  version: 1.0.0

x-generated: '2026-08-23'
x-method: generated

  API Evangelist annotations derived from the harvested spec and Justt's published
  alerts documentation. The original spec is not mutated.
actions:
- target: $.info
  update:
    x-apievangelist-profile: https://apis.io/provider/justt
    x-apievangelist-discovery: >-
      This definition is not linked from Justt's getting-started page. It was found
      via the RFC 9727 linkset at https://developers.justt.ai/.well-known/api-catalog.
    x-apievangelist-conventions: conventions/justt-conventions.yml
    x-apievangelist-related-write-operation: >-
      PreChargebackAlertsController_createOutcome lives in the REST API spec, not
      here — reading alerts and reporting their outcome are split across two
      definitions.
- target: $.servers
  description: >-
    The published servers array carries a development entry pointing at localhost,
    which is not a callable host for any consumer.
  update:
    x-apievangelist-note: >-
      servers[1] is http://localhost:3075/v1 ("Development server"). Clients must
      select the production server https://api.justt.ai/v1 explicitly. Leaving a
      localhost server in a published contract is a defect worth reporting.

- target: $.paths['/pre-chargeback-alerts/alerts'].get
  update:
    x-apievangelist-realtime-alternative: >-
      Justt supports push notification of alerts in real time (contact the account
      manager) and emits the pre_chargeback_alert.received webhook. Prefer either
      over polling — alerts are time-critical.
