Artha - Pay-per-call financial data API with x402 on Base
by•
Artha gives developers instant access to financial data — stocks, crypto prices, fundamentals, and SEC filings — through a single REST API.
What makes it different: no monthly subscription. You pay per API call in USDC on Base, using the x402 protocol. Connect your wallet once, and x402-fetch handles payments automatically in the background.
Built for developers who want to ship fast without committing to a data plan.

Hey PH! 👋 I'm the maker of Artha.
The idea started simple: I needed financial data for a side project and was frustrated by $500/month subscriptions I'd barely use.
So I built pay-per-call instead. You hit the endpoint, x402-fetch handles the USDC payment on Base automatically, you get the data. No plans, no contracts.
Currently supporting: US stocks, crypto prices, fundamentals, and SEC filings.
Happy to answer any questions about x402 micropayments or the tech stack!
