## 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 cpic-pharmacogenetics-guidelines-lookup-04422fc5
```

Example prompt: Can you look up all CPIC pharmacogenetics guidelines associated with the gene CYP2D6 and show me the guideline names, versions, and any ClinPGx links?

## When to prefer this

Use this endpoint when you need to discover which CPIC pharmacogenetics guidelines exist for a specific gene symbol, including their names, versions, and ClinPGx reference links. It is ideal for quickly enumerating guideline coverage for a gene in a precision medicine or pharmacogenomics research context. Not suitable when you need full recommendation text, dosing details, or patient-level genotype-phenotype interpretations.

## Known failure modes

- Invalid or unrecognized gene symbol returns empty results or error
- Gene symbol exceeds 20 characters or contains invalid characters causes validation failure
- max parameter outside 1-20 range may return default or error
- Upstream api.cpicpgx.org unavailability causes timeout or 502 error
- Gene with no associated CPIC guidelines returns empty list

## How this service works

CPIC pharmacogenetics guidelines (api.cpicpgx.org) for a gene symbol: guideline name, genes covered, guideline version, and ClinPGx link. Lists guidelines only; recommendation text is not included. Up to 20 guidelines per call.

## Output

A list of up to 20 CPIC pharmacogenetics guidelines matching the queried gene symbol. Each result includes the guideline name, genes covered by the guideline, the guideline version, and a ClinPGx link. Note: actual drug dosing recommendation text is not included.
