Monthly Treasury Statement (MTS) — Table 4: receipts by source via US Treasury Fiscal Data. Returns monthly totals of federal government receipts grouped by classification (individual income tax, corporate income tax, social-insurance receipts, excise, customs, estate-and-gift, miscellaneous). Each row carries record_date, classification_id, classification_desc, current_month + current_fytd (fiscal year-to-date) gross_rcpt / refund / net_rcpt amounts, plus prior_fytd comparisons. Backbone of any "how much money is the federal government bringing in" question. Use Fiscal Data filter syntax.
/api/treasury/monthly-statementPAYMENT-SIGNATURE.The monthly statement API is a pay-per-call treasury endpoint built for AI agents and autonomous software. Monthly Treasury Statement (MTS) — Table 4: receipts by source via US Treasury Fiscal Data.
There is no signup and no API key. An agent (or any HTTP client) hits the endpoint, receives an x402 "402 Payment Required" challenge, signs a sub-cent USDC payment on Base or Solana, and retries — the data comes back on the paid request. That makes it a drop-in monthly statement data source for an agent tool-use loop, an MCP host, or a backend that needs treasury data on demand without onboarding to yet another vendor portal.
