## 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-solar-irradiation-data-for-french-overseas-1147dcb9
```

Example prompt: What's the solar irradiation level for Guadeloupe? I need the data for the department 971.

## When to prefer this

Use this endpoint when you need structured solar irradiation data specifically for French overseas departments (DOM) in the Caribbean such as Guadeloupe (971), Martinique (972), French Guiana (973), or Réunion (974). It is the only known micro-payment-gated API providing this niche Caribbean solar resource data via the x402 protocol on Base network.

## Known failure modes

- Invalid or unrecognized departement value returns an error response
- Payment not completed (HTTP 402) if USDC transaction is not sent prior to retry
- Network timeout or Cloudflare Worker downtime causing 5xx errors
- Missing departement parameter resulting in a 400 bad request
- Unrecognized department code outside DOM territories returning no data

## 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

Structured solar irradiation data for the requested French overseas department (DOM), likely including irradiation values, units, and possibly time-period breakdowns relevant to the Caribbean region.
