AI Humanizer API

For free, you will receive 500 free trial credits with the sandbox and you only need to enter payment information to activate it. These credits are perfect for submitting humanize endpoint requests to test your production integration.

The humanize endpoint is a sync endpoint which means you will get a completed rewrite request response in the same record. The API will not return a value until a response is ready. There is no polling endpoint, job queue, or webhook needed.

The rewrite style for each content type is controlled by the purpose. These adjustments can be made for general or formal writing, for example. Sentence complexity is controlled by adjusting readability in the output. Detection bypass controls how aggressive the rewrite is optimized against AI detection.

In the case a request exceeds the rate limit, a rate limit error will be returned instead of the request being queued, as is the default in most cases. Please consider your plan's concurrency and RPM limits and add retry logic with backoff in the case you are expecting bursty traffic.

Not exactly. Our humanizing API doesn’t guarantee a permanent pass against popular AI detector APIs on the market, since AI detection models also keep updating. The detection_bypass parameter helps you reduce that risk but not eliminate it. Therefore, you can treat it as a mitigation, not a guarantee.

Yes, of course. Structural elements like markdown formatting and line breaks in the input carry through to the output field. Therefore, you don’t have to rebuild formatting after the call returns.
