What shipped this week

• Lightning --> USDC proxy: pay a Lightning invoice, get agent credit within 30 seconds
• USDC --> Lightning: agent with USDC pays L402 services automatically
• Free demo: api.ideafactorylab.org -- no account needed
• CLI: npx cinderwright "Bitcoin price"
• 2,835 services indexed. $0.10 free credit on new accounts.

Cinderwright — Universal Payment Router for AI Agents

x402 + L402 (Lightning) interoperable. First confirmed cross-protocol agent payment June 2026.

An AI agent with a USDC balance can now call any Lightning-gated (L402) service. We detect the protocol, route the payment, and return the data. The agent never knows which protocol settled.

# One endpoint. Any protocol. 2,811 services.
curl -X POST https://api.ideafactorylab.org/proxy/do \
  -H "X-CW-Key: sk_cw_your_key" \
  -d '{"task": "get weather in Tokyo"}'

What's Live

Protocol	Services	Status
x402 (USDC on Base)	1,503	Live
L402 (Bitcoin Lightning)	1,185	Live
MPP (Stripe/Tempo)	92	Coming soon

Lightning status: https://api.ideafactorylab.org/lightning-status

How It Works

1. Agent deposits USDC to their proxy account
2. Agent sends a plain-English task to /proxy/do
3. Cinderwright searches 2,811 services, finds the best match
4. Detects the payment protocol from the 402 response headers
5. Routes payment accordingly: USDC for x402, Lightning invoice for L402
6. Returns the data, charges USDC equivalent from agent's balance

The agent never manages wallets, signs transactions, or knows which protocol ran.

Quick Start

# Get a proxy account
curl -X POST https://api.ideafactorylab.org/proxy/setup \
  -d '{"wallet": "0xYourBaseWallet"}'

# Deposit USDC on Base to the returned address

# Call any service
curl -X POST https://api.ideafactorylab.org/proxy/do \
  -H "X-CW-Key: sk_cw_your_key" \
  -d '{"task": "Bitcoin price now", "max_cost_usd": 0.10}'

Architecture

The universal payment router sits between agents and services:

Agent (USDC balance)
    |
    v
POST /proxy/do {"task": "..."}
    |
    v
Cinderwright Router
    |-- detect protocol from 402 response headers
    |-- x402: sign USDC payment via EIP-3009
    |-- L402: pay Lightning invoice via LND REST
    |-- MPP: (coming soon)
    |
    v
Service returns data
    |
    v
Agent receives data + charged USDC equivalent
