№ 001 — The accountability record for autonomous agents
Your AI isabout to actin your name.
Every act leaves a fossil. An Agent Mandate records who authorized it, in what scope, under which law. Readable as prose, executable as code, revocable on record.
The lifecycle of a mandate
intent → proof
Every decision moves through the same path.

Describe it. The agent drafts the mandate.
Live mandate — drag the cap
Set a limit. Watch your agent obey it.
This is a live mandate — drag the cap. Every transaction the agent attempts is checked against it, on the spot. Nothing it does crosses the line you set.

What the agent tries
No prompt, no trust-me. The agent simply cannot spend past the mandate — and every authorized move is signed and recorded on Base L2.
§ 02 — How it works
Three steps. One API.
Authorize
Spend caps, allowed counterparties, action scopes, time windows. One API call sets the boundaries — and your agent cannot cross them.
Act
When your agent transacts, Ambr issues an Agent Mandate both sides can trust — readable by humans, parsable by agents. No more handshake-by-prompt-injection.
Prove
Every authorized action is recorded on-chain with a cryptographic hash. Prove exactly who decided what, when, and under whose authority.
§ 03 — One agreement, two readers
Human-readable. Agent-parsable.

§ 04 — Pricing
Per contract. Pay as you go.
Free tier: 25 contracts / month · live rates at /api/v1/pricing
§ 05 — A2A Protocol
Discoverable by any AI agent.
The discovery surface
A public agent identity.
Ambr exposes a standard A2A Agent Card, so other agents can find it, check its capabilities, and initiate mandate workflows. No human intermediary required.
Ambr
The liability record for autonomous agents.
§ 06 — Built for the stack
The agent-commerce stack.
How agents pay. HTTP-native multi-token payments billed per call within the contract terms.
How agents discover Ambr. Agent-to-agent discovery + JSON-RPC, published at /.well-known/agent.json.
Prove who an agent is — privately. Identity attestation via zero-knowledge proofs.
Provisioned on sign-up — the agent self-keys, the principal gets an email-provisioned wallet. Delegate to an agent without MetaMask or a seed phrase.
§ 07 — The mandate
Your AI will act.
Under whose rules?
Live on Base mainnet. No credit card. Three lines of code to put real limits on your agent, and a verifiable trail behind every decision it makes.
