BoltzPay — Paid API Access for AI Agents

BoltzPay lets AI agents pay for API data automatically. It supports three payment protocols (x402, L402, and MPP) across multiple chains (Base, Solana, Tempo), paying with USDC, Bitcoin Lightning, or Stripe. Agents can discover 5,700+ scored endpoints from the live registry, evaluate pricing, open streaming sessions, and purchase API data in a single workflow.

No Credentials?

Six of the seven commands work without any credentials:

• - quote — get detailed pricing
• INLINECODE17 — browse the registry with filters (protocol, score, category, search)
• INLINECODE18 — full endpoint diagnostic (DNS, protocol, pricing, health, latency)
• INLINECODE19 — check spending limits
• INLINECODE20 — view past transactions
• INLINECODE21 — check wallet address and balance

Only fetch requires credentials (it makes actual payments).
