature challenge-response flow.
Supports both Solana (ed25519) and EVM (secp256k1) wallets.

POST https://api.relai.fi/mcp/management/bootstrap/agent
Body: { "publicKey": "<your-agent-public-key>" }
Response: { "message": "<challenge-to-sign>" }

POST https://api.relai.fi/mcp/management/bootstrap/agent
Body: { "publicKey": "...", "signature": "...", "message": "...", "label": "my-agent" }
Response: { "key": "sk_live_..." }

Store the key securely. Use it as X-Service-Key header for all management calls.

### Step 2: Connect via MCP

Add to your MCP client config:

{
  "mcpServers": {
    "relai-management": {
      "url": "https://api.relai.fi/mcp/management",
      "headers": { "X-Service-Key": "sk_live_..." }
    }
  }
}

### Step 3: Discover and call APIs

Browse the marketplace:
GET https://api.relai.fi/marketplace

Get API details (endpoints, pricing, network):
GET https://api.relai.fi/marketplace/:apiId

Call any listed API using the x402 protocol via the RelAI SDK or manually.

## For API providers — register your API programmatically

POST https://api.relai.fi/v1/apis
Header: X-Service-Key: sk_live_...
Body: {
  "name": "My Inference API",
  "baseUrl": "https://inference.example.com",
  "network": "base",
  "merchantWallet": "0xYourWallet",
  "endpoints": [
    { "path": "/v1/predict", "method": "post", "usdPrice": 0.05 }
  ]
}

The API is immediately functional for x402 calls. It will appear in the public marketplace after review.
