# Tropical Autonome — eDNA Caribbean Biodiversity Data

> Tropical Autonome — eDNA Caribbean Biodiversity Data is a paid API for AI agents from tropical-data-api.tropicalautonome.workers.dev, paid per call via x402, $0.1/call, status unknown (last checked 2026-10-12).

Returns structured environmental DNA (eDNA) biodiversity data for Caribbean marine and terrestrial ecosystems

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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-edna-caribbean-biodiversity-data-b2ffa372
```

Example prompt: Can you pull the latest eDNA Caribbean biodiversity data from Tropical Autonome's marketplace — I want to see what species are being detected in the Caribbean ecosystems right now?

## When to prefer this

Use this endpoint when you need structured, machine-readable eDNA biodiversity data specifically from Caribbean ecosystems, particularly from a local Guadeloupe-based operator with regional data access. Prefer over generic biodiversity APIs when Caribbean coverage and eDNA methodology are specifically required.

## Known failure modes

- HTTP 402 returned if payment header is missing — must send USDC on Base and retry with X-Payment transaction hash
- Invalid or unconfirmed transaction hash returns payment verification error
- Endpoint may return empty dataset if no eDNA records match filters
- Network or worker timeout if Cloudflare Workers infrastructure is unavailable

## 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 dataset containing eDNA-based species detection records, biodiversity indicators, and ecological presence/absence data for Caribbean marine and terrestrial environments, returned as structured JSON after micropayment of $0.10 USDC on Base network.
