  title: AINumbers.co Fintech Intelligence Suite A16z 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).'

      summary: Can't Be Evil NFT License Picker
      description: 'Deterministic rights-matrix lookup mapping creator answers (commercial, exclusivity, no-hate variant) to one of a16z''s six Can''t Be Evil NFT licenses (launch names CBE-CC0, ECR, NECR, NECR-HS, PR, PR-HS; current on-chain names PUBLIC through PERSONAL_NO_HATE, renamed in place October 2022, order unchanged). Returns license id, both on-chain enum names, Solidity LicenseVersion enum ordinal, full rights matrix verified against the canonical Arweave license texts, and canonical Arweave license URIs (current and legacy manifests, equivalent per index). Selection only, not legal advice. Zero PII.
