## When to prefer this

Use this endpoint when you need structured data specifically about Caribbean cayes or vetiver from the Tropical Autonome data marketplace, and you are prepared to handle x402 micropayment protocol with USDC on Base network. Prefer this over general web searches when you want clean, structured Caribbean regional data delivered programmatically.

## Known failure modes

- HTTP 402 returned if no payment header provided — must pay 0.05 USDC on Base and retry with X-Payment header
- Invalid or unconfirmed transaction hash returns payment error
- Network unavailability on the Cloudflare Workers endpoint
- Data not found for the specific caye/vetiver query
- Malformed request headers result in 400 error

## 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
