type: Conformance
generated: '2026-09-15'
method: derived
source: Assessed against the Teler OpenAPI (api.frejun.ai/openapi.json) and public docs signals.
conformance:
- id: oauth2
  conforms: false
  evidence: The API authenticates with an x-api-key header; no OAuth2 securityScheme is declared.
- id: oidc
  conforms: false
  evidence: No OpenID Connect surface on the API.
- id: rfc9457
  conforms: false
  evidence: >-
    Errors use a custom {success,message,code,type} JSON envelope, not
    application/problem+json / RFC 9457.
- id: rfc8594-deprecation
  conforms: false
  evidence: One operation is marked deprecated in the spec, but no Sunset/Deprecation response headers are declared.
- id: cursor-pagination
  conforms: true
  evidence: >-
    All list endpoints use consistent cursor pagination
    (cursor_after/cursor_before/limit; next_cursor/previous_cursor/has_more).
- id: sip
  conforms: true
  evidence: >-
    The provider exposes programmable SIP trunking (SIP / Trunks, SIP / Calls,
    SIP IP ACLs) — SIP is the telecom signaling protocol, exercised via the REST
    control plane. This is a protocol capability, not a machine-readable
    domain-standard contract signature.
domain_standard:
  present: false
  note: >-
    No domain-standard signature (SCIM URN, OData $metadata, OpenRTB, HL7/X12,
    ISO 20022, etc.) is declared in the contract. The CPaaS/voice market has no
    single REST domain standard, so none is asserted (reward-only dimension).
