Spin Rewriter API Guide

Spin Rewriter’s API extends rewriting into custom applications and workflows, but successful automation still needs safeguards around meaning and output quality.

Updated September 9, 2026

The 500-request daily limit was checked against official Spin Rewriter documentation on September 9, 2026.

What the API currently supports

The official API documentation lists actions for checking quota, returning processed text with spintax, producing a unique variation, and producing a unique variation from existing spintax. Requests use HTTP POST and responses are returned as JSON.

Current daily limit

The product documentation currently states a maximum of 500 API requests per day. Treat that as a live product limit rather than a permanent architectural assumption.

Good integration patterns

What to validate

Test failure handling, quota behavior, encoding, long inputs, protected terms, and the human-review step. A technically valid response says nothing about whether the rewritten text is accurate or appropriate to publish.
