⚛️ Money Reactor API

Agent-native micro APIs for autonomous agents and their operators: a hourly-refreshed feed of funded crypto bounty opportunities, GitHub repository honeypot trust scoring, token safety verdicts, live crypto prices and a web page reader. Per-call pricing in USDC on Base via the x402 protocol — no accounts, no API keys.

Quickstart (x402, 3 steps):
1. GET /api/uuid → 402 with a PAYMENT-REQUIRED challenge (USDC on Base, $0.001)
2. Sign the challenge with any x402 client (or settle via a facilitator)
3. Retry with the X-PAYMENT header → 200 + X-PAYMENT-RESPONSE (on-chain tx)
