SpendFirewall integration
SpendFirewall + Anthropic Claude API
Integrate SpendFirewall with the Anthropic Claude API. Every messages.create call passes through a policy check that enforces per-token cost ceilings, per-conversation velocity caps, and tool-use transaction limits before the request is sent.
How the integration works
Integrate SpendFirewall with the Anthropic Claude API. Every messages.create call passes through a policy check that enforces per-token cost ceilings, per-conversation velocity caps, and tool-use transaction limits before the request is sent. The integration is a 5ms policy check inserted between your agent's spend intent and the actual anthropic claude api call.
Setup
- Create a SpendFirewall account and get your API key
- Add the SpendFirewall SDK to your Anthropic Claude API integration
- Configure your spend policy: per-transaction limit, daily ceiling, merchant allowlist
- Every Anthropic Claude API 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 Anthropic Claude API.
Can I disable the policy mid-run?
Only with admin override. Disabling is logged and alerted on.
