Protocol

01 — Settlement

Instant agent-to-agent payments

Arch provides automated settlement rails so agents can pay each other for work, data, and compute without human checkpoints. Sub-50ms finality, cryptographic receipts.

arch.settle({
  from: "agent:orchestrator-7f2a",
  to:   "agent:retriever-b3c1",
  amount: 0.00142,
  unit:  "COMPUTE",
  proof: task.computeProof,
});

02 — ComputeProof

Verified work, not assumed trust

Every FLOP is attested on-chain. ComputeProof tokens are issued after cryptographic verification of AI useful work, making compute the unit of account across your pipeline.

const proof = await arch.verify({
  model:  "gpt-4o",
  flops:  task.reportedFlops,
  output: task.hash,
});
// proof.verified === true
// proof.token → "cpt_0x4f2a..."

03 — AgentRank

Identity and quality scoring

AgentRank builds a verifiable reputation for every agent in your network. Orchestrators can route work to high-ranked agents and refuse service from unknowns.

const agent = await arch.agents.get(
  "agent:retriever-b3c1"
);
// agent.rank     → 94.7
// agent.verified → true
// agent.settled  → 1_204 txns

How it works

1

Install the SDK

Add the Arch package and drop in your API key. Zero config required.

2

Instrument your agents

Wrap task calls with arch.settle() and arch.verify(). No pipeline restructure needed.

3

Watch the economy run

Your dashboard fills with live settlement flows, compute attestations, and agent scores.

Developers

One key.
Full visibility.

Instrument your multi-agent stack with a single Arch API key. Every settlement, compute attestation, and agent identity flows into your dashboard automatically. No schema migrations, no new infrastructure.

  • →SDK available for Python, TypeScript, and Go
  • →OpenAPI spec for direct HTTP integration
  • →Webhook events for every settlement
  • →Sandbox environment for testing
quickstart.ts
import Arch from "@arch-protocol/sdk";

const arch = new Arch({
  apiKey: process.env.ARCH_API_KEY,
});

// Register your agent
const agent = await arch.agents.register({
  id:   "agent:my-retriever",
  type: "retrieval",
  model: "gpt-4o-mini",
});

// Settle a task payment
const tx = await arch.settle({
  from:   agent.id,
  to:     "agent:orchestrator",
  amount: agent.lastTask.cost,
  proof:  agent.lastTask.computeProof,
});

console.log(tx.id); // txn_0x7f2a...

Arch is in private design and IP protection phase. Enterprise teams building multi-agent infrastructure get first access when rails go live.
