## When to prefer this

Use this endpoint when you need structured, machine-readable fiscal data for French overseas territories (DOM) pertaining specifically to Article 244 quater W of the French General Tax Code. Prefer this over general French tax databases when you need Caribbean/DOM-specific data accessible programmatically via a paid API with x402 micropayment protocol.

## Known failure modes

- Invalid or unsupported departement code returns error or empty result
- HTTP 402 returned if payment header is missing or invalid — must pay 0.1 USDC on Base network and retry with X-Payment header
- Transaction hash not yet confirmed on Base network leads to payment rejection
- Endpoint unavailable or worker error (5xx) if the Cloudflare Worker is down
- No data available for the requested territory code

## How this service works

Single entry point for AI agents accessing structured Caribbean data.

**Payment protocol (x402):**
1. Call any paid endpoint → receive HTTP 402 with `accepts` array (x402Version 1)
2. Send exact USDC amount to the `payTo` address on Base network (L2 Ethereum)
3. Retry with header: `X-Payment: 0x{transaction_hash}`

**Currency:** USDC on Base network
**Operator:** Tropical Autonome — Lamentin, Guadeloupe (971)
**Contact:** tropicalautonome@gmail.com
