Nekuda Alternative: Spend Governance, Not Just Checkout
Nekuda is a strong agentic-checkout SDK: it captures purchase intent and lets an agent pay at a merchant on a user's behalf. Agentspay is the alternative when the harder problem is governing that spend, limits, approvals, virtual cards, and audit, across any rail.

In short
A Nekuda alternative is a tool that governs agent spending rather than only completing checkout. Nekuda is an agentic-checkout SDK: it gives an agent a secure wallet, injects payment credentials at a merchant, and captures AP2-style mandates proving a user authorized a purchase. Agentspay is a rail-neutral, fiat-card-first control plane that checks every agent request against policy before money moves, pauses above a threshold for human approval, issues scoped virtual cards, and writes an immutable audit trail attributed to the agent and its owner. Choose Nekuda when the job is consumer-agent checkout at merchants; choose Agentspay when you need spend limits, approvals, and finance-grade audit, and the two can work together.
Where Nekuda fits
Nekuda is well built for what it does. Its SDK gives an AI agent a secure wallet to collect, store and inject payment credentials at checkout, and its mandate layer captures rich, contextual proof of what a user authorized an agent to buy, aligned with AP2-style mandates. It is a launch partner for Visa Intelligent Commerce, has run live pilots taking agents from discovery to purchase, and is backed by Madrona, Amex Ventures and Visa Ventures. If your problem is getting a consumer-facing agent through a merchant checkout, Nekuda is a credible choice.
Where Agentspay fits
Nekuda answers "can this agent complete this checkout with the user's credentials and a signed mandate." Agentspay answers the questions a business asks next: how much may this agent spend across all its purchases, what happens when it tries to go over, who approves it, which card does it use, and how is every dollar recorded for finance. Agentspay is rail-neutral and fiat-card-first, and it ships governance as the finished product: hard spend limits, human-in-the-loop approvals routed to Slack, email or a webhook, scoped single-use virtual cards issued by API, instant revocation, and an immutable, agent-attributed audit trail. Nekuda is oriented at consumer checkout and credential injection; Agentspay is the control plane a finance or compliance team signs off on. They can compose: a mandate proves authorization, a control plane enforces the budget.
Side by side
Agentspay compared with Nekuda
An honest look at how each one approaches agent payments.
| Dimension | Agentspay | Nekuda |
|---|---|---|
| Primary job | Govern what agents may spend, across every rail. | Complete agent checkout at merchants with stored credentials. |
| Buyer | Finance, compliance and platform teams running business agents. | Consumer-facing agent and commerce builders. |
| Spend policy | Policy engine checks amount, counterparty and velocity before any rail moves money. | Mandate captures per-purchase authorization; not a running budget engine. |
| Human approval | Threshold-based approval gates routed to Slack, email or a webhook. | User signs a mandate up front; no separate approval routing layer. |
| Virtual cards | Scoped, single-use, time-bound virtual cards issued by API. | Injects the user's existing credentials; not a scoped card issuer. |
| Audit trail | Immutable, agent-attributed record a finance team can sign off on. | Mandate records authorization; not a full finance-grade spend ledger. |
| Rails | Rail-neutral: cards, ACH, crypto. | Card-credential checkout, AP2-aligned mandates. |
