Access model

Open web, Free account, and Pro solve different jobs.

The website exposes a six-month public view through its protected gateway. Direct API access always requires an account-owned key.

Capability	Open web	Free account	Pro
Authentication	No direct API access	API key	API key
Rate-limit identity	Website gateway	Account key	Account key
Issuer scope	Public browsing	One pinned issuer	All available issuers
Usage ledger	Not account-scoped	Included	Included

Trust boundary

Normalized for analysis, traceable to the authority.

OpenInsider creates stable entities and fields without pretending the normalized record replaces its regulatory source.

Build the first request, then inspect the full contract.

Sign in to create an account-scoped key, or join the waitlist if registration is not yet available to you. Swagger and the OpenAPI JSON remain the authoritative operation and schema references.
