## 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 sitecheck-api-us-regulatory-violations-lookup-osha-epa-ae02d07f
```

Example prompt: Pull up any EPA or OSHA violations for Chevron Phillips in Texas since January 2022 — I want to see fines over $100,000.

## When to prefer this

Use this endpoint when you need to quickly look up US federal regulatory enforcement records (OSHA workplace safety or EPA environmental violations) for a specific company or across a state, without needing to sign up for an API key. It is ideal for due diligence, compliance research, supplier vetting, or investigative journalism workflows where pay-per-call access to OSHA and EPA ECHO data is sufficient. Prefer this over manual government portal searches when automation or agent integration is required.

## Known failure modes

- Company name not found — returns empty results array with total: 0
- OSHA data unavailable if DOL_API_KEY is not configured — only EPA results returned with a notes warning
- Invalid state code — may return no results or an error
- Date format not in YYYY-MM-DD — may cause a query error
- limit out of range (must be 1-100) — may return an error
- Payment failure via x402 — request rejected before processing

## How this service works

Pay-per-call tools for AI agents: image generation, speech-to-text, text-to-speech, embeddings, LLM chat, website audits and contact enrichment, web page to Markdown reader, PDF to text, sitemap URLs, tech stack detection, translation, exchange rates, e-mail pre-check, domain RDAP/DNS lookup, Solana token checks, trending tokens and wallet holdings, plus business and compliance data (EU VAT/VIES, IBAN, LEI/GLEIF, US recalls, OSHA/EPA violations, UK insolvency notices). Plus prediction-market search, briefs, quotes and unsigned buy transactions, powered by Panta. Payment: x402, USDC on Base, Solana or Arc. No signup, no API key.

## Output

Returns a JSON object containing a results array of enforcement records, each with case ID, company name, facility, city, state, violation type, date, penalty amount in USD, case status, source (OSHA or EPA), and a link to the full enforcement case report. Also includes total count, the echoed query parameters, caveat text about public records interpretation, and a list of data sources used.
