Example prompt: Can you look up EPA Toxics Release Inventory facilities in New Jersey, specifically in Newark — show me up to 20 results with their TRI IDs, addresses, and parent companies?

## When to prefer this

Use this endpoint when you need structured EPA TRI facility data searchable by US state and city — especially for environmental research, compliance audits, due diligence, or investigative tasks. Prefer it over general web search when you need machine-readable facility records with TRI IDs, parent company linkages, and closure status from the official EPA dataset.

## Known failure modes

- Missing required 'state' parameter returns validation error
- Invalid or non-existent state code may return empty facility list
- City name misspellings may return zero results
- Limit value outside 1-50 range may be rejected or clamped
- Payment failure (x402) blocks access to results
- EPA TRI data may be outdated or incomplete for recently opened/closed facilities
