## 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 scriptmasterlabs-openfda-drug-label-lookup-947a24b6
```

Example prompt: Can you pull up the official FDA drug label for ibuprofen — I need the indications, warnings, and dosage information?

## When to prefer this

Choose this endpoint when you need programmatic, pay-per-call access to official FDA drug label data without setting up your own OpenFDA integration. Ideal for agents that need on-demand drug information with microtransaction billing via USDC on Base, rather than a subscription or self-hosted API key setup. Best when querying individual drugs by name in an automated pipeline.

## Known failure modes

- Drug not found in OpenFDA database — returns empty results or 404
- Invalid or misspelled drug name query — may return no matches
- OpenFDA API upstream downtime — service may be temporarily unavailable
- Payment failure via x402 — call not executed if USDC payment not settled
- Rate limiting or quota exceeded on upstream OpenFDA API

## How this service works

Pay-per-call crypto, RWA, federal, SEC, and compliance APIs. Settled in USDC on Base via x402. Hyphen routes only (e.g. /x402/rwa-aggregates, /x402/gas-tracker).

## Output

Returns FDA drug label data for the queried drug, including fields such as indications and usage, warnings, contraindications, dosage and administration, adverse reactions, drug description, and active/inactive ingredients, sourced directly from OpenFDA.
