Verified responses

Real, verified responses from X1 mainnet — copy each request and run it yourself (no wallet, no key). The REST tabs are plain GETs on https://api.x1id.io; the SDK reads chain state directly. Writes (register, subnames, gifts) are signed transactions — see the API reference.

Read-only. No wallet and no API key. Signed writes need a wallet — see the API reference.

Reference

What X1ID is

A wallet address is 44 unreadable characters, and one wrong character sends funds nowhere. X1ID replaces it with a name you can read and share: register @you once and people pay it instead of copying an address, apps show you as @you instead of raw base58, and a single handle resolves to the right address on whichever chain the sender is on. It's permanent — no renewals, no expiry, on a standard registration (an optional lease-to-own path exists for spreading the cost) — and it carries a profile you own, so a wallet can finally prove who it belongs to. Start with Why get an X1ID, then claim your handle.

@you is a handle, not a domain. X1ID (@jack) and X1NS (jack.x1) are complementary — different shapes for different jobs, and many people own both. See how they fit together.

Get paid by name

Anyone scans and pays @you

Every handle gets a shareable payment code. Someone points a wallet at it and pays straight to @you — no copied address, no wrong-chain mistakes. The code carries your primary chain and resolves live.
