Built for classification at scale

Six primitives that make up every request. Understand them once, predict every response.

F.01

URL in, labels out

Send a URL, we scrape, extract the body, and classify. One hop, SSRF-safe, 5MB cap. Raw text is accepted too — skip the network when you already have the content.

Taxonomy-agnostic

IAB 2.2, sentiment, and toxicity ship today. One key, one response shape across every taxonomy. More models on the way.

Better economics

At 150k classifications a month we cost under a third of Klazify. At 500k we're a fifth. Rate cards stay on-page — no per-token math, no sales call to see a number.

$29 → 25k · $99 → 150k · $299 → 500k

Built for three jobs

Contextual ad targeting with IAB 2.2. Brand safety and moderation with toxicity. Content routing and CRM enrichment with sentiment. One API, the patterns your peers already expect.

Fine-tuned, not zero-shot

The iab-2.2 model is a fine-tuned DeBERTa-v3-large classifier, trained on web content we collected and labeled ourselves. Not a prompt wrapped around an LLM. Deterministic outputs, cheaper per request, and the taxonomy ships with the model.

Structured output

Ranked categories, confidence floats, taxonomy paths. Every response is the same shape across every model. No prompt engineering, no regex on prose.

{ id, name, path[], confidence } × N

One request from text to taxonomy

Language SDK or raw cURL — the contract is the same. Send text or a URL, receive ranked categories with confidence scores. No prompt engineering, no schemas to maintain.
