Keys are created in the dashboard and scoped to one workspace. **Pagination** is cursor-based. Pass `next_cursor` back as `cursor` and stop when `has_more` is false. The cursor is opaque; do not parse it. **Dates** are ISO 8601. `from` is inclusive, `to` is exclusive. Omitting both gives the last 30 days. **Limits** exist to stop runaway clients, not to meter you: there is no monthly request ceiling. Every response carries `X-RateLimit-*`, and endpoints that spend money carry `X-Endpoint-*` as well. A 429 names which limit was hit. **Errors** always carry a stable `error.code`. Match on that, never on the message text. A verb that an endpoint does not declare returns 405 `method_not_allowed`. contact: name: Geoptie support email: support@geoptie.com servers: - url: https://api.geoptie.com description: Production security: - bearerAuth: [] tags: - name: Brands description: The brands you track.
