LiveAuth - Proof-of-Work Authentication

Core Auth

Proof-of-work verification that humans pass instantly, bots can't afford.

verified_user

How It Works

LiveAuth generates a cryptographic challenge that browsers solve in 200-800ms. Real devices pass instantly; bots pay the CPU cost.

No cookies or fingerprinting
21 sat Lightning fallback option
JWT tokens returned on success

npm install @liveauth-labs/sdk

import { LiveAuth } from '@liveauth-labs/sdk';

const liveauth = new LiveAuth({
  publicKey: 'la_pk_xxx',  // Public key from dashboard
  apiKey: 'la_sk_xxx'      // Secret key from dashboard
});

const result = await liveauth.verify();
// result: { method: 'pow' | 'lightning', token: 'jwt...' }

Agent Auth API

Low-level API for building custom agent authentication. Perfect for OpenClaw and autonomous agents.

PoW-based verification
Token-based session management
Works with any AI framework

# Start auth - get PoW challenge
curl -X POST https://api.liveauth.app/api/agent/auth/start \
  -H "Content-Type: application/json" \
  -H "X-LW-Public: your-public-key" \
  -d '{"agentId":"my-agent","publicKey":"your-secret-key"}'

# Verify solution - get auth token
curl -X POST https://api.liveauth.app/api/agent/auth/verify \
  -H "Content-Type: application/json" \
  -H "X-LW-Public: your-public-key" \
  -d '{"sessionId":"uuid","solution":"challenge:nonce"}'

# Validate token
curl -X POST https://api.liveauth.app/api/agent/auth/validate \
  -H "Content-Type: application/json" \
  -H "X-LW-Public: your-public-key" \
  -d '{"token":"jwt-token-here"}'

L402 + x402 Payments

Monetize your API with per-request Lightning payments.

Pay-Per-Use API Access

Gate endpoints with Lightning payments. Agents pay as they go. No subscriptions required.

1-10 sats per API call
Automatic payment flow (402 → invoice → token)
Token valid for 1 hour
Compatible with x402 (Cloudflare/Coinbase standard)

# 1. Get invoice
curl -X POST https://api.liveauth.app/api/public/l402/invoice
# → { "bolt11": "lnbc1...", "paymentHash": "..." }

# 2. Client pays invoice, then validates
curl -X POST "https://api.liveauth.app/api/public/l402/validate?paymentHash=..."
# → { "token": "l402_xxx" }

# 3. Access gated endpoint (L402 format)
curl -H "Authorization: L402 l402_xxx" https://api.liveauth.app/api/mcp/start

# OR use x402 format (Cloudflare/Coinbase compatible)
curl -H "Authorization: x402 preimage_xxx" https://api.liveauth.app/api/mcp/start
