Detector-aware API

Ship the same review loop users see in the app.

The API is not a single text rewrite endpoint. It exposes the practical workflow: transform a draft, scan AI-like signals, keep source metadata, and route users toward the next revision.

Core endpoints

One API surface for the writing workflow.

The public API mirrors the product: lower AI-like phrasing, run AI Detector scans, rewrite passages, and keep citation work in the same account.

POST

/api/v1/humanize

Humanize text

Lower AI-like phrasing while preserving meaning, names, citations, and structure.

POST

/api/v1/paraphrase

Paraphrase & polish

Rewrite in standard, fluency, formal, academic, simple, creative, expand, or shorten modes.

POST

/api/v1/rewrite

Academic rewrite

Use the focused academic polish workflow for cleaner structure and sentence flow.

POST

/api/v1/detect

AI detector

Return review estimates, writing signals, source notes, and revision guidance.

POST

/api/v1/citation

Citation format

Format DOI, URL, web, book, journal, and manual source metadata.

POST

/api/v1/bibliography

Bibliography

Sort and format citation lists with HTML, text, BibTeX, and RIS output.

GET

/api/v1/status

Key status

Check key name, word balance, request limits, created time, and last use.

Create key

Generate a workspace API key and copy it once.

Send request

Call /api/v1 endpoints with a Bearer token and JSON payload.

Track usage

Requests are logged with words, endpoint, status, and owner.

Control billing

Plan limits, checkout, portal routing, and webhooks are ready for live Stripe keys.

Request lifecycle

Built for keys, limits, and usage review.

The Stripe and Google secrets stay configurable, but the product surface is already shaped around account-owned keys, metered calls, and workspace review.

API billing

Meter usage like a product surface, not a black box.

Every API call stays tied to a workspace, key, endpoint, status code, and word count. That gives teams a clear path from first test request to production usage review.

Workspace balanceStatus endpointUsage ledgerStripe-ready plans

Shared word balance

Account-owned

Transform and detector endpoints deduct words from the same workspace balance after a successful result.

Failed request behavior

No output, no charge

Auth errors, validation errors, insufficient balance, and processing failures return JSON errors before credits are consumed.

Volume path

Pro and Business

Use the workspace for API keys and plan status, then contact support for higher limits, partner traffic, or volume review.

Frequently asked

Developer questions before the first deploy.

The API follows the same product boundary as the app: account-owned keys, explicit language handling, clear limits, and response metadata that clients can show back to users.

01How does API billing work?

API calls use the word balance attached to the workspace owner. Successful humanize, paraphrase, rewrite, and detector requests deduct the input word count; citation and bibliography calls are logged separately.

02When are words deducted?

Words are deducted after the endpoint returns a successful processed result. Invalid API keys, malformed bodies, rate-limit errors, insufficient balance, and processing errors do not consume the requested words.

03How many keys can a workspace create?

The v1 workspace supports up to five active API keys, so production, staging, partner, and internal automations can be separated and revoked independently.

04Which languages does the API process?

The writing logic is designed around English, Simplified Chinese, and Traditional Chinese processing. The API accepts a language field so clients can keep processing behavior explicit.

05What should developers build first?

Start with /api/v1/status to verify the key and balance, then send a small /humanize or /detect request before wiring larger editor, LMS, extension, or CMS workflows.
