Where do I get a seller ID?

From the seller object in a Kleinanzeigen listing response.

Does this include the seller's ads?

No. Run Kleinanzeigen seller listings for that.

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 seller, which is $5 per 1,000, and only sellers that resolve are charged.

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
Checking it by hand	Open the seller's profile and read it	Free, and slow	Fine for one seller, useless across a list
Building a scraper	Write it, host it, and repair it when the profile page changes	Engineering time	A maintenance commitment for something that isn't your product
NeuralVerge	One request per seller	$5 per 1,000, misses not billed	Returns what the profile publishes at request time; many fields are empty for new sellers
