How this service works
Pay-per-call market and economic data API for AI agents: US stocks, ETFs and options, forex, crypto and on-chain perps, energy commodities, US and global macro (Fed, CPI, jobs, GDP, Treasury, World Bank), SEC filings, congressional trades, and market sentiment. No API keys, no accounts. Pay per request in USDC via x402 on Base.
Output
A JSON object listing all x402-compatible services crawled from public discovery catalogs, with per-host resource and pricing details, overall price distribution (min, max, p25, median, p75), total resource count, breakdown by blockchain network and data category (financial-data, search, enrichment, media), and the timestamp of the index.
Example use cases
Example prompt
“Give me a live snapshot of all the pay-per-call financial data services indexed by x402stock — I want to see how many paid resources are available, their price range, and how they break down by category and network.”
Technical details
Endpoint
GEThttps://x402stock.xyz/api/v1/x402/economyWhen to prefer
Use this endpoint when an AI agent needs to discover what x402-protocol financial and economic data APIs exist, compare pricing across services, or build a meta-view of the pay-per-call data ecosystem before deciding which specific endpoint to call. Prefer this over individual endpoints when the goal is service discovery rather than fetching specific market data.
Side effects
- Invalid or unrecognized 'properties' filter returns empty or default index
- Service temporarily unavailable returns HTTP 5xx
- Payment not completed or malformed x402 header returns 402 Payment Required
- Stale index if upstream discovery catalogs are slow to update
