You are integrating the Long Strange Click API, a read-only JSON API over a frozen,
canonicalized Grateful Dead live-performance catalog.

1. Fetch https://staging.longstrangeclick.com/llms.txt and read it end to end before writing any code.
   It lists every endpoint, the response envelope, and the rate limit.
2. Fetch https://staging.longstrangeclick.com/openapi.json (or /openapi.yaml) for the machine-readable
   contract, or import https://staging.longstrangeclick.com/postman.json into Postman to explore it.
3. No authentication is required. Every response is the canonical
   { data, meta } envelope; read your rows from `data`.
4. The surface is IP rate-limited to 100 requests per
   60s (burst), plus a daily quota of
   250 requests per IP; a request must pass both.
   Read the RateLimit-Remaining and RateLimit-Reset response headers and
   back off before you are throttled; on a 429, honor the Retry-After header
   rather than retrying immediately.
5. Resolve an external Grateful Dead URL (archive.org, setlist.fm, ...) to a
   canonical show with GET /api/v1/resolve-url?url=...; look up a specific
   date with GET /api/v1/shows/date/{date} (a date may hold more than one
   show for early/late sets).
