Isometric Registry API
The Registry API exposes Isometric's public carbon removal registry — issuances, credit batches, organization credit balances, transfers, retirements, refunds, orders, deliveries, projects, suppliers, and project documents — alongside transactional operations to create transfers, retirements (including retire-from-oldest-credits), deliveries, beneficiaries, and Stripe checkout sessions. Operates against /registry/v0 on both sandbox and production environments using bearer + x-client-secret authentication. Includes 38 paths and 79 schemas. Already consumed by CDR.fyi, MSCI, Sylvera, and CEEZER for real-time CDR market data.
