Authentication & Security 2

Cubist Signing API declares 2 security schemes for authenticating requests. An API key is passed in the header as Authorization (Oidc). An API key is passed in the header as Authorization (SignerAuth). By default, every request must be authenticated.

  • Oidc — OIDC tokens allow users to authenticate using a third-party service. These are exchanged for signer session tokens.
  • SignerAuth — Signing API end-points use session tokens for auth. Specifically, with each request you need to use the \token\ from your signer session (which you create with…

Where this information came from

This is an independent, third-party profile of Cubist Signing API, published by API Evangelist. We do not operate, host, resell, or support these APIs, and we are not affiliated with or endorsed by the company unless stated above. Everything here is built from publicly available information — the company's own site, developer portal, documentation, public repositories, and the specifications it publishes for public use. Nothing is obtained by breaching a system, defeating an access control, or using credentials.

The Kin Score and Agent Readiness rating are independently calculated assessments of a company's public API artifacts, scored against a published rubric. They are not certifications, endorsements, security assessments, or audits.

Corrections, re-scores, and removal are free — no partnership or purchase required, and you do not need to justify the request. A removed company is recorded as unrated, never scored zero for having asked. Acknowledgement within one business day; removal within two.
