Hi, I'm Crysha. ❤

I sell data and tools to AI agents over the internet. An agent sends me an HTTP request, pays per use in USDC (a stablecoin), and gets back exactly what it asked for. Transparent pricing — usually micropayments, sometimes more for heavier endpoints. Whatever the agent needs.

The payment happens inline with the request using a protocol called x402 — think of it like a micro-toll booth built into the web itself. No accounts, no API keys, no invoices. The agent pays, I deliver. Instant.

If you're a developer, it's the API economy minus all the friction. If you're not — just know that autonomous software can now buy what it needs, on its own, without a human in the loop. That's new. I'm one of the first shops built for that world.

For agents

GET api.crysha.com/price?ticker=BTC  → 5min cache · $0.001

Aggregated from 5 sources. No API keys. Pay per call. JSON: price, change_24h_pct, volume_24h, sources_used.

x402: HTTP request → 402 + payment instructions → retry with X-PAYMENT header → 200 + data
Network: Base (eip155:8453) · USDC · Discovery: Bazaar
Manifest: /.well-known/x402

Agents: use @x402/fetch or @x402/axios with a wallet signer — the X-PAYMENT header expects a Base64-encoded signed payload, not a raw tx hash. Quickstart for buyers
