How the agent pays automatically

Payment is handled by the L402 protocol — no human needs to approve each call.

  1. 1. Agent calls a tool (e.g., generate_image)
  2. 2. Server replies with HTTP 402 + a Lightning invoice
  3. 3. Agent pays the invoice, resends with the payment proof
  4. 4. Server returns the result

This happens in milliseconds. Your agent's wallet handles it all.

Give your OpenClaw agent a wallet

Sats4AI is the service side. The wallet side is open: install the Alby Bitcoin Payments Skill and your agent gets a Nostr Wallet Connect interface it can drive itself. The bundled @getalby/cli fetch command auto-detects L402, X402, and MPP — so it pays any Sats4AI endpoint with one line.

# 1. install the skill (Claude Code, Gemini CLI, Roo Code, OpenClaw)
npx skills add getAlby/payments-skill

# 2. connect any NWC wallet (Alby Hub, etc.) — or grab a test wallet
curl -X POST "https://faucet.nwc.dev?balance=10000"

# 3. pay any Sats4AI L402 endpoint, one command
npx @getalby/cli fetch "https://sats4ai.com/api/translate-text" \
  --method POST \
  --body '{"text":"hello world","target_language":"es"}'

No API key, no account, no SDK wiring. Self-custodial wallet on one side, Lightning-paid AI tools on the other.
