## The read

Agents that can pay change commerce architecture. Protocol moves (x402, SPT, checkout rails) are infrastructure — the moat is trust, scoped authorization, and human-defined intent boundaries.

## What moved

- **Stripe expands Shared Payment Tokens to Mastercard Agent Pay, Visa Intelligent Commerce, Affirm, and Klarna** — [Stripe Blog](https://stripe.com/blog/supporting-additional-payment-methods-for-agentic-commerce)
  Stripe is rolling out broader Shared Payment Token (SPT) support for agentic commerce. When a customer authorizes an agent, Stripe provisions Mastercard Agent Pay or Visa Intelligent Commerce network tokens scoped to intent and shares them with the agent; the agent can reuse vaulted tokens across any seller accepting agentic payments. Sellers interact only with SPTs while Stripe provisions network and BNPL tokens behind the scenes. Affirm and Klarna BNPL flows surface confirmation in the agent UI and pass seller credentials to the BNPL provider. Etsy and URBN merchants already use SPTs in production. **Builder angle:** Agents can authorize scoped card and BNPL spend once via SPTs and settle across multiple merchants without exposing PANs or re-running checkout per seller.

- **Stripe adds SharedPaymentIssuedToken API for agent-issued scoped payment grants** — [Stripe Documentation](https://docs.stripe.com/changelog/dahlia/2026-04-22/shared-payment-issued-token.md)
  API version 2026-04-22.preview adds SharedPaymentIssuedToken: agents create scoped grants via POST /v1/shared_payment/issued_tokens (payment_method, seller_details.network_business_profile, usage_limits for currency, max_amount, expires_at), retrieve status with GET, and revoke with POST .../revoke. Tokens include network_business_profile for seller context and validate against Orchestrated Commerce Agreements for delegated payment relationships. **Builder angle:** Agent platforms get explicit create/retrieve/revoke endpoints to issue time- and amount-bounded payment grants tied to a seller profile before handing tokens to merchants.

- **Cloudflare Agents SDK documents x402 and MPP payment flows with MCP server hooks** — [Cloudflare Developers](https://developers.cloudflare.com/agents/agentic-payments/)
  Cloudflare's Agents SDK supports HTTP 402 agentic payments via x402 (Coinbase stablecoin rail with PAYMENT-REQUIRED, PAYMENT-SIGNATURE, PAYMENT-RESPONSE headers and facilitator settlement) and Machine Payments Protocol (MPP, co-authored by Tempo and Stripe, using WWW-Authenticate: Payment / Authorization: Payment on the IETF track). Server-side MCP integration includes withX402 and paidTool; client-side withX402Client auto-handles 402 retries. MPP accepts cards via Stripe SPTs, stablecoins, and Lightning; MPP clients are backwards-compatible with existing x402 services. **Builder angle:** MCP tool servers can gate paid tools behind 402 challenges and let agents settle via x402 stablecoins or MPP card/SPT rails without accounts or API keys.
