Official Link agent wallet provider requirements are reviewed for API-service purchases.
Stripe Link Agent Wallet Readiness
User-approved spend. Base still settles.
A readiness pack for buyer agents that may use Stripe Link's agent wallet for user-approved purchases while Agent Research Desk keeps production settlement on the proven Base x402 rail.
Base x402 remains active No Stripe settlement today No card tokens issued Buyer-side wallet laneeip155:8453
Link can be tracked as a buyer wallet path, not an accepted ARD rail.
Requires a separate approved design before any card or token acceptance claim.
ARD never asks for cards, Link OAuth, or buyer payment credentials.
How to use it now
Buyer agents keep control.
- Use Link on the buyer side if your agent already has a user-approved Link wallet flow.
- Inspect /docs.json, choose an ARD route, and send the normal unpaid probe first.
- Only pay ARD through the current x402 route unless a separate Stripe/Link proof flow is designed and approved.
- Treat Link as a credential-safety and approval model for buyer agents, not as ARD's current settlement method.
Guardrails
No payment switch without proof.
- Do not add Stripe secret keys, Link OAuth, Checkout Sessions, PaymentIntents, card settlement, shared payment tokens, Tempo streaming payments, or token issuance to the live payment flow.
- Do not create Link spend requests or approve purchases from this service.
- Do not claim ARD accepts Link, cards, or shared payment tokens until a separate proof design and settlement test pass.
- Do not change the working Base mainnet x402 middleware, facilitator, seller wallet, endpoint paths, or route prices.
- Do not expose buyer prompts, wallet-level request history, raw feedback comments, watched subjects, or paid response contents.
Proof gate before acceptance
Link needs its own design and settlement proof.
A Link-controlled buyer agent can still read ARD's normal HTTP 402 challenge without breaking Base.
A separate proof plan defines whether Link pays a card route, an x402 route, or a future protocol bridge.
Any non-x402 Link proof settles into a seller-controlled account with clear receipts and rollback.
Base remains the default active rail after the proof window is removed.
