How do I read one notice in detail?

Use Mexico company with the publication number, or open document_url.

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?

1 point per returned record, which is $1 per 1,000, and only records that come back are charged. Points come out of your monthly plan allowance, so there is no separate per-country contract.

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 the company on PSM (Registro Público de Comercio publications) and page through the list	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	$1 per 1,000, misses not billed	Covers Mexico — other countries are separate sources with the same request format

Integration

How to run it

The same lookup works from the app, the API, or as a tool an agent can call mid-task.

Results come back in the same envelope as every other source: a session id, a readable summary, the structured result and the points charged.

curl -X POST https://api.neuralverge.ai/functions/v1/run-mx-company-publications \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"company":"Cemex, S.A.B. de C.V.","max_items":2}'

Coverage & limits

Coverage, freshness and limits

What this source covers, how fresh it is, and where it stops.

Coverage

Mexico — entities on PSM (Registro Público de Comercio publications).

Freshness

Read at request time, so the answer reflects the register as it stands when you ask.

Handling

PSM (Registro Público de Comercio publications) is a public register. Every response carries the source URL it was read from and a session id you can trace.

What it will not do

—Covers what the company published in PSM, not every filing in the Registro Público de Comercio.
—The response lists notices and links; the text of each notice is at document_url.
—Matching is by company name, so confirm the company field on each record.
