LEI checksum is arithmetic; it does not prove ISSUED in GLEIF. Lookup calls GLEIF. A valid UUID structure does not prove a particular issuer.

Which endpoints?

POST /v1/id/lei (checksum) · /v1/id/lei/lookup (GLEIF) · /v1/id/uuid — idle $0; lookup hits upstream + cache.

Is LEI checksum a GLEIF registration?

No. /v1/id/lei is ISO 7064 arithmetic only. Use /v1/id/lei/lookup (GLEIF) for registration status.

Free vs paid?

The playground is an anon IP demo quota. A paid API key is for software integration, higher quotas and call metering. Idle $0.
