FilingDelta sells JSON cards that summarise what changed in published documents: SEC filings (SEC EDGAR), central-bank decisions and US macro releases. The cards are derived from public filings and official publications, and each card is cited to its source (see source_url on the card).
Cards are summaries of what changed in published documents. They are not financial advice, not investment advice and not a trading signal. Check the cited source before relying on any card.
Cards and free samples are provided as is, without warranty of any kind, including accuracy, completeness or timeliness. Use them at your own risk.
Paid cards are charged per request through x402, in USDC on Base. Prices are shown on /catalog and /about, and in each card's HTTP 402 response. An unpaid request to a paid route returns HTTP 402 with the payment requirements instead of the card. Free samples and free pages need no payment.
Source attributions apply to every card and must be kept if you reuse card content.
