    "description": "Public API for East End Business Services (eebs.us). Versioned by URL path (/api/v1/, /api/v2/, ...). The current version is v1, exposed under /api/v1. The unversioned /api/* paths are deprecated aliases kept working for backward compatibility; every response from a deprecated path carries an RFC 8594 `Deprecation: true` header and a `Link` header with `rel=\"successor-version\"` pointing at its versioned replacement. A `Sunset` header will be added once a removal date for a deprecated path is scheduled — none is scheduled today. See the developer portal at https://eebs.us/developers for a quickstart.\n\nRate limiting: /api, /api/v1, /api/contact, /api/v1/contact (all methods), the homepage, and any 404 are limited to 120 requests per 60-second window per client IP, tracked in a fixed window. Every response on those paths carries `RateLimit-Limit`, `RateLimit-Remaining`, and `RateLimit-Reset` (seconds until the window resets), per the conventions in draft-ietf-httpapi-ratelimit-headers, including error responses. A request over the limit gets `429` plus `Retry-After` (seconds). No authentication is required — the limit is per IP, not per key — and no API key exists to raise it; see /developers.",
