## 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-subcellular-location-search-0306df7f -d '<json body>'
```

Example prompt: Can you search the UniProt subcellular location vocabulary for terms matching 'nucleus' so I can annotate my protein dataset with the correct controlled vocabulary identifiers?

## When to prefer this

Use this endpoint when you need to resolve or look up controlled vocabulary terms for protein subcellular localization as defined by UniProt — ideal for bioinformatics pipelines, protein annotation workflows, or when building queries against UniProt databases that require standardized location identifiers.

## Known failure modes

- Empty result set if keyword matches no known UniProt subcellular location terms
- HTTP 402 if payment header is missing or malformed
- Unexpected JSON structure if the query parameter 'q' is omitted
- No results for very specific or misspelled location terms

## How this service works

Search UniProt subcellular location terms by keyword {q}. Query: ?q= Returns JSON.

## Output

A JSON array or object containing UniProt subcellular location entries matching the keyword query — including location names, identifiers, and related metadata from the UniProt controlled vocabulary.
