GetAPIclaude-opus-5 API: billing and integration
Compare models, explore supported endpoints and check current pricing before integrating.
Model identifier
claude-opus-5 Model overview
Claude Opus 5 is positioned for deep reasoning, complex agentic coding and long-horizon work. Its official API uses adaptive thinking with model-specific effort controls.
Tasks to evaluate
- Evaluate engineering tasks that combine planning, implementation and verification.
- Work through multi-stage analysis with explicit intermediate outputs.
Integration notes
Do not copy thinking settings unchanged from older models. Check which effort and tool fields your GetAPI protocol accepts.
Based on provider documentation, not a GetAPI execution test. Supported request fields and limits depend on the selected endpoint.

Before your first request
- Confirm the exact model identifier and supported endpoint.
- Create a server-side API key with the required permissions and quota.
- Match the model endpoint type to a compatible request protocol before sending traffic.
A model listed by the gateway is not automatically compatible with Codex. Use its declared endpoint as a starting point, then confirm request fields and billing before testing.
