## 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-biodiversity-credits-cd62c9d3
```

Example prompt: Can you pull the latest biodiversity credit data for the Caribbean from the Tropical Autonome marketplace? I need the structured records from their biodiversite credits endpoint.

## When to prefer this

Use this endpoint when you need structured biodiversity credit or ecological offset data specifically for the Caribbean region, particularly for Guadeloupe and surrounding territories. Prefer this over generic environmental data sources when you need Caribbean-specific, AI-agent-ready structured data with micropayment access via the x402 protocol on Base network.

## Known failure modes

- HTTP 402 returned if payment header is missing or payment not confirmed — must send USDC on Base network and retry with X-Payment header containing transaction hash
- Invalid or unconfirmed transaction hash causes payment rejection
- Network latency or Cloudflare Workers cold start may cause occasional timeouts
- Endpoint may return empty data if no credits are currently listed
- Malformed payment header format causes authentication failure

## 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 biodiversity credit data, including ecological credit records and related metadata relevant to biodiversity offsets or natural capital tracking in the Caribbean region.
