DeniableDeniable API
Put pre-generated test documents into your workflow.
The Deniable API returns synthetic documents and their metadata as JSON. Use it for parser tests, RAG evaluation, model training, QA workflows, and repeatable application checks without building a generation pipeline yourself.
How access works
Predictable retrieval, prepaid usage.
Create an account
API access is authenticated. Your key belongs to your account and can be revoked or replaced.
Add prepaid credits
Buy any amount from €5 upward. There is no monthly subscription and no automatic renewal.
Retrieve what you need
Request a category, format, language, and document count. The response includes the document content and catalogue metadata.
Keep your test pool varied
Deniable tracks delivered document IDs per key and favours documents you have not received yet before starting another cycle.
Usage rules
One clear unit for every response.
A standard support thread, review, social thread, meeting transcript, legal or HR document, code Q&A, or mixed edge-case item costs 1 credit. Long-form documents and ebooks cost 10 credits. If your balance reaches zero, the API stops serving requests until you add more credits.
Rate limits protect every API key, and your account dashboard keeps the complete credit and delivery history visible. Auto-renewal is intentionally unavailable: you will never receive recurring charges, and a leaked key cannot create an automatic subscription bill.
