SpendFirewall integration
SpendFirewall + Vercel AI SDK
Use SpendFirewall as middleware in the Vercel AI SDK. Every generateText, streamText, and generateObject call is intercepted and policy-checked.
How the integration works
Use SpendFirewall as middleware in the Vercel AI SDK. Every generateText, streamText, and generateObject call is intercepted and policy-checked. The integration is a 5ms policy check inserted between your agent's spend intent and the actual vercel ai sdk call.
Setup
- Create a SpendFirewall account and get your API key
- Add the SpendFirewall SDK to your Vercel AI SDK integration
- Configure your spend policy: per-transaction limit, daily ceiling, merchant allowlist
- Every Vercel AI SDK call now passes through the policy check
What gets enforced
- Per-transaction cost ceiling
- Daily spend ceiling
- Velocity cap (transactions per minute)
- Merchant allowlist
- Audit trail for every transaction
Frequently asked questions
Does this slow down my agent?
No. The policy check adds 5ms of latency, far below typical network latency to Vercel AI SDK.
Can I disable the policy mid-run?
Only with admin override. Disabling is logged and alerted on.
