# AgentStack Research API

> Machine-payable market research for AI agents: taxonomy-classified company announcements and compound research bundles, returned as one identical JSON schema across every market. Pay per call in USDC on Base via the x402 protocol — no API keys, no signup.

AgentStack serves Australia (ASX): coming soon; United States (SEC/EDGAR): live. Request a priced route, receive an HTTP 402 challenge with payment instructions, pay, then retry to receive the data. Data and classifications only. Not investment advice.
