The neutral gate an autonomous agent passes before it issues a refund, credit, or charge.
No money-moving tool runs without a signed, content-free authorization. The model never holds the keys, your data never leaves your runtime, and every action settles to a receipt anyone can verify.
Verifiable by design
Now: workflow-level caps
A three-day workflow can burn through tokens before anyone notices the loop. AgentGuard gives the run one budget envelope, resumable checkpoints, and a receipt chain validated before continuing.
For developers
Use the same runtime locally: Node, Python, or the browser verifier. Build governed AI agents in 60 seconds. No terminal, no code for the owner flow.
Powered by OpenRouter. Works with OpenAI, Anthropic, Bedrock, and any OpenAI-compatible endpoint.
Outcomes, not tokens
AgentGuard maps law, accounting, insurance, real estate, and e-commerce outcomes to model and reasoning-effort routes built from the live OpenRouter catalog. Extraction, reconciliation, claim drafting, and reviewer checks do not need the same model or effort.
High-stakes steps can require a second pass: a configurable rule escalates to a higher-effort review before the action is allowed.
New models ship every week. AgentGuard re-prices against the live OpenRouter catalog daily, routes to the cheapest capable model and effort, and blocks China-origin weights for regulated verticals. You do not chase models. The router does, and the origin block holds.
The runtime layer your super-agent's forward-deployed engineer is missing. Agents make a billion requests in three seconds. AgentGuard is the verification chain, the spend cap, and the kill switch that lets a human stay in the loop without being in the loop.
“Agents make a billion requests in three seconds, so you need approval flows, inboxes that summarize what happened, logs, and easy rollback.” — Dan Shipper · Every podcast · May 2026
Every AI agent call your code makes runs through the same wrapper. Here's what it does before the provider sees the request.
Zero data plane.
"An AI consultant tells Axios one of their clients recently spent half a billion dollars in a single month after failing to put usage limits on Claude licenses for employees."
One command. Every AI agent action across your runtime, halted instantly. Signed receipt logged. Telegram notification posted. Provider never charged. The off-button the half-billion-dollar client should have had.
AgentGuard wraps your provider SDK. Every call is intercepted, projected cost is computed, and the call is blocked before dispatch if it would exceed your cap. The provider never sees the request. The provider never charges you.
Works with OpenAI, Anthropic, Bedrock, LangChain, CrewAI, Vercel AI SDK, Hermes, OpenClaw, and any framework where you bring your own provider client. Node: npm install @agentguard-run/spend · Python: pip install agentguard-spend
npm install @agentguard-run/spend · Python SDK: pip install agentguard-spend · Cross-language byte-identical canonical JSON + Ed25519 signatures.
Paste the prompt below into Claude, GPT, Cursor, Cline, Continue, Devin, or any AI coding assistant. The assistant reads agentguard.run/llms.txt and generates the integration code for your specific provider and framework.
Your team has one Anthropic or OpenAI account. Five engineers using it. One Claude Code session burned through the month's budget last week. AgentGuard adds per-user spend caps on the same API key, with signed receipts that show exactly who spent what.
Caps stack at any level. Most-specific wins when multiple apply. Every decision is Ed25519-signed and bound to the scope key, so the audit log shows the exact agent + user + team that triggered each block.
AgentGuard Spend is the live primitive in a broader AgentGuard agent-compliance roadmap, alongside Trace (cryptographic provenance), KYA (Know Your Agent), an LLM firewall, and the Kill Switch.
see the full architecture →Every agent action is Ed25519-signed at execution time. No database admin, infrastructure operator, or post-hoc modification can forge or alter a signed receipt. Orchestration platforms store mutable database rows; AgentGuard signs each decision so the audit trail survives any database write.
Works with LangChain, Claude Code, Cursor, Vercel AI SDK, Anthropic SDK, OpenAI SDK, Bedrock, Hermes, OpenClaw, or any custom stack. AgentGuard operates at the SDK layer, below orchestration. One install, no platform lock-in.
Per-agent financial limits enforced at the SDK level, not the application layer. Each cap check produces a signed, verifiable receipt. Verifiable by reviewers, investors, and compliance teams.
Multi-agent workflows produce a cryptographically linked attestation graph. Every hop is independently verifiable. No central authority required. Holds up to external audit without trusting the database.
Local-runtime spend caps and capability-gated model routing. Wraps OpenAI, Anthropic, and Bedrock SDKs. Hard caps per agent, user, team, and day. Ed25519-signed, hash-chained receipts. No data plane involvement.
npm install @agentguard-run/spend →Signed, tamper-evident audit trail for any agent stack. Ed25519 receipts chain across turns and agents via DAG attestation. Cannot be altered post-execution, even by the infrastructure operator.
Integration guide →Open-source chargeback receipt package compiler for Stripe / Visa CE 3.0 disputes. MIT-licensed npm package. Builds signed receipt packages locally, never submits, never proxies. Sibling to Spend in the AgentGuard family.
npm install @merchantguard/agentguard-cb →14 custom agent skills managing Dunecrest's production properties without human intervention. 5 scheduled jobs run continuously: infrastructure health monitoring, CVE scanning across active repos, patent-evidence harvesting, shadow QA verification, and cloud billing audit. The same agent architecture that ships in the AgentGuard SDK, running on our own stack.
Multi-agent workflows produce a cryptographically linked attestation graph.
Every hop is independently verifiable. No operator can forge a valid Ed25519 signature.
