JSON Schema API
Validate JSON against JSON Schema, server-side. Check any data against a schema (Draft-07 or 2020-12) and get a clear pass/fail plus a detailed list of every error with its instance path, failing keyword and message; verify that a schema itself is well-formed; or infer a starter JSON Schema automatically from a sample document, complete with detected formats like email, URI and date. Built on the battle-tested Ajv engine with full format validation. Every endpoint accepts GET (JSON-encoded parameters) or a JSON POST body and runs entirely locally with no third-party upstream, so responses are instant and the service is always available. Ideal for API request/response validation, form and data-entry checks, ETL and data-quality pipelines, no-code platforms and contract testing.

Credit Card API
A fast, fully-local payment-card toolkit: validate card numbers with the Luhn (mod-10) checksum, detect the brand by IIN/prefix (Visa, Mastercard including the 2-series, American Express, Discover, Diners, JCB, UnionPay, Maestro), format and mask numbers with brand-correct grouping, list supported brands with their valid lengths and CVV length, and generate synthetic Luhn-valid TEST card numbers for QA. Pure server-side compute, no third-party upstream, and inputs are never logged. It is algorithmic only (no real issuer/bank BIN-database lookup). Ideal for checkout forms, payment flows, fraud pre-checks and test fixtures.

IBAN Validation API
Validate IBANs with the ISO 7064 mod-97 checksum and per-country length and structure checks, and resolve the BIC and bank details for supported countries. A local parse endpoint works for every IBAN country offline; the validate endpoint adds bank-code verification and BIC. Ideal for payments, billing, onboarding and KYC.
