# Drug Safety Card: FDA Labels, Interactions & Harm Reduction

> Drug Safety Card: FDA Labels, Interactions & Harm Reduction is a paid API for AI agents from apexfaucet.xyz, paid per call via x402, $0.005/call, status unknown (last checked 2026-10-01).

Returns a comprehensive drug safety card for any drug name or substance, combining FDA label warnings, adverse-event counts, recalls, molecule facts, and harm-reduction dosage information in a single call.

## 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 drug-safety-card-fda-labels-interactions-harm-reduction-b32196c1
```

Example prompt: Pull up a full drug safety card for ibuprofen — I need the FDA boxed warnings, any contraindications, known drug interactions, recent recalls, and harm-reduction dosage facts all in one shot.

## When to prefer this

Choose this endpoint when you need a comprehensive, multi-source drug safety profile in a single API call rather than querying FDA, RxNorm, ChEMBL, and harm-reduction databases separately. It is especially valuable for agents handling medication safety checks, drug interaction screening, or harm-reduction guidance for both prescription drugs and recreational substances. Prefer it over individual FDA API calls when you need adverse-event counts, recalls, molecule data, and label warnings aggregated and labelled with sources simultaneously.

## Known failure modes

- Drug name not found in RxNorm — returns an error or empty normalization result
- Obscure or misspelled drug name fails RxNorm lookup
- No FDA adverse-event data exists for the substance (e.g., novel or uncommon compounds)
- No recent recalls found — returns empty recall list rather than an error
- Payment failure (HTTP 402) if USDC payment is not attached or insufficient
- Harm-reduction data unavailable for prescription drugs not tracked by harm-reduction sources

## How this service works

Drug safety card: FDA label warnings, adverse-event counts, recalls, molecule and harm-reduction facts, each with its licence. Drug safety card from open sources in one call: pass ?name=ibuprofen (brand or generic) or a substance such as MDMA. RxNorm normalises the name to its ingredients; then the FDA label warnings (boxed warning, contraindications, interactions), FDA adverse-event report counts with the top reactions, recent FDA recalls, molecule facts (ChEMBL) and harm-reduction dose…

## Output

A structured drug safety card containing: FDA boxed warnings, contraindications, drug interactions section from the label, FDA adverse-event report counts with top-ranked reactions, recent FDA recall notices, ChEMBL molecule facts, and harm-reduction dosage guidance — each item attributed with its data source and licence.
