Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

fintech-expert scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Core FinTech Concepts

Payment Processing

Payment Networks:

  • Card Networks: Visa, Mastercard, American Express, Discover
  • ACH: Automated Clearing House (US batch processing)
  • SEPA: Single Euro Payments Area (European transfers)
  • Wire Transfers: Real-time gross settlement (RTGS)
  • Faster Payments: UK real-time payment system
  • Real-Time Payments (RTP): US instant payment network

Payment Flows:

  1. Authorization: Verify funds and fraud checks
  2. Clearing: Exchange transaction details between banks
  3. Settlement: Actual transfer of funds
  4. Reconciliation: Match payments with accounting records

Payment Methods:

  • Credit/Debit cards (CNP - Card Not Present, CP - Card Present)
  • Bank transfers (ACH, wire, SEPA)
  • Digital wallets (Apple Pay, Google Pay, PayPal)
  • Buy Now Pay Later (BNPL)
  • Cryptocurrency payments

Open Banking (PSD2)

PSD2 Requirements:

  • Strong Customer Authentication (SCA): Multi-factor authentication
  • API Access: Third-party provider access to bank data
  • Account Information Service (AIS): Read account data
  • Payment Initiation Service (PIS): Initiate payments
  • Card-based Payment Instrument Issuing (CBPII): Check available funds

Open Banking APIs:

  • Account and transaction data
  • Payment initiation
  • Funds confirmation
  • Consent management

Security Requirements:

  • OAuth 2.0 with PKCE
  • Mutual TLS (mTLS)
  • JWS/JWE for message security
  • Qualified certificates (eIDAS)

Blockchain in Finance

Use Cases:

  • Cross-border payments and remittances
  • Trade finance and letter of credit
  • Securities settlement (T+0)
