API tokens
Our ads.txt validator, sellers.json checker and comparison tool are available over a REST API, paid for with tokens you buy in advance. No monthly commitment, and nothing expires for 12 months.
Tokens buy those three tools, on any plan, the free one included. The endpoints that manage your own domains and groups need a plan that includes API access, which is the Ad Network plan above; it includes the whole API with no tokens at all.
Verify your email address and we credit 1,000 tokens, free, so you can build against the API before deciding anything. Read the API documentation.

A validation, of an ads.txt or a sellers.json, costs 1 token, or 2 if we fetch the file for you. A comparison costs 1 token for each domain you ask about. Sold to businesses only, so we ask for your company name, registration number and country before the first purchase. See the API Token Terms.
Frequently Asked Questions
What is the difference between Publisher and Ad Network?
Ad Network includes everything in Publisher. The line between them is whose websites your collaboration groups can hold: on Publisher a group keeps records in step across your own websites, up to 100 of them, and on Ad Network it can also hold other publishers' websites, so the records you keep there appear in their ads.txt files, up to 1,000 websites in all. Ad Network adds collaborator certification, which lets publishers find your groups, the whole API with no tokens to buy, and priority support.
Do my publishers need an account?
Yes, a free Basic account with their website added is enough. You invite a website by its tag, or share your group's tag so they can ask to join, and they stay in control of their own ads.txt file. Our comparison tool checks any website, account or not.
Do I need a credit card to sign-up?
No, you do not need a credit card to sign-up, your payment details will be requested towards the end of your free trial when your first renewal payment is due.
Can I cancel my membership?
Yes, you can cancel or change your membership plan at any time without penalty. You are under no obligation to maintain your membership.
What payment methods do you accept?
We accept all major credit/debit cards, including Visa, Mastercard and American Express. PayPal payment is not currently available.
Can I collaborate on more than 1,000 websites?
Yes. The Ad Network plan covers up to 1,000 websites across all your collaboration groups, your own and your publishers' together, and larger allowances are available. Please contact us if you need more.
Do I need a plan to use the API?
Not for the ads.txt validator, the sellers.json checker or the comparison tool. Those three are paid for with tokens, on any account, with no subscription at all. The rest of the API manages the domains and groups inside your own account, and that needs a plan which includes API access, which is the Ad Network plan above. Verify your email address and we credit 1,000 tokens free, so you can build against it before deciding anything.
Do API tokens expire?
Your balance expires 12 months after your most recent purchase or credit, and buying more tokens extends the expiry of your whole balance rather than only the tokens you just bought. Token purchases are non-refundable, and they are sold to businesses only, so please read the API Token Terms before you buy.
