  "raw_analysis": "ECHO (Enforcement and Compliance History Online) is a public-facing web platform maintained by the U.S. Environmental Protection Agency's Office of Enforcement and Compliance Assurance (OECA). It aggregates compliance, inspection, violation, and enforcement data across multiple environmental statutes including the Clean Air Act, Clean Water Act, Resource Conservation and Recovery Act, and Safe Drinking Water Act.\n\nPrimary audience: general public, researchers, journalists, regulated entities, environmental advocates, and government staff seeking transparency on environmental enforcement.\n\nMaturity: Established government tool with years of operation; highly mature and authoritative data source. Data is sourced from EPA's Integrated Compliance Information System (ICIS) and other agency databases.\n\nThe provided URL points to a contact/general info page, not an API documentation page. While ECHO is primarily a web application without a prominent public REST API, the EPA does expose some supporting services (e.g., EPA Envirofacts API, ECHO data downloads via CSV/Excel exports). The platform itself functions as a data exploration and reporting tool rather than a developer API product.\n\nIntegration notes: Data is available through bulk downloads and the broader EPA Envirofacts/Open Data ecosystem. No authentication is required for public access. Rate limits are not publicly specified; usage is subject to standard government website acceptable-use policies.\n\nPricing: Fully free as a taxpayer-funded public service. No commercial tier."

  "issues": [
    "No llms.txt (404) — agents lack a structured machine-readable entry point.",
    "Primary interface is web UI; public JSON/REST API surface for ECHO is limited (mostly downloadable files/envirofacts).",
    "No explicit 'Sign in with Notlogin' or magic-link flow; some features gated behind account creation."
  ],
  "recommendations": [
    "Publish an llms.txt describing key endpoints, datasets, and query patterns for agent consumption.",
    "Expose a documented JSON API with stable schemas for facility, compliance, and enforcement queries.",
    "Support magic-link or verified-identity auth (e.g., Notlogin) to reduce onboarding friction.",
    "Provide OpenAPI spec and example queries to improve first-try success.",
    "Add status page / uptime API to strengthen reliability signals."
