The API-First Approach to AI Agent Trust

(No Blockchain Experience Required)

Most AI developers don’t want to become blockchain experts just to prove their agents are trustworthy. Managing wallets, gas fees, and on-chain transactions shouldn’t be a prerequisite for building great AI.

That’s exactly the problem ETHYS solves.

Instead of forcing developers to learn blockchain complexity, we handle everything behind the scenes. You just send simple JSON payloads, and we take care of the rest.

The Problem: Blockchain is Hard

Traditional agent trust systems require developers to:

  • Create and manage ETH wallets

  • Handle gas fees and transaction failures

  • Deploy and interact with smart contracts

  • Implement cryptographic signatures

  • Monitor blockchain state and confirmations

For most AI developers, this is onerous - too much complexity for what should be simple trust tracking.

The ETHYS Solution: Simple APIs

Instead of blockchain complexity, ETHYS gives you simple REST endpoints.

Here’s everything you need to do:

Step 1: Get Your API Key

Generate an API key from your Ethys dashboard in 30 seconds. That’s it - no wallet creation, no gas fees, no blockchain setup.

Step 2: Register Your Agent

Clicks “Create Agent”

• Fills out form with name, capabilities, metadata

• ETHYS auto-generates agentId and creates custodial wallet for your agent

Step 3: Send Performance Data

// Just send your agent's performance data
const telemetry = await fetch('https://api.ethys.io/v1/telemetry', {
  method: 'POST', 
  headers: {
    'Authorization': `Bearer ${ETHYS_API_KEY}`,
    'Content-Type': 'application/json'
  },
  body: JSON.stringify({
    agentId: "customer-support-bot-v1",
    batch: [
      {
        timestamp: 1703123456,
        type: "task", 
        data: {
          operation: "customer_inquiry",
          duration: 2300,
          outcome: "resolved",
          customerSatisfaction: 4.8
        }
      },
      {
        timestamp: 1703123460,
        type: "success",
        data: {
          status: 200,
          responseTime: 2100
        }
      }
    ],
    metadata: {
      runtime: "node-18.17.0",
      host: "support-server-1", 
      version: "1.0.0"
    }
  })
});

Step 4: Read Trust Scores

// Get your agent's trust score instantly
const trustScore = await fetch(`https://api.ethys.io/v1/trust/score?agentId=customer-support-bot-v1`, {
  headers: {
    'Authorization': `Bearer ${ETHYS_API_KEY}`
  }
});

const score = await trustScore.json();
// Returns: { agentId: "...", rs: 85.2, ci: 78.9, updatedAt: "..." }

That’s it. No blockchain complexity, no wallet management, no gas fees.

What Ethys Handles Behind the Scenes

While you’re sending simple JSON, here’s what we’re doing automatically:

Wallet Management: Auto-create agent wallets with secure key storage
Blockchain Transactions: Submit trust updates to Base blockchain
Gas Fees: Pay all transaction costs from our treasury
ERC-8004 Compliance: Maintain full standard compliance
Cryptographic Signatures: Handle all signature verification
Mathematical Trust Scoring: Calculate RS and CI using proprietary algorithms

The Value: Focus on Building, Not Blockchain

With ETHYS, developers can:

Focus on AI: Build better agents instead of learning blockchain
Ship Faster: No blockchain setup delays
🔒 Trust Mathematics: Real trust scoring, not marketing claims
🔗 Stay Compliant: Automatic ERC-8004 compliance
