Framework Integrations

Make your AI agents verifiable by integrating Beltic's HTTP request signing into popular agent frameworks. When your agent calls external APIs, those services can verify the request came from a trusted, verified agent.

Why Sign Agent Requests?

When AI agents interact with external services, those services need to answer a critical question: "Can I trust this agent?"

Beltic solves this by providing:

1. Verifiable Identity - Each agent has cryptographic credentials tied to a verified developer
2. Request Signing - Every HTTP request is signed with the agent's private key
3. Trust Chain - Services can verify the full chain: Agent → Developer → Beltic Platform

Integration Patterns

Quick Example

Here's the core pattern - wrap HTTP requests with Beltic signing:

import { signHttpRequest, importPrivateKey } from '@belticlabs/agent-signer';

async function signedFetch(url: string, options: RequestInit = {}) {
  const privateKey = await importPrivateKey(process.env.AGENT_PRIVATE_KEY!, 'EdDSA');

  const signedHeaders = await signHttpRequest({
    method: options.method || 'GET',
    url,
    headers: options.headers as Record<string, string>,
    body: options.body as string,
    privateKey,
    keyId: process.env.AGENT_KEY_ID!,
    keyDirectoryUrl: process.env.AGENT_KEY_DIRECTORY_URL!,
  });

  return fetch(url, {
    ...options,
    headers: { ...options.headers, ...signedHeaders },
  });
}

Prerequisites

Before integrating with any framework, you'll need:

1. Beltic CLI installed - brew install belticlabs/tap/beltic
2. Agent credentials - Run beltic login and create an agent
3. Keypair - Run beltic keygen to generate signing keys
4. Key directory hosted - Your agent's public key must be accessible via HTTPS

See the CLI Guide for detailed setup instructions.
