# NHTSA ODI Investigations Feed

> NHTSA ODI Investigations Feed is a paid API for AI agents from 2s.io, paid per call via x402, $0.0024/call, status unknown (last checked 2026-09-14).

Returns a chronological feed of NHTSA Office of Defects Investigation (ODI) records — preliminary evaluations, engineering analyses, defect petitions, and recall queries — newest first, with optional open/closed status filtering.

## Facts

- Price: $0.0024/call
- Payment: x402

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 2s-io-00d2f2af
```

Example prompt: Pull the 50 most recent open NHTSA ODI investigations — I want to see what defects and safety probes the government is currently running, including preliminary evaluations, engineering analyses, and recall queries.

## When to prefer this

Use this endpoint when you need a broad, chronological view of all active or recent NHTSA defect investigations across all makes and models. Prefer this for monitoring regulatory activity, tracking what NHTSA is currently probing industry-wide, or building feeds of government safety actions. Do NOT use this for vehicle-specific recall or complaint lookups — use vehicle.recalls or vehicle.complaints for those.

## Known failure modes

- Invalid status value (not 'O' or 'C') returns a 400 error
- Offset exceeding 10000 returns an error
- Limit outside 1–100 range returns a validation error
- NHTSA upstream data temporarily unavailable may cause 502/503
- No results returned if no investigations match the status filter at that offset

## How this service works

Chronological feed of NHTSA ODI (Office of Defects Investigation) investigations, newest first. Returns preliminary evaluations (PE), engineering analyses (EA), defect petitions (DP), and recall queries (RQ) — each with NHTSA ID, type code, open/close dates, status, subject, and full description (HTML stripped + raw). Useful for tracking what NHTSA is currently investigating (Tesla FSD, autonomous-vehicle crashes, Rivian suspension, etc.). NOTE: NHTSA's endpoint does NOT support make/model/year filtering — use vehicle.recalls or vehicle.complaints for vehicle-scoped lookups. Public-domain US government records.

## Output

Returns a paginated list of NHTSA ODI investigation records, each containing NHTSA investigation ID, investigation type (PE/EA/DP/RQ), open and close dates, current status (open or closed), subject line, and full description with HTML stripped and raw versions. Records are ordered newest first.
