# NHTSA Vehicle Safety Recalls Change Feed

> NHTSA Vehicle Safety Recalls Change Feed is a paid API for AI agents from oracles-production.up.railway.app, paid per call via x402, $0.05/call, status unknown (last checked 2026-09-15).

Returns newly detected NHTSA vehicle safety recalls for popular models, with severity flags, affected component, consequence, and remedy details.

## Facts

- Endpoint: GET https://oracles-production.up.railway.app/v1/nhtsa-recalls/changes
- Price: $0.05/call
- Payment: x402
- Status: unknown

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 nhtsa-vehicle-safety-recalls-change-feed-0680ff51
```

Example prompt: Show me any new NHTSA vehicle safety recalls detected since January 1, 2025 with a significance of at least 7 — especially anything with a park-it or park-outside warning, up to 50 results.

## When to prefer this

Use this endpoint when you need a structured, filtered feed of newly detected NHTSA vehicle safety recalls with severity triage (park-it/park-outside flags) and significance scoring. Prefer it over raw NHTSA API calls when you want change-detection semantics (only new items since a timestamp), pre-computed severity flags, and a pay-per-call model without managing API keys.

## Known failure modes

- No recalls found matching the since/min_significance filters returns an empty changes array
- Invalid date-time format for 'since' parameter causes a 400 validation error
- Limit out of range (below 1 or above 500) causes a 400 validation error
- Payment not provided or invalid results in a 402 Payment Required error
- Service temporarily unavailable returns a 5xx error

## How this service works

NHTSA vehicle safety recalls for a curated set of popular models, with severity flags (park-it, park-outside), affected component, consequence, and remedy.

## Output

A JSON object containing a count of changes, a source identifier, and an array of recall change objects. Each change includes a title, type, summary, detailed recall info (affected component, consequence, remedy, severity flags like park-it/park-outside), significance score (1–10), entity ID, source URL for verification, detected-at timestamp, and optional effective date.
