Getting started

Introduction

What the Nostimates API returns, who it is for, and the two decisions that shape every endpoint.

Nostimates comes as a dashboard your team logs into and as a read-only measurement API — this reference covers the API. You send prompts, we collect each AI answer surface the way that reproduces what a user sees — a provider API where it matches, a rendered browser session (often through a residential proxy) where it doesn't — and we return who was cited, who was mentioned, and how confident you can be in that number.

Two decisions that shape everything

First, we never serve a number that doesn't match what a user sees. Provider APIs like OpenAI's web search tool, Perplexity's Sonar and Gemini's grounding metadata can come from a different model tier with different retrieval and ranking, with no shopping cards, no ads and no fan-out. Where an API returns what the interface returns, we use it; where it diverges, we render the interface — because an API-sourced answer that matches nobody's experience is worse than no number.

Second, we sample every prompt n times and return a distribution. A single reading of a non-deterministic system is not a measurement. Every metric you get back carries a 95% confidence interval so your client reporting survives the follow-up question.

Who this is for

Brand, marketing and in-house SEO teams who want the data in their own warehouse or product (the dashboard is the no-code way to get the same numbers)
SEO and AEO agencies building their own client dashboards on top of our data
Platforms embedding AI visibility as a feature

White-label by default

Nothing in the API response names us and no attribution is required. Agencies, in-house teams and brands all build their own reporting on top of the same data.
