Start from the workflow you need

Developer hub

Production path

Create a key, call the endpoint, track usage.

TurnitPass keeps the developer path close to the product workflow: account-owned keys, metered requests, word balance, and docs that map to live routes.

Create API key

Generate a named key from the workspace and copy it once.

Send Bearer request

Call humanizer, detector, paraphrase, citation, or bibliography routes.

Review usage

Requests roll up to word balance, endpoint logs, and future billing limits.

Humanizar

POST/api/v1/humanize

Reduz os sinais de escrita por IA enquanto preserva o significado original.

Parafrasear

POST/api/v1/paraphrase

Reescreve e refina textos em múltiplos modos.

Detectar

POST/api/v1/detect

Retorna pontuação estimada, nível de risco e sinais de escrita.

Citações

POST/api/v1/citation

Formata metadados de fontes DOI, URL ou inseridos manualmente.

Use cases

What developers are building

The API is designed around the same TurnitPass workflow writers use in the browser: humanize, detect, rewrite, paraphrase, cite, and track usage.

01POST /api/v1/humanize

Content platforms

Humanize AI-assisted drafts before publishing, then expose detector feedback and citation cleanup inside your editor.

02POST /api/v1/paraphrase

Writing tools

Add paraphrase, rewrite, and AI-writing review to existing document workflows without building the model layer yourself.

03POST /api/v1/detect

Review workspaces

Send submissions through detector endpoints, store review notes, and show reviewers the signals behind each estimate.

04POST /api/v1/citation

Research workflows

Format citation and bibliography output for source-heavy products, student tools, and academic writing assistants.

Production detail

Limits, billing, and reliability

These are the operational rules client apps should design around before enabling TurnitPass for real users.

Authentication

Bearer API key

Workspace API keys are shown once when created and can be revoked without changing Google login.

Transform limit

1,000 words/request

Humanize, paraphrase, and rewrite endpoints share the transform word limit and deduct successful requests from balance.

Detection limit

5,000 words/request

Detector requests support longer review inputs and return estimates, review notes, and signal details.

Rate limits

50 req/min/key

Transform, detector, and status endpoints default to 50 requests per minute per key; citation routes allow 100.

Billing path

Stripe-ready

Checkout, portal, webhooks, word balance, and plan limits are wired; live Stripe keys and price IDs stay configurable.

Failure handling

Charge on success

Transform words are consumed after a successful engine response, so failed validation or engine errors do not spend words.

Production notes

Privado por padrão. As solicitações ficam vinculadas à chave do usuário e podem ser acompanhadas com segurança para limites, suporte e controle de uso.

Faturamento e limites. O faturamento é gerenciado por um fluxo seguro com limites definidos por plano.

Before launch

Ship checklist

Create test key

Generate a workspace API key and confirm the prefix appears only once.

Run core calls

Call humanize, detect, paraphrase, citation, bibliography, and status with the same Bearer token.

Handle errors

Map invalid_api_key, rate_limited, insufficient_words, and validation errors in your client.

Set billing

Add live Stripe secrets and price IDs when your plan table and checkout copy are final.

Início rápido

Run the first request and confirm the response contract.

Referência de API
