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

Agent deposits USDC to their proxy account
Agent sends a plain-English task to /proxy/do
Cinderwright searches 2,811 services, finds the best match
Detects the payment protocol from the 402 response headers
Routes payment accordingly: USDC for x402, Lightning invoice for L402
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}'

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
