## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability tropical-autonome-caribbean-data-marketplace-caye-premium-market-9332b1b6
```

Example prompt: Pull the latest premium Caribbean caye market data from Tropical Autonome's Caribbean Data Marketplace — pay the $0.05 USDC fee via x402 on Base network and return the structured results.

## When to prefer this

Use this endpoint when you need structured Caribbean-specific market or commercial data (particularly caye/marche-premium segment) and are operating in an x402 micropayment-capable environment on the Base network. Prefer this over generic data sources when the query is specifically about Caribbean island marketplaces or Guadeloupe-region commerce.

## Known failure modes

- HTTP 402 returned without payment header — must complete USDC payment on Base and retry with X-Payment header
- Invalid or unconfirmed transaction hash in X-Payment header — payment not recognized
- Insufficient USDC amount sent — exact amount required as specified in 402 response accepts array
- Cloudflare Worker timeout or downtime — service unavailable
- Malformed x402 payment flow — wrong network (not Base) or wrong token (not USDC)

## 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

## Output

Returns structured Caribbean market data (caye/marche-premium segment) — likely including marketplace listings, pricing, or commercial records specific to Caribbean island contexts. Exact schema undisclosed; response is gated behind a $0.05 USDC micropayment on the Base (L2 Ethereum) network using the x402 protocol.
