Privacy by design

Zero-knowledge proofs from government IDs. Verify personhood without revealing identity.

🧩

Multiple Providers

Supports Self and ZKPassport as verification providers

WinterTC compatibility

Built on standards, using only native Request and Response classes





Few lines to protect your appAny developer can add proof-of-personhood middleware to their server in a few lines of code.Currently supporting WinterTC compatible frameworks, such as Hono and Elysia.
typescript
import { x511, toHono } from 'x511-tba'

const { verified, verify } = x511({
  domain: 'https://mywebsite.com',
  basePath: '/x511',
  providers: ['self', 'zkpassport'],
  disclousures: {
    minAge: 18,
  },
})

const app = new Hono()

app.mount('/x511', verify)
app.get('/protected', toHono(verified), (c) => {
  return c.text("You're in")
})
typescript
import { x511, toElysia } from 'x511-tba'

const { verified, verify } = x511({
  domain: 'https://mywebsite.com',
  basePath: '/x511',
  providers: ['self', 'zkpassport'],
  disclousures: {
    minAge: 18,
  },
})

new Elysia({ adapter: node() })
  .use(html())
  .mount('/x511', verify)
  .use(toElysia(verified))
  .get('/protected', () => "You're in")
  .listen(8000, () => {
    console.log('Server is running on http://localhost:8000')
  })




One person. One proof.X511 uses HTTP 511 and zero-knowledge proofs to draw a line between humans and bots. You cannot fake a ZK proof. You cannot generate one without a real identity document. AI agents, bots, and scripts cannot pass through an X511 gate. Your identity stays yours.




Humans and agents. One protocol.
🤖Agent compatibleAI agents can act on your behalf. Sign under your agent and let it pass through X511 gates as you.
🧍Human verifiedEvery request traces back to a real person. One proof, one human. No fakes, no duplicates.
🔏You stay privateZero-knowledge all the way down. Prove personhood without revealing identity. Not to the server, not to anyone.
