The problem

Multi-LLM monitoring means five integrations. Or one.

Every model vendor has its own API, auth, rate limits, and response quirks. That’s a lot of glue code for one feature.

Five SDKs, five schemas

OpenAI, Google, Anthropic, Perplexity — each integration brings its own auth, billing, retries, and a response shape you have to normalize.

→ One REST API, one JSON schema, one invoice.

Model APIs ≠ what users see

Raw completions miss what real ChatGPT search shows people: web sources, citations, and answer formatting.

→ Scraper endpoints capture the real user-facing answers.

Historical prompt data doesn’t exist upstream

No model vendor will tell you what people asked last month — or which brands got recommended.

→ 280M+ collected prompts, searchable by brand, keyword, or domain.

What is an LLM monitoring API?

An API that lets you observe what large language models answer — at scale. With DataForSEO that means three things: querying models directly (LLM Responses), capturing real user-facing results (LLM Scraper), and searching a 280M+ prompt database for brand and domain mentions (LLM Mentions).

Which LLMs are supported?

The LLM Responses API covers ChatGPT, Gemini, Claude, and Perplexity with the same request format. The LLM Scraper covers ChatGPT and Gemini. The mentions database spans ChatGPT and Google AI Overview.

Do I need my own OpenAI or Anthropic accounts?

No. One DataForSEO account covers every supported model — no separate vendor keys, billing relationships, or SDKs to maintain.

What does a response include?

Structured sections with text and inline citation annotations, the exact model version used, token counts, per-call cost, and related fan-out queries — the same JSON shape for every model.

How much does it cost?

Pay-as-you-go: LLM Responses from $0.0006 per task plus the LLM’s own charges, LLM Mentions at $0.1 per request plus $0.001 per row, LLM Scraper from $0.0012 per results page. $1 free trial credit, $50 minimum top-up, credits never expire.

Can I test it before integrating?

Yes — register for $1 in free credits, use the free Sandbox for development, and fire test calls from the browser-based API Explorer before writing a line of code.

Can I white-label this data in my product?

Yes. It’s raw JSON you can reshape into your own features, dashboards, and client reports.
