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 saylor-innovations-data-desk-catalogue-of-life-species-search-7f7796f2
```

Example prompt: Can you look up Panthera leo in the Catalogue of Life and give me its full kingdom-to-genus classification, authorship, and current accepted status?

## When to prefer this

Choose this endpoint when you need authoritative taxonomic classification data from the Catalogue of Life — particularly when verifying accepted species names, resolving name authorship, or retrieving the full kingdom-to-genus hierarchy for a taxon. Prefer this over general web search when you need structured, machine-readable taxonomic data with canonical identifiers and status flags.

## Known failure modes

- No taxa found for the query string (empty taxa array, total=0)
- Query too vague returns unrelated or excessive results — use more specific name fragment
- limit parameter outside 1-15 range may be ignored or cause an error
- Misspelled scientific names may return zero results or incorrect matches
- Rare taxa not yet indexed in the Catalogue of Life will not appear

## How this service works

Search the Catalogue of Life for accepted taxa - scientific name, authorship, rank, status, kingdom to genus classification and a link for each match

## Output

A JSON object containing the interpreted query string, total number of matches, count of returned items, the data source attribution, and an array of matching taxa — each with a unique ID, scientific name, authorship, taxonomic rank, accepted status, kingdom through genus classification fields, full classification path, and a canonical Catalogue of Life URL.
