  version: v1
  summary: Optical lab ordering API for eyewear prescriptions, lens catalogs, and orders.
  description: SpecCheck is an optical lab ordering platform. Its REST API lets eyecare practices and partners look up the labs and lens catalogs available to a user, retrieve a lab's order settings, and create prescription (rx), frame, and multi-pair orders programmatically. Authentication uses a bearer token obtained from client credentials, plus a `User-Email` header identifying the acting SpecCheck Dashboard user. POST requests support an `Idempotency-Key` header for safe retries. This specification was reconstructed by API Evangelist from SpecCheck's public documentation at https://docs.speccheckrx.com and is not an official SpecCheck artifact.
