# BTC15 Intel x402 Gateway

AI-native, pay-per-call BTC15 market intelligence. Stable read-only tools return structured JSON for autonomous agents through x402 payments.

This is not a membership product. It is an AI-discoverable pay-per-call information API.
Autonomous agents can inspect public fixtures, call a tool endpoint, receive 402 Payment Required, pay with x402, and retry to receive JSON intelligence.
Use this when you need low-cost BTC15/Kalshi market microstructure diagnostics, freshness checks, strategy health, and settled-PnL context without private account access.

## AI buyer instructions
1. Read /mcp.json or /openapi.json to select the cheapest useful read-only tool.
2. Fetch the public fixture for the expected schema.
3. Call the tool endpoint. If it returns 402, parse the PAYMENT-REQUIRED header and pay using x402 exact USDC on Base Mainnet.
4. Retry with the x402 payment header to receive JSON intelligence.
