EPA Facility Compliance Lookup via x402 Micropayment

Use this endpoint when you need programmatic, pay-per-call access to EPA Facility Registry Service compliance data keyed by geographic coordinates, street address, facility name, or registry ID. Prefer it over scraping EPA web interfaces when you need structured JSON output suitable for automated workflows, due diligence pipelines, or compliance screening at scale. The x402 micropayment model ($0.026/call) makes it suitable for low-to-medium volume lookups without subscription overhead.

• No facility found matching the given name, coordinates, or address — result may be empty
• Invalid or out-of-range coordinates (lat outside [-90,90] or lon outside [-180,180])
• Address geocoding failure if the street address is malformed or outside the US
• EPA FRS Registry ID not recognized — returns empty or error result
• Missing required parameters (type and method must be present in input object)
• Payment failure or insufficient USDC balance — 402 response blocking access
