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 stratalize-openfda-adverse-events-signal-0f8973c4
```

Example prompt: Pull the FDA FAERS adverse event signal for Ozempic — I need the total reports, deaths, hospitalizations, top reactions, and the overall signal level (HIGH, ELEVATED, MONITOR, or LOW).

## When to prefer this

Use this endpoint when you need a structured, pre-computed FDA drug safety signal with severity classification rather than raw FAERS data. Ideal when you need a quick HIGH/ELEVATED/MONITOR/LOW signal label alongside key statistics in one call. The cryptographic signing and independent verifiability via ML-DSA-65 make it suitable for compliance, audit, or trust-sensitive contexts where data provenance must be confirmed.

## Known failure modes

- Unknown or misspelled drug name returns no data or empty result
- Drug with very few FDA reports may return LOW signal with limited reaction data
- OpenFDA upstream API unavailability may cause timeout or error response
- Invalid input format (non-string drug_name) returns validation error
- Payment failure via x402 protocol returns 402 Payment Required before data is returned

## How this service works

Stratalize — attested finance, legal, healthcare, and compliance intelligence. Signed, independently verifiable receipt on every call (trust.stratalize.com/verify). FDA FAERS adverse event signal for a drug — total reports, serious events, deaths, hospitalizations, top reactions with percentages, and signal level (HIGH / ELEVATED / MONITOR / LOW). Source: OpenFDA

## Output

Returns total adverse event report count, count of serious events, deaths, and hospitalizations, a list of top reactions with percentage breakdowns, a signal classification (HIGH/ELEVATED/MONITOR/LOW), plus an ML-DSA-65 cryptographic signature and a verifiable receipt URL at trust.stratalize.com/verify for independent verification of the data.
