note: >-
Derived from the Later Influence (formerly Mavrck) Swagger 2.0 contract published at
https://api.mavrck.co/api-docs, then confirmed against live unauthenticated probes of
https://api.mavrck.co/v1/*. The contract declares ONE security definition (an `api-key`
header) but the operation descriptions and the live 401 bodies show a SECOND, distinct
credential in use on the influencer-facing surface: a JWT minted by the /email-auth,
/api-key/facebook and /auto-login operations and sent on subsequent requests. Later
publishes no public developer portal for either surface, so no docs URL upgrades this
to method searched.

gaps:
- The contract declares no oauth2, openIdConnect or mutualTLS scheme, so no OAuth scope
reference can be derived; scopes/ is intentionally absent.
- The JWT credential is used but undeclared in `securityDefinitions`, so a generated
client will not send it.
- No public credential-provisioning documentation is published on later.com; api-key
issuance appears to be account-managed.
