Boltwork
Pay-per-call AI API for autonomous agents. No accounts, no subscriptions. Pay via Lightning and get results instantly.
Overview
Boltwork is a revolutionary pay-per-call AI API designed for autonomous agents. Instead of managing API keys, subscriptions, or accounts, you simply call an endpoint, automatically pay a Lightning invoice, and receive the result — all in one seamless transaction. Built on Bitcoin's Lightning Network, Boltwork enables instant micropayments for AI services, making it ideal for agent-based systems that need to access AI capabilities programmatically without overhead.

- PDF Summarisation: 500 sats (~£0.04) per call
- Code Review with Security Analysis: 2000 sats (~£0.17)
- Web Page Summarisation: 100 sats (~£0.008)
- Translation in 24 languages: 150 sats
