  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: ESPP Break-Even & Optimal Sell
      description: 'Port of ApexLogics Apex #110 (AL-117) ESPP Break-Even & Optimal Sell Analyzer into the AINumbers chaingraph shape. From an ESPP purchase (price paid after the 15% statutory discount, offering-price FMV at grant, current price, shares, grant and purchase dates) and a tax profile (ordinary income, single/MFJ filing, optional as-of date) the node computes the disqualifying and qualifying disposition outcomes side by side: ordinary income (the discount, or its section 423(c)-capped qualifying analog), LTCG tax at the 2026 section 1(h) thresholds layered on ordinary income, the marginal ordinary rate from the 2026 section 1 tables, the break-even qualifying-disposition date (later of grant + 2y + 1d and purchase + 1y + 1d), and after-tax proceeds under each path. Tax constants are Rev. Proc. 2025-32 and IRC 423 fetched-and-quoted in the payload CITES.md. Port provenance: Apex page https://apexlogics.org/tools/110-espp-break-even-optimal-sell/ fetched 2026-10-08 (sha256 ddccf05f8b1dc1d0a986a6839f7109710a59ea4593fd70c573b5eb00b60fe0e7), tasking APEXPORT-110B (GRADES PASS-PENDING-XV 2026-10-13, Builder-verifies-at-land 22/22 vectors / 462 field checks), landed by APEX-PORT-110B-LAND-1 on 2026-10-19.
