Here is what developers building on Ohu have to say.
"Ohu's prompt injection scanner caught two hidden zero-font CSS attacks targeting our LLM crawler that three other security tools missed completely."
"The synthetic dataset generator saved us weeks of manual data engineering. We generated 5,000 instruction pairs from our documentation overnight."
"Ohu's RAG chunking with header path ancestry improved our vector search retrieval accuracy by over 34% compared to standard character splitters."
Everything you need to know about Ohu's API engine and platform.
Upon registration in the Developer Console, you receive a raw API key (`ohu_live_...`). Include this key in the `X-API-Key` HTTP header or `Authorization: Bearer` token on all API requests.
If your monthly request usage reaches your plan limit, subsequent API requests return `HTTP 402 Payment Required`. You can upgrade your plan anytime in the dashboard for immediate quota increases.
Ohu inspects the target web DOM for invisible text (`display:none`, `visibility:hidden`, `opacity:0`), offscreen coordinates (`left: -9999px`), zero-font sizing, hidden HTML comments, and leaked credential regex patterns.
Yes! The `POST /ohu/api/v1/pdf-to-markdown` endpoint accepts any accessible PDF URL, parses the document layout, and returns clean, structured Markdown text.
Yes. You can manage your subscription or downgrade back to the Free Developer plan anytime directly from the Developer Console using our Stripe billing portal integration.
