Prices excl. VAT. Monthly billing, no long-term commitment — change or cancel anytime. Indexing your catalog is never counted against your request quota. Ranking has its own quota, separate from search — check the option on Growth or Scale for -25%, or subscribe to it standalone, without search. By subscribing, you accept our Terms of Service.

Browse traffic is separate from search traffic — counted and billed separately, with -25% if you already have a Search plan above. Counting details in the documentation.

How it works

How is a request counted?

Simple by design: a request maps to a concrete engine action.

SearchEvery search typed by a visitor counts as one request (the engine responds from the 3rd letter by default, like most modern engines)
IndexingNever counted. Update your catalog as often as you need; only the total number of indexed products is capped by your plan
API callsManagement calls are not counted: keys, accounts, subscription, merchandising priorities, analytics. A few endpoints are the exception and count as one request — each is listed in the documentation
RankingEvery call to a category page counts as one Browse request — on a separate counter from search, only if you're subscribed to Browse
OverageBeyond the volume included in your plan, the surplus is billed at the rate shown on your plan — never an abrupt service cutoff
Integrations & Documentation

Connect to your stack, without friction.

The REST API is fully documented — authentication, search, indexing, Ranking, facets, analytics. The JavaScript library and MCP server are published. E-commerce platforms connect through this API, using the guides on the Integrations page.

Frequently asked questions

What we get asked most about the Search API.

How do I get started?

Start the 14-day free trial (no credit card required), index a first batch of products, run a search. The quickstart guide fits in 3 API calls.

Can I change plans or cancel anytime?

Yes. Monthly billing, no long-term commitment. You change plans or cancel whenever you want, no penalty.

Does the Heurix engine replace Algolia or Elasticsearch?

It's not a layer on top of existing solutions: it's a different engine, specialized for catalogs where references matter — dimensions, sizes, standards, vintages. The Search API makes sense as soon as you don't yet have a dedicated engine, or yours fails on this type of search.

What happens if I exceed my request quota?

The service keeps working normally — the surplus is simply billed at the per-tier rate shown on your plan. You're warned before any significant overage, no surprise cutoff.

Can I create rules for my own industry?

Eleven packs are provided (hardware, automotive, electrical, plumbing, industry, electronics, fashion, wine, books, finance, sport) and cover most technical catalogs. A term specific to your catalog isn't in there? Add your own Custom Rules directly from the console, no regex required — included in all plans, effective immediately. For a more complex need (patterns combining two numbers, for example), a fully custom pack is available on Scale plans.

Is Ranking included in my Search plan?

No, it's a separate product with its own quota — you can take it standalone (without a Search plan) or as an option on Growth/Scale, with a 25% discount in that second case. The two quotas never step on each other: your search volume is never affected by your category-browsing traffic, and vice versa.

Not sure where to start?

The getting started guide covers the whole journey — sign-up, first catalog, then the optional modules one by one.
