Pay for API data automatically — multi-protocol (x402 + L402 + MPP), multi-chain, streaming sessions

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.

1. Discover APIs from the registry

npx @boltzpay/cli discover --protocol x402 --min-score 80 --category crypto-data

2. Get a price quote

text

npx @boltzpay/cli quote https://invy.bot/api

See the payment protocol, amount, and chain options without spending anything.

3. Fetch paid data

text

npx @boltzpay/cli fetch https://invy.bot/api

Automatically detects the payment protocol (x402, L402, or MPP), pays, and returns the API response.

4. Diagnose an endpoint

text

npx @boltzpay/cli diagnose https://invy.bot/api

Full diagnostic: DNS resolution, protocol detection, format version, pricing, health classification, and latency.

No Credentials?

Six of the seven commands work without any credentials:

• quote — get detailed pricing
• discover — browse the registry with filters (protocol, score, category, search)
• diagnose — full endpoint diagnostic (DNS, protocol, pricing, health, latency)
• budget — check spending limits
• history — view past transactions
• wallet — check wallet address and balance

Only fetch requires credentials (it makes actual payments).
