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.
USDC-first · x402-ready · Built for Base and Solana
What to expect
Guardrails that act before money moves.
No seed phrase or root key exposed to an LLM
Every transaction evaluated before signing
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.
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.
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.
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.
Step 02
Policy before payment
Enforce transaction, daily, monthly, merchant, category, and velocity limits before anything is signed.
Step 03
Native x402 settlement
Let agents answer a 402 with policy-compliant USDC on Base or Solana, including sub-cent payments.
Pricing
Pay for the control layer as you grow.
Begin in a no-risk sandbox, move to production with transparent workspace and volume pricing, then add enterprise controls when required.
