# Drug Safety & FDA Brief

> Drug Safety & FDA Brief is a paid API for AI agents from agent-data.centorprat.workers.dev, paid per call via x402, $0.03/call, status unknown (last checked 2026-10-29).

Fuses four openFDA data sources (approvals, FAERS adverse events, recalls, and boxed warnings) into a single composed safety brief for up to two drugs per call

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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-fda-brief-6285423d -d '<json body>'
```

Example prompt: Pull me a full FDA safety brief for ozempic — I want the approval status, top FAERS adverse reactions, any recalls, and whether there's a boxed warning.

## When to prefer this

Use this endpoint when you need a comprehensive, multi-source FDA safety snapshot for one or two drugs in a single call. It is preferred over querying openFDA directly because it fuses four data sources (approvals, FAERS, recalls, boxed warnings) into one response without requiring an API key. Ideal for pre-prescribing research, patient safety checks, or regulatory due diligence workflows where speed and completeness matter more than raw data access.

## Known failure modes

- Drug name not found in any openFDA source — lookup fails gracefully with an error indicator for that drug
- More than 2 drugs submitted — rejected by input schema (maxItems: 2)
- openFDA upstream API timeout or unavailability — may return partial or error response
- Misspelled or highly obscure drug names may yield no results

## How this service works

Pay-per-call data and tools for AI agents, $0.002-0.01 per call in USDC via x402 (Base, Polygon or Solana), no account or API key; MAX tiers ($0.05-0.25) run deeper jobs. Agent toolkit: web search, search + read top pages, any page as clean markdown with a prompt-injection check, which-x402-API-to-call recommender, seller check. Data: Google Maps places with contacts, YouTube video data and transcripts, job listings (Indeed, LinkedIn, 13 boards), Google Ads Transparency, TikTok comments, Pinterest, Airbnb, Redfin, AliExpress, app stores, live sports, website and SEO checks, Shopify store tech stacks, and onchain token / address risk checks.

## Output

A structured safety brief per drug containing: FDA approval status, total FAERS adverse event reports, top reported reactions, count of serious events, count of deaths, active recall information, and full boxed warning text if present. Failed lookups are indicated but not charged.
