Blameless
The Blameless platform API — incidents, incident types, severities, roles, SLOs, SLIs and error budgets — served per tenant at https://{instance}.blameless.io/api/v1 with Auth0 client-credentials bearer tokens. Retired: no tenant host resolves as of 2026-08-29 and the reference at docs.blameless.com has been removed. No OpenAPI, AsyncAPI or GraphQL contract was ever published. Documented here from Blameless' own open-source client code and its live Auth0 discovery document.
