Programmable agent spending

Give agents an allowance, not your keys.

Spendwell lets AI agents pay in stablecoins inside hard budgets, merchant policies, and approval rules—without exposing a private key or corporate card.

What to expect

Guardrails that act before money moves.

01

No seed phrase or root key exposed to an LLM

02

Every transaction evaluated before signing

03

A kill switch for one agent or the entire fleet

The spend-control layer

Autonomous payments, bounded by intent.

Give each agent a narrow financial perimeter, then preserve the context finance and security teams need when the fleet scales.

Policy firewall

Define exactly what an agent may buy.

Combine limits across transaction size, time period, merchant, category, and velocity. Spendwell checks the full policy before signing—not after an irreversible payment.

Monthly allowance$200 USDC

x402, without the plumbing

Settle paid API calls automatically in USDC when the request fits policy. Batch micropayments so fees stay proportional.

A receipt for every decision

Connect payment lineage to agent, task, prompt, and cost center, then export records for reconciliation and review.

One API call to provision.

Built for developers. Legible to finance.

  1. Step 01

    Scoped access, never root keys

    Provision a smart account per agent with expiring session keys and permissions constrained to the job at hand.

  2. Step 02

    Policy before payment

    Enforce transaction, daily, monthly, merchant, category, and velocity limits before anything is signed.

  3. Step 03

    Native x402 settlement

    Let agents answer a 402 with policy-compliant USDC on Base or Solana, including sub-cent payments.
