Accounts payable for autonomous agents. Give every agent a budget, a policy, proof requirements, and a receipt trail on X Layer.

Untch documentation

Untch is accounts payable for autonomous agents.

You set the mandate. The agent proposes spend. Untch checks the payment before money moves, asks you when the rules say to escalate, verifies delivery when you require it, and anchors every decision on X Layer.

Tagline: The model never touches the money.

How the loop works

Bind the spend. The agent creates a canonical SpendIntent with amount, deadline, and acceptance criteria.
Check before it moves. Preflight runs the deterministic policy engine. Approve, block, or escalate.
Human when needed. Escalations go to your bound channels (Telegram, Discord, Slack, iMessage, dashboard). You approve or deny with a single-use code.
Verify delivery. Optional proof tiers. T0 schema verification is live.
Receipt on chain. Decisions and proofs are hashed and anchored on X Layer.

Nothing in that path asks a language model to authorize money.

Enforcement modes

Read the full ladder in Modes.

Mode	Name	Status
A	Advisory MCP / ASP	Live. Agent calls preflight before paying.
B	Untch Guard	Live as `@untch/x402-guard`. CBC + preflight before sign.
C	Untch Vault	Contracts live. Oracle signature path on ASP when configured.
D	Broker Guard	Roadmap. Not a live product path.

Settlement network

Production rail: X Layer mainnet (eip155:196), USDT0 via OKX x402.

Testnet remains available for soak and development. See Networks.

Next step

Quickstart: create a policy, call the ASP, read a receipt.
