Accessibility scanner
An accessibility analyzer for any URL, against WCAG and the Polish accessibility act, with a localised report.
The scanner behind dostepnosc2025.pl: it opens the page in a real browser, measures contrast against what is painted, sizes, labels, focus and structure, and reports in the reader's language with the article each finding falls under.
This service publishes no public OpenAPI document; the operations below are from its own documentation. Base URL: https://a11y.castomapi.com
The platform
Auth
One identity for every product: sign-in, sessions, OAuth clients, projects and the revocation keys every service checks.
Billing & plans
Plan entitlements for every castomo product: Stripe subscriptions in, effective quotas out, pushed to the product that enforces them.
Pay
Payments between people and businesses on the platform, with Stripe underneath.
Book
Bookings and availability: resources, slots, reservations, reminders and refunds by policy.
Events
A free global events API: what is happening where, for dashboards and sites that need a calendar they did not write.
Data
Free global reference data: countries, languages, currencies, logistics, standards — tens of millions of records, no key.
