Spin Rewriter publishes an API for developers and automation workflows. Its current documentation says requests are sent by HTTP POST and responses are returned as JSON.

Current documented actions

api_quota — check remaining API calls.
text_with_spintax — process text into spintax.
unique_variation — request a unique variation of supplied text.
unique_variation_from_spintax — generate a variation from existing spintax.

Request limit

The current API help page states a limit of up to 500 API requests per day. The merchant also provides sample code and SDK/package options for PHP, Python, JavaScript and C#.

Who should care?

The API is relevant if rewriting needs to happen inside another application or publishing workflow rather than through the Spin Rewriter web interface.
