Claim your listing

Is one of these your product? Email us what we got wrong and we will fix it. This is free and always will be — corrections from the people who built the thing make the catalogue better, and we would rather have them than be right in public.

Write from an address at the product’s own domain, or from the account the product publishes as. A claim we cannot tie to the product is read as a correction from a stranger, which we still welcome but do not record as yours. We never publish the address.

What to put in it

  1. The cardIts URL. A venue and its API are separate cards, so paste the link rather than naming the company.
  2. What we got wrongThe field and the right value. Quoting the line from the card is the fastest version of this.
  3. Where we can check itA fee schedule, a rulebook, a changelog, a docs page.
  4. Your own description (optional)Published verbatim in a block of its own headed From the vendor, and never used to rewrite ours. Plain text, 600 characters at most.

Free, forever. It fixes facts and moves nothing else.

What happens after you write

First an initial review: the address you wrote from has to tie to the product, and the correction has to match the page you sent us to. Then we change the field, move the card’s date, and record the card as confirmed by its vendor, with the date of that confirmation. Once the change is live we reply, usually within a week. If what you dispute is our wording rather than a fact, we will hear it out once, and after that the card stays as written.

What claiming does not change

Claiming does not move the card up a listing, does not add a rating, does not remove a limitation we described, and does not put your wording into our description: vendor copy is published in its own labelled block, and the two are never merged. There is no version of this that costs money. What is for sale is on the advertising page.
