What is a publication number?

The identifier PSM gives each published notice, in the form year-number as in 2026-0000001606.

Do I pay for lookups that come back empty?

No. You are charged per result, so a request that finds nothing costs nothing. Testing this against a messy list is free to get wrong.

What does a lookup cost?

5 points per resolved lookup, which is $5 per 1,000, and only successful lookups are charged. Points come out of your monthly plan allowance, so there is no separate per-country contract.

Mexico Company Notice API and MCP — Registro Público de Comercio Publication Lookup

This source reads the company publications of the Registro Público de Comercio (PSM), not a classic company record. Send a publication number and you get that one notice: the company name, its legal form, the type, title and date of the publication, a link to the published text and a publication history.

Run it in the app Read the API docs

You send: a publication number
You get back: One company notice with legal form, publication type, title, date, link and publication history
Coverage: Mexico — entities on PSM (Registro Público de Comercio publications).
Price: 5 pts — $5 per 1,000; Charged only when the record resolves. A lookup that finds nothing is not billed.

Comparison

Ways to get this data

Three approaches teams use today, and where each one runs into trouble.

Approach	What it takes	Cost	Trade-off
PSM (Registro Público de Comercio publications) directly	Open PSM (Registro Público de Comercio publications) and read the record	Usually free, sometimes per-document	A different interface, language and data shape for every country you add
Collecting it yourself	Build and host a crawler per register, then keep each one alive	Infrastructure and maintenance	Registers change their pages without warning, and nobody is on the hook when yours breaks
NeuralVerge	One request, the same shape as every other source in the catalog	$5 per 1,000, misses not billed	Covers Mexico — other countries are separate sources with the same request format
