What is Phantom?
Phantom is a hypothetical developer platform designed to accelerate the creation, testing, and deployment of modern applications that interact with distributed services. At its core Phantom provides a set of modular SDKs, a predictable API surface, tooling for local dev and CI/CD, and a secure runtime environment. This introduction is intended for engineers who will build integrations, SDKs, or platform-aware applications — whether you are writing a microservice, a CLI tool, or a UI plugin.
Core Concepts
Understanding the core concepts of Phantom helps you design integrations that are resilient and maintainable. Below are the primary building blocks:
1. SDKs and Clients
Phantom provides first-class SDKs in multiple languages. Each SDK is a thin wrapper over the platform's HTTP/GRPC API and focuses on developer ergonomics: typed responses, helpers for retries, and built-in telemetry. Use SDKs for quick prototyping; use direct HTTP calls when you need fine-grained control.
2. Authentication and Secrets
All Phantom APIs require authenticated requests. Authentication is token-based and supports short-lived tokens for CI credentials and long-lived tokens for service-to-service integration. Secrets are never stored in plain text — use the Phantom Secrets API or your environment manager to inject credentials at runtime.
3. Events and Webhooks
Phantom emits events to signal state changes (builds, deployments, incoming messages). Webhooks are the preferred integration method for asynchronous reactions. Implement idempotency in your webhook handlers to avoid duplicate effects.
Getting started
This quickstart assumes you have a Phantom account and a project created via the dashboard. Follow these steps to run a simple example using the Phantom CLI.
Install the CLI
npm install -g @phantom/cli
phantom login
phantom init my-sample-app
cd my-sample-app
phantom start
Create your first integration
Scaffold a basic integration that receives events and posts responses. Keep the handler logic small and test locally using the CLI's replay tools.
Architecture
Phantom's architecture is modular and layered. At a high level: clients & SDKs → API gateway → service mesh → core services (auth, events, storage) → durable backends. This separation ensures that teams can evolve independently and that the platform scales horizontally.
Design patterns
When integrating with Phantom, prefer event-driven patterns for long-running flows and request-response for immediate queries. Use exponential backoff for retryable errors and circuit breakers for third-party systems to prevent cascading failures.
API overview
The API surface includes endpoints for authentication, resources (projects, deployments), telemetry, and secrets. Responses are JSON and follow a consistent envelope format that includes metadata, pagination hints, and standardized error objects.
Example: Create a deployment
POST /v1/projects/{projectId}/deployments
Authorization: Bearer <TOKEN>
Content-Type: application/json
{
"name": "my-deploy",
"image": "ghcr.io/myorg/myapp:latest",
"env": {"NODE_ENV":"production"}
}
Response
{
"id":"deploy_01F...",
"status":"queued",
"created_at":"2025-10-10T12:00:00Z"
}
Best practices
Security, observability, and simplicity are the three pillars of successful Phantom integrations:
- Rotate tokens and minimize scopes for least privilege.
- Emit structured logs and attach correlation IDs for traces.
- Prefer configuration over code for environment differences.
- Write small unit tests for handler logic and integration tests for end-to-end flows.

Conclusion
Phantom aims to simplify building production-ready integrations by providing cohesive tooling and thoughtful APIs. As you adopt Phantom, focus on small iterations, automated tests, and observable operations. With these foundations, you can deliver reliable features faster and reduce operational overhead.
