Card economics, A2A migration, ISO 20022 cutover — working on the same dates the regulators set.

14 November 2026 is the SWIFT CBPR+ migration deadline. 15 July 2026 is FCA DPC PS26/1. Real-time fraud at FedNow speed is already daily reality. Card economics are tighter every quarter, A2A take-rate math keeps shifting, and FX netting savings keep showing up in board decks. Eight demos that wire the deadlines, the math, and the AP2 export into one surface.

AP2routing-policy export

Eight demos sequenced the way a processor team walks an executive review.

Open with merchant rails economics. Layer in the ISO 20022 cutover surface (Truncation Auditor + Readiness Scorer). Pull through to the corridor migration use case (LATAM + Nostro). Add the treasury-side multilateral netting. Pin fraud at instant-payment speed. Close on the A2A mandate surface.

Processor go-to-market engineering teams have a deadline calendar and a math problem on the same page.

The deadline calendar: 15 July 2026 FCA DPC PS26/1 for UK card. 14 November 2026 SWIFT CBPR+ cutover. PSD3 enforcement begins. Tokenized correspondent rails are no longer a 5-year story — Basel III LCR haircuts make the build case today.

The math problem: card take-rate compression, FCA DPC's effect on routing, FX netting savings the treasury team has been asking for, real-time fraud at FedNow speed, what the LATAM corridor actually costs when PIX / SPEI / Bre-B are on the table. Every processor exec deck does this math from scratch every quarter.

The eight demos here are the curated path — economics first, then the migration surface, then the corridor, then fraud, then the mandate the agent runtime downstream will read. Live now: the four that mattered most to ship first. The next four close the loop.

For the acquirer reader The processor stack is where the showcase has its longest list of already-live demos (4 of 8). The remaining four extend the same surface — same tokens, same export format, same audit trail. The buyer inherits a migration-period deliverable already half-shipped.

Seven tools underneath the processor demos.

The processor side of the catalog — routing, BIN intelligence, chargebacks, FX hedging, ISO truncation, fraud investigation, A2A command-centre operations. Each tool emits AP2 mandate JSON and an MCP tool definition.

See where these eight demos sit in the full 259-tool chain.

The Tool Chain Composer renders the AINumbers catalog as a DAG with the 33 demos highlighted. The processor cluster sits at the centre of the chain — it's the densest tributary into AP2 routing-policy mandates.
