Quick Start

The SDK uses a unified Scope3Client with a persona parameter to determine available resources.

Buyer Persona

For programmatic advertising -- manage advertisers, bundles, campaigns, and signals.

import { Scope3Client } from 'scope3';

const client = new Scope3Client({
  apiKey: process.env.SCOPE3_API_KEY!,
  persona: 'buyer',
});

// List advertisers
const advertisers = await client.advertisers.list();

// Create a bundle for inventory discovery
const bundle = await client.bundles.create({
  advertiserId: 'adv-123',
  channels: ['display', 'video'],
});

// Discover products in the bundle
const products = await client.bundles.discoverProducts(bundle.data.bundleId);

// Add products to the bundle
await client.bundles.products(bundle.data.bundleId).add({
  products: [{ productId: 'prod-1', salesAgentId: 'sa-1', groupId: 'g-1', groupName: 'Group 1' }],
});

// Create and execute a discovery campaign
const campaign = await client.campaigns.createDiscovery({
  advertiserId: 'adv-123',
  bundleId: bundle.data.bundleId,
  name: 'Q1 Campaign',
  flightDates: { startDate: '2025-01-15', endDate: '2025-03-31' },
  budget: { total: 50000, currency: 'USD' },
});
await client.campaigns.execute(campaign.data.id);

Partner Persona

For partner and agent management.

const partnerClient = new Scope3Client({
  apiKey: process.env.SCOPE3_API_KEY!,
  persona: 'partner',
});

// List partners
const partners = await partnerClient.partners.list();

// Register an agent
const agent = await partnerClient.agents.register({
  name: 'My Agent',
  type: 'SALES',
  partnerId: 'partner-123',
});

Configuration

const client = new Scope3Client({
  apiKey: 'your-api-key',       // Required: Bearer token
  persona: 'buyer',              // Required: 'buyer' | 'partner'
  environment: 'production',     // Optional: 'production' (default) | 'staging'
  baseUrl: 'https://custom.com', // Optional: overrides environment
  adapter: 'rest',               // Optional: 'rest' (default) | 'mcp'
  timeout: 30000,                // Optional: request timeout in ms
  debug: false,                  // Optional: enable debug logging
});

Updating the SDK When the API Changes

The SDK is manually maintained. When the Agentic API changes, update these files:

What changed	Files to update
Request/response shapes	src/types/index.ts
Endpoints added/removed	src/resources/ (the relevant resource class)
CLI commands	src/cli/commands/ (the relevant command file)
Bundled skill.md	src/skill/bundled.ts (copy from API response)

Steps:

1. Check the latest skill.md for your persona:

   curl https://api.agentic.scope3.com/api/v2/buyer/skill.md
   curl https://api.agentic.scope3.com/api/v2/partner/skill.md

2. Compare against src/skill/bundled.ts and update if needed
3. Update types in src/types/index.ts to match any schema changes
4. Update resource methods in src/resources/ for endpoint changes
5. Update CLI commands in src/cli/commands/ if applicable
6. Run npm test and npm run build to verify
7. Run manual workflow tests: npm run test:buyer, npm run test:partner

Integration Tests

export SCOPE3_API_KEY=your_key
npm run test:buyer     # Buyer workflow
npm run test:partner   # Partner workflow
npm run test:all       # All workflows
