ROLLIN API reference.

REST API over HTTPS. JSON request and response bodies. Authentication via the X-Api-Key header. Eight endpoints. Free tier covers 1,000 requests per month with no credit card. Starter tier ($9.99/mo) unlocks full address precision, photos, hours, and 5,000 monthly requests.

Base URL: https://joinrollin.com/api/v1. Full OpenAPI 3.1 spec at /openapi.yaml.

Authentication

Send your API key in the X-Api-Key header on every request. Keys start with a tier prefix: rlf_ (free), rls_ (starter), rld_ (developer), rlb_ (business), rle_ (enterprise).

curl -H "X-Api-Key: $ROLLIN_API_KEY" "https://joinrollin.com/api/v1/health"

A missing or invalid key returns 401 Unauthorized. A revoked or expired key returns 403 Forbidden.

Errors

Errors return standard HTTP status codes with a JSON body of the form { "error": { "code": "…", "message": "…" } }.

Rate limits

Per-minute and per-month limits scale with tier. Hitting a limit returns 429 with a Retry-After header (seconds). The /v1/health endpoint is unauthenticated and uncounted.

Pagination

List endpoints accept a limit parameter (default 20, max 100) and return a next_cursor field when more results are available. Pass the cursor back as cursor to fetch the next page.

Search venues by location, query, or both. Results are pre-sorted by accessibility score, descending.
