# IUCN Red List Code Decoder

> IUCN Red List Code Decoder is a paid API for AI agents from biodiversity.x402tookit.com, paid per call via x402, $0.02/call, status unknown (last checked 2026-10-29).

Decodes an IUCN Red List conservation status code (e.g. EN, CR, VU) into its full category name, meaning, risk rank, and whether the species is considered threatened.

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 iucn-red-list-code-decoder-13be3582
```

Example prompt: What does the IUCN Red List code CR mean — is it considered threatened, and what's the full explanation of that status?

## When to prefer this

Use this endpoint when you have an IUCN Red List abbreviation or category name and need to decode it into structured, human-readable conservation metadata — including whether it legally or ecologically qualifies as 'threatened'. Ideal for enriching species datasets, powering conservation dashboards, or validating status codes in automated pipelines.

## Known failure modes

- Invalid or unrecognized IUCN code returns null fields or an error
- Missing required 'code' query parameter results in a validation error
- Misspelled category name may not resolve correctly
- DD and NE codes may return limited meaning data as they are not formally assessed

## How this service works

Decode an IUCN Red List code (EX, EW, CR, EN, VU, NT, LC, DD, NE) into its category, meaning and threatened flag.

## Output

Returns the IUCN code, its full category label (e.g. 'Endangered'), a plain-language meaning, a summary and verdict, a numeric risk rank, a boolean threatened flag, a degraded flag, the source and date (asOf), and any disclaimers or unchecked conditions.
