ICP Checker

Classify any website against your Ideal Customer Profile (ICP) using AI. Provide a URL and your custom classification prompt - the service scrapes the page content and returns a clear yes/no verdict with a confidence score, and on request the reasoning with a quote from the page.

[!NOTE] See the API Guide for the shared request lifecycle (sync, async polling, async webhook), error envelope, rate limits, custom_vars, and deduplication. This page documents only the fields and behaviour unique to this endpoint.

Two stages: decision only or with reason

Set with_reason per request:

`with_reason`	You get	Price
`false`	`icp` and `confidence`. `reason`, `evidence` and `evidence_verbatim` stay in the response with the value `null`, plus `reason_hint`.	1 credit less
`true`	The same decision plus `reason` and an `evidence` quote from the page, written for exactly that decision.	+1 credit

Without with_reason, your organization's setting applies: organizations that used the ICP Checker before 22 October 2026 keep getting the reason, new organizations start with the decision only. Existing integrations keep working unchanged.

The decision comes from a calibrated yes/no model; the reason is written afterwards for that same decision and never turns it. If the deciding model is unavailable, the previous model decides and explains in one go, so a request never fails for that reason.

Tips

Write detailed prompts with clear criteria for best results
The AI receives only the page's body text (no HTML, images, or scripts)
Works with any language - write your prompt in the language you expect the website to be in
For bulk classification, use the async API with callback_url
Use with_reason: false for pre-filtering large lists and with_reason: true where you show or check the reason
