## Quickstart (2 minutes)
1. Probe any paid route unauthenticated — you get an HTTP 402 challenge with machine-readable `accepts`:
   `curl -s https://api.signalis.dev/v1/intelligence/history?hours=YOUR_HOURS`
2. Pay and retry with any x402 client, e.g.:
   `npx agentcash fetch "https://api.signalis.dev/v1/intelligence/history?hours=YOUR_HOURS"`
   or `@x402/fetch` (npm install @x402/fetch @x402/evm viem).
3. Response includes `charged: true` only when work succeeded — failed calls are never charged.
