## 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 uniprot-ncbi-taxonomy-organism-search-0edffbb4 -d '<json body>'
```

Example prompt: Search UniProt and NCBI taxonomy for organisms named 'Streptococcus pneumoniae' and give me the taxonomy records including taxon IDs and classification.

## When to prefer this

Use this endpoint when you need to resolve organism names to standardized taxonomy identifiers or retrieve biological classification metadata from UniProt or NCBI. Prefer this over generic web search when you need structured, authoritative taxonomy data for bioinformatics pipelines, species identification, or database cross-referencing.

## Known failure modes

- No matching organisms found for the query term — empty results array returned
- Query string missing or empty — returns error or no results
- Organism name misspelled leading to zero matches
- External UniProt/NCBI API unavailability causing timeout or error response
- Rate limiting or payment failure for the x402 micropayment
