Directory Submission Lite API

Orders submission of a website to twenty directories and returns a confirmation number.

Places an order to have a website submitted to twenty directories that publish a link back to it, and returns a confirmation number so the order can be checked later for free.

Pricing

$10.00 per request — pay via x402/USDC. No account needed.

How to use

Call this once per website to order directory submissions. Save the submissionid from the reply — it cannot be recovered and it is the only way to retrieve the order. Do not call this again to check progress; that would place a second paid order. To check progress, send the confirmation number to the /status address on this same service, which is free.
