  title: AINumbers.co Fintech Intelligence Suite Workbook API
  version: 1.0.0
  description: '**1255 fintech intelligence tools** covering ISO 20022, A2A payments, CFPB §1033, EU AI Act, DORA, MiCA, AML/KYC, BaaS, DLT/tokenization, ESG/climate finance, agentic payments (AP2, ACP, x402, Visa TAP, Mastercard Agent Pay), PQC migration, sanctions screening, and OpenChainGraph v0.4 computation chains.


    ## Transport


    > **The live transport is MCP JSON-RPC 2.0 at `https://mcp.ainumbers.co/mcp` — not REST.**

    >

    > This OpenAPI file is a **descriptive data-room artifact** — a machine-readable index of all tools and their input/output schemas. The REST paths (`POST /v1/tools/{name}`) described here are a projection; they become functional only if the optional REST shim (Area 2 Path B) is deployed.

    >

    > To call tools today, connect via the official MCP client SDKs. TypeScript: `@modelcontextprotocol/sdk`. Python: `mcp`.


    ## Architecture


    All tools run **entirely client-side** (browser JavaScript). Zero PII. Zero server calls after page load. Deterministic, reproducible outputs. Licensed CC BY 4.0.


    OpenChainGraph v0.4 compute-binding nodes additionally run **server-side on the MCP Worker** and emit verifiable artifacts with `execution_hash` (WebCrypto SHA-256 over RFC 8785 canonical JSON).'

      description: 'Loads a Spreadsheet Input Manifest for a run (WORKBOOK-1-BUILD-SPEC.md WB-2), surfaces the ranges to recompute in Excel, accepts a pasted range or CSV back per range, and produces a match/mismatch round-trip receipt (WORKBOOK-ROUNDTRIP-BUILD-SPEC.md XLR-1) naming every diverging cell. Reuses the WB-1 CSV parser and range digest; no second engine.
