Your AI agents spend money. You should control how.
QuetraAI sits between your agent and every vendor, enforcing cryptographically signed spending mandates with sub-50ms policy evaluation.
$ quetra evaluate --amount 1200 --vendor stripe.com
evaluating mandate for agent "research-bot"...
checking 4 rules: category, vendor, rate_limit, max_amount

The Infrastructure Problem
Uncontrolled Agent Spending
Autonomous agents access paid APIs, purchase resources, and process payments without guardrails or approval workflows.
Budget Overruns
Without per-agent spending limits and rate controls, costs spiral — especially across multi-agent pipelines.
Governance Vacuum
No audit trail, no permissioning, no vendor controls. Enterprise-scale AI deployment becomes a legal and operational risk.
The QuetraAI Solution
A programmable governance layer that turns chaotic agent spending into controlled, auditable commerce.
Cryptographic Mandates
Ed25519-signed spending mandates define what each agent can spend, on which vendors, and when — tamper-proof and auditable.
Sub-50ms Enforcement
Real-time policy evaluation on Cloudflare Workers edge. Every transaction checked against budget, rate limits, and 7 rule types.
Complete Audit Trail
Append-only transaction log with approve/reject decisions, rule evaluation details, and budget snapshots for every spend event.
See It In Action
Monitor every agent transaction, manage mandates, and track budgets from a single dashboard.
How It Works
From zero to governed agent spending in under 5 minutes.
Register Agents & Set Mandates
Define spending rules, budget limits, allowed vendors, and rate controls for each AI agent through the dashboard or API.
Install SDK or MCP Server
Three lines of code. Works with any agent framework — LangChain, Claude, custom agents, or via MCP for zero-code integration.
Every Spend is Governed
Each transaction is evaluated against your mandate rules in real-time. Approved, rejected, or logged — all in under 50ms.
Multiple Integration Paths
Choose the approach that fits your stack — from zero-code MCP to full programmatic control.
SDK Integration
Drop-in TypeScript client that wraps fetch with automatic x402 payment negotiation, mandate evaluation, and budget tracking.
- Automatic x402 payment flow
- Budget-aware fetch()
- Works with any agent framework
import { QuetraClient } from "@quetra/sdk";
const client = new QuetraClient({
apiKey: process.env.QUETRA_API_KEY,
agentId: "research-bot",
});
// Every fetch is governed by your mandate
const data = await client.fetch("https://api.example.com/data");MCP Server
Zero-code governance for Claude, OpenClaw, and any MCP-compatible agent. Just add the server config.
REST API
59 endpoints for full programmatic control. Evaluate, manage mandates, track transactions from any language.
