Crypto data API where AI agents pay per request with USDC (x402)
x402 micropayments are clever, but the API is a thin wrapper around existing crypto data sources.
Bloomberg Terminal of the AI Agent Economy — x402 micropayment routing, 31 AI providers, smart pricing oracle on Base

x402 micropayments are clever, but the API is a thin wrapper around existing crypto data sources.
Cloud pricing comparison covering 8 providers—but Finops tools and cloud vendors already do this.
They revive HTTP 402 so agents can automatically buy API calls — the repo ships PayingClient/WalletManager primitives, an @x402-kit/core package, five agent templates (web-scraper, image-gen, search, translation, code-review), a live demo and 93 tests. Smart infrastructure play with a clear demoable surface; the hard part will be UX and economics (wallet funding, gas/settlement, and convincing API operators to adopt x402 instead of existing billing).
One-liner x402 middleware for ElysiaJS; niche stack, nascent payment protocol adoption.
x402 micropayments kill API keys entirely, letting agents pay per parse with zero auth overhead.
x402 payments are real, but this SDK is betting on an infant ecosystem.
