What every SDK gets you
-
Generated from the spec
Every method, parameter, and response model is generated from
vendor/api-specs/v2.2.json. The SDK shape matches the wire shape one-to-one. -
Bearer auth, sane defaults
Pass your 32-character API key once at construction. The SDK injects
Authorization: Bearer <key>on every request; the key never appears in logs or error output. -
Typed errors, not strings
Distinct exception or result types for transport failures, 4xx client errors, 5xx server errors, and rate-limit responses. Branch on the type, not on the message text.
-
All 74 operations covered
Every operation in v2.2.10 is reachable from every SDK. No "supported in Python but not Go" gaps. CI runs the full operation matrix per release.
