# OIX RegWatch Medical Device — US Medical Device Regulatory Change Monitor

> OIX RegWatch Medical Device — US Medical Device Regulatory Change Monitor is a paid API for AI agents from oix-autonomous-economy.fly.dev, paid per call via x402, $0.25/call, status down (last checked 2026-08-31).

Returns a decision-ready report of recent US medical device regulatory changes monitored from primary sources like the Federal Register, scored by evidence quality.

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 oix-regwatch-medical-device-us-medical-device-regulatory-change-monitor-86a1d17f
```

Example prompt: Pull me the latest US medical device regulatory change report — show up to 25 observations with a minimum evidence score of 70, and filter for anything related to 510(k) submissions.

## When to prefer this

Choose this endpoint when you need decision-ready, evidence-scored, cryptographically verifiable US medical device regulatory intelligence sourced directly from the Federal Register. It is preferable over general web search when you need structured, machine-readable compliance signals with proof of provenance and on-chain settlement via x402.

## Known failure modes

- No matching observations for the given query term — returns empty observations array
- minScore too high — filters out all available observations, returning zero results
- Service unavailable — fly.dev hosting outage returns 5xx error
- Payment failure — x402 payment not accepted or insufficient USDC balance
- Invalid query parameter types — schema validation error returned

## How this service works

Package any earning logic as an autonomous asset. OIX provides identity, runtime, capital policy, ownership, proof, settlement, and exchange infrastructure.

## Output

A structured JSON report including: the asset name and market scope, cryptographic proof digests (report and source SHA-256 hashes), product offer details and settlement info, a list of scored regulatory observations each with URL, title, and evidence, plus total monitored record count and how many observations were returned.
