Generate realistic mock data from a JSON Schema. Send any JSON Schema and get back data that conforms to it — honouring types, formats (email, uuid, date-time, uri, ipv4 and more), minimum/maximum, string length and patterns, enums, required fields, and nested objects and arrays. Ask for a single object or an array of up to 100. Add a "faker" keyword on a property (e.g. "faker":"person.fullName" or "commerce.product") to get specific realistic values powered by Faker. Unlike fixed-entity fake-data generators, the shape is entirely driven by your schema — perfect for API mocking, test fixtures, database seeding, prototyping and contract testing. Pure local generation — no key, no third-party service, instant. Live. 2 endpoints. Distinct from JSON Schema validation and from canned mock-data entities.

Disposable / temporary email as an API — no key, no signup. Spin up a throwaway mailbox in one call (you get back the address plus a token), then receive real inbound email and read it: list the inbox, open any message with its full HTML and plain-text body and attachments, mark messages seen, delete a single message, or delete the whole mailbox when done. List the available mailbox domains and look up account details (quota, usage). Perfect for sign-up flows, OTP / verification-code capture, QA and end-to-end test automation, and throwaway registrations. Inbox endpoints use a per-mailbox token returned by /v1/account/new (pass it as ?token= or an Authorization: Bearer header). Every call is live (no cache). 9 endpoints, backed by the public mail.tm service. Mailboxes are ephemeral. No upstream key, no cache.

Generate realistic fake data — users, postal addresses, companies and products — for testing, prototyping, demos and database seeding. Localizable to many languages and regions for names, addresses and phone numbers. Server-side and deterministic to call, ideal for CI fixtures and frontend mock states.
