# FilingDelta

> What changed in SEC filings (10-Q and 10-K filing diffs), central-bank rate decisions and US macro data, in one call: cited JSON cards for agents. SEC filings for 19 tickers (10-Q, 10-K, 6-K, 8-K) and 9 central banks at $0.02 USDC, CPI, GDP and nonfarm payrolls cards at $0.01, paid per call on Base mainnet via x402 v2. Every card has a free sample: filing and macro samples are labelled trimmed views of the paid card, policy samples are the previous meeting's card, labelled.

## How to pay

- HTTP: GET https://filingdelta.xyz/delta/{ticker} (e.g. https://filingdelta.xyz/delta/AMD; tickers: AMD, MRVL, NVDA, AVGO, TSM, MU, AMAT, AAPL, MSFT, META, TSLA, ORCL, INTC, ASML, MSTR, JPM, BAC, GS, WFC) or https://filingdelta.xyz/policy/{id} (e.g. https://filingdelta.xyz/policy/BOE; ids: BOE, FED, ECB, BOJ, RBA, BOC, SNB, NOR, SWE) returns 402 with the x402 PaymentRequired (base64) in the PAYMENT-REQUIRED header: scheme exact, network eip155:8453, price $0.02, payTo 0x6d41a1B675cCF7980a0254d0C1317CccB4b42f2a. Sign it with an x402 v2 client and retry the same request with header PAYMENT-SIGNATURE: <base64 PaymentPayload>. The receipt comes back in the PAYMENT-RESPONSE header.
- MCP: POST https://filingdelta.xyz/mcp (JSON-RPC 2.0). Paid tools answer an unpaid tools/call with a normal result that has isError:true and the x402 PaymentRequired in structuredContent (JSON copy in content[0].text), the same object as the PAYMENT-REQUIRED header of the matching HTTP route. Retry the same tools/call with the PaymentPayload in params._meta["x402/payment"], or with header PAYMENT-SIGNATURE. The receipt comes back in result._meta["x402/payment-response"] and the PAYMENT-RESPONSE header.
- Macro: GET https://filingdelta.xyz/macro/{id} (e.g. https://filingdelta.xyz/macro/NFP; ids: NFP, GDP, CPI) returns 402 at $0.01 (scheme exact, network eip155:8453, payTo 0x6d41a1B675cCF7980a0254d0C1317CccB4b42f2a); same flow as above.
- CPI: GET https://filingdelta.xyz/cpi/US returns 402 at $0.01 (scheme exact, network eip155:8453, payTo 0x6d41a1B675cCF7980a0254d0C1317CccB4b42f2a); the same CPI card as https://filingdelta.xyz/macro/CPI; US only, other ids 404 free; same flow as above.
- Bundles (cheaper than buying the cards one by one; same card bodies as the individual routes, in one JSON): GET https://filingdelta.xyz/bundle/SEMIS = AMD, MRVL, NVDA, AVGO, TSM, MU, AMAT, INTC, ASML for $0.12; GET https://filingdelta.xyz/bundle/CENTRALBANKS = BOE, FED, ECB, BOJ, RBA, BOC, SNB for $0.08. Same 402 flow.
- Unknown tickers and ids return a free 404 before any payment; its JSON body lists the valid ids and an example URL.
