# Species Name Resolution & Taxonomy Lookup

> Species Name Resolution & Taxonomy Lookup is a paid API for AI agents from biodiversity.x402tookit.com, paid per call via x402, $0.03/call, status unknown (last checked 2026-10-30).

Resolves a species name (including typos and synonyms) to its accepted scientific name and full taxonomy, with match confidence score.

## 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 species-name-resolution-taxonomy-lookup-d4038274
```

Example prompt: Can you resolve 'Pumaa concolorr' to its correct accepted scientific name and give me the full taxonomy — kingdom, phylum, class, order, family, genus, and species — along with how confident the match is?

## When to prefer this

Use this endpoint when you need to canonicalize or validate a species name before downstream processing — especially when dealing with user-entered names, historical literature, or field data that may contain typos or outdated synonyms. Prefer this over general search when you have a specific name to resolve and need a confidence score and synonym flag. It is the right first step before looking up IUCN status, occurrence records, or building a species profile.

## Known failure modes

- Name not found in GBIF backbone — returns low confidence or null accepted name
- Highly ambiguous name matches multiple taxa — returns best match but low confidence
- Network timeout or upstream GBIF API unavailability — degraded flag set to true
- Completely unrecognizable input string — returns null matchedName and no taxonomy
- Missing required 'name' query parameter — request rejected with validation error

## How this service works

Resolve a species name (typos, old synonyms) to its accepted scientific name and full taxonomy, with match confidence.

## Output

Returns the accepted scientific name, accepted canonical name, matched name, full taxonomy (kingdom, phylum, class, order, family, genus, species), taxon key, match type, match confidence score (0-1), whether the input was a synonym, GBIF source URL, and a human-readable summary and verdict. Also includes degraded-mode and disclaimer flags if data quality is limited.
