max_tokens or max_completion_tokens?
OpenAI-compatible APIs do not share one output-token rule. Ark documents both fields separately and forbids using them together; Groq and Kimi mark max_tokens deprecated. Other route rules stay unverified until the exact provider documentation establishes them.
Check a request body
Choose the exact route, then paste the JSON body. This page checks field names only; it does not send a request.
Select a provider route before checking fields.
Only top-level max_tokens and max_completion_tokens keys are compared. Values, nested properties, headers and the rest of the request are not checked. JSON.parse collapses duplicate object names, so raw duplicate counts are unavailable.
Compare the exact provider route
Each row keeps the model ID, endpoint, region or plan together. A missing example is not evidence that a field is rejected.
| Provider route | max_tokens | max_completion_tokens | Both fields | Evidence |

“Documented” means the field appears in the cited route source. It does not mean every value, model feature or full request is supported. “Not verified” means this review found no exact-route rule; it does not mean unsupported.
