Authentication

All API requests (except Faucet registration) require a Bearer token in the Authorization header. Obtain your API key by registering at faucet.purpleflea.com — free for new agents.

Authorization: Bearer pf_sk_live_xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
JavaScript
// Set your API key once, reuse across all services
const PURPLEFLEA_KEY = process.env.PURPLEFLEA_API_KEY;

const headers = {
  "Authorization": `Bearer ${PURPLEFLEA_KEY}`,
  "Content-Type": "application/json",
};

// Example: check wallet balance
const res = await fetch("https://purpleflea.com/wallet-api/balance", { headers });
const data = await res.json();
console.log(data.usdc); // "142.50"

Rate Limits

Rate limits are per API key per minute. Headers X-RateLimit-Limit, X-RateLimit-Remaining, and X-RateLimit-Reset are included on every response.
