// High-level guide for integrating your AI application with Adaline. Use when starting a new Adaline integration, choosing between API/SDK approaches, or planning which Adaline features to adopt.
Create and manage evaluation datasets in Adaline. Use when building test cases, adding dataset columns/rows, importing data, or triggering dynamic columns.
Fetch deployed prompt snapshots from Adaline at runtime. Use when integrating prompt deployments, environment-based latest lookups, prompt caching, or pinned deployment IDs.
Run and manage evaluations in Adaline to test prompt quality at scale. Use when creating evaluation runs, polling status, analyzing results, or cancelling runs.
Create and manage evaluators in Adaline to score prompt outputs. Use when setting up LLM-as-a-judge, JavaScript, text-matcher, cost, latency, or response-length evaluators.
Send traces and spans to Adaline for AI agent observability. Use when instrumenting LLM calls, tools, retrieval, embeddings, guardrails, or custom operations.
Create and manage prompts in Adaline via the v2 API or SDK clients. Use when programmatically creating prompts, updating prompt drafts, listing prompts, or reading prompt/playground data.

Adaline is the single platform to instrument, improve, define behaviors for, monitor, prompt, evaluate, and administer AI agents. It solves the AI Development Lifecycle (ADLC) — the end-to-end process of building, testing, shipping, and operating AI-powered applications.
Core pillars:
Set these environment variables when your Adaline credentials are available:
ADALINE_API_KEY — your workspace API key (from Settings > API Keys at app.adaline.ai)projectId — your project ID (from the dashboard sidebar)https://api.adaline.ai/v2You can start integrating before you have credentials. All code examples use placeholder values — replace them with real values when ready.
Choose the right skill based on your goal:
| Your goal | Skill to use | Approach |
|---|---|---|
| Send traces/spans from your app | adaline-logs | SDK (TS/Python) or REST API |
| Fetch deployed prompts at runtime | adaline-deployments | SDK or REST API |
| Create/manage prompts programmatically | adaline-prompts | REST API |
| Build evaluation datasets | adaline-datasets | REST API |
| Set up quality evaluators | adaline-evaluators | REST API |
| Run evaluations at scale | adaline-evaluations | REST API |
| Check available AI providers/models | adaline-providers | REST API |
Best for: Node.js and TypeScript applications. Provides typed namespace clients for the public API, helpers for deployed prompts, and buffered trace/span logging.
Install: npm install @adaline/client @adaline/api
Use for: logging, deployment fetching, and typed management operations for datasets, prompts, evaluators, evaluations, providers, models, projects, and logs.
Best for: Python applications. The current Python SDK is async-first: API calls and monitor.flush() are awaited inside an asyncio event loop.
Install: pip install adaline-client adaline-api
Use for: logging, deployment fetching, and typed management operations for datasets, prompts, evaluators, evaluations, providers, models, projects, and logs.
Best for: any language, serverless environments, custom integrations, and all management operations regardless of language. The SDK is a thin wrapper around this API.
Base URL: https://api.adaline.ai/v2
Authentication: Authorization: Bearer ADALINE_API_KEY
Best for: quick start with zero instrumentation code. Change your LLM client's base URL to gateway.adaline.ai — Adaline intercepts the request, forwards it to the provider, and automatically creates a trace and span. No SDK required.
Use this when you want observability immediately without modifying application code.
Work through these steps to get full value from Adaline:
adaline-logs — instrument your application to send traces and spans. This gives you immediate observability: latency, cost, errors, and prompt inputs/outputs visible in the dashboard.
adaline-deployments — move prompt text out of your code and into Adaline. Fetch the active deployed prompt at runtime using GET /deployments on the v2 API base URL. This decouples prompt changes from application code releases.
adaline-datasets — build datasets of representative inputs (and optionally expected outputs) for your use cases. These become the inputs to evaluations.
adaline-evaluators — define how to score prompt outputs: exact match, regex, JSON schema, or LLM-as-judge with a custom rubric.
adaline-evaluations — run a prompt version against a dataset using your evaluators. Use this as a quality gate before promoting a prompt to production.
adaline-providers — discover which LLM providers and models are configured in your Adaline workspace. Use this to avoid hardcoding provider IDs or model names.
| Variable | Required | Description |
|---|---|---|
ADALINE_API_KEY | Required | Bearer token for all API calls |
ADALINE_PROJECT_ID | Recommended | Project to associate logs with |
ADALINE_PROMPT_ID | Conditional | Required when fetching a deployed prompt |
ADALINE_DEPLOYMENT_ENVIRONMENT_ID | Conditional | Required when fetching environment-specific deployments (dev/staging/prod) |
Determine the right approach for your environment:
gateway.adaline.aiflush() or await the POST before the function returns to avoid losing buffered spansEvery REST request requires a Bearer token in the Authorization header:
Authorization: Bearer ADALINE_API_KEY
All request and response bodies are JSON. Timestamps in the public API are Unix milliseconds unless an endpoint explicitly says otherwise.
Retry strategy for REST API calls:
5xx server errors4xx client errors — these indicate a problem with the request or credentialsCommon errors:
| Status | Meaning | Action |
|---|---|---|
| 401 | Invalid or missing API key | Check ADALINE_API_KEY value |
| 403 | Key does not have access to this resource | Verify project membership and key permissions |
| 404 | Resource not found | Check IDs (projectId, promptId, datasetId, etc.) |
| 429 | Rate limited | Retry with exponential backoff |
| 400 | Validation error | Check request body against the skill's API reference |
| 500/502/503 | Server error | Retry with exponential backoff |
