## How it works

1. **Link your customer's LangChain account.** Use Truto's frontend SDK; we handle every OAuth and API key flow so you don't need to create the OAuth app.
2. **Authentication is automatic.** Truto refreshes tokens, stores credentials securely, and injects them into every API request.
3. **Call Truto's API to reach LangChain.** The Proxy API is a 1-to-1 mapping of the LangChain API.
4. **Get a unified response format.** Every response uses a single shape, with cursor-based pagination and data in the `result` field.

## Use cases

- **Embed LLM observability into your AI-powered SaaS** — Let your customers connect their LangSmith workspace so traces, runs, and thread-level analytics from your AI features flow into their existing LLMOps stack. Removes the need for them to manually wire up SDKs or maintain duplicate observability infrastructure.
- **Close the feedback loop from your product to prompt engineers** — Capture thumbs-up/down, edits, and corrections your end users make on AI-generated content and push them as structured feedback tied to LangSmith run IDs. Gives your customers' AI teams real production signal to fine-tune prompts and models.
- **Route low-confidence AI outputs into human review queues** — When your AI agent fails or produces low-confidence responses, automatically push those runs into your customer's LangSmith annotation queues for human-in-the-loop grading. Lets QA and prompt teams triage failures without leaving their existing review workflow.
- **Surface AI cost and usage inside FinOps dashboards** — Pull granular billing, token usage, and thread stats from LangSmith into your financial analytics or cloud cost platform. Enterprises can then unify LLM spend with the rest of their infrastructure budget and set programmatic usage limits.
- **Sync ground-truth datasets between your app and LangSmith** — Let users promote real interactions from your platform (support tickets, generated docs, chat transcripts) into LangSmith datasets as test examples. Makes it trivial for your customers to build evaluation suites from actual production edge cases.

## What you can build

- **Two-way feedback sync on AI outputs** — Post user ratings, comments, and corrections to LangSmith feedback endpoints keyed by run ID, and read existing feedback back to display quality signals in your UI.
- **Automated annotation queue population** — Create annotation queues and push runs into them programmatically when your app detects hallucinations, low confidence, or negative user reactions.
- **Dataset and example management UI** — Give users an in-app interface to create datasets, bulk-upload examples, manage dataset splits, and trigger dataset runs without opening the LangSmith console.
- **Embedded trace and thread explorer** — Fetch runs, thread traces, and thread stats to render step-by-step agent execution, latency, and token cost views natively inside your product.
- **Workspace and API key provisioning** — Let users create workspaces, mint scoped API keys or service keys, and configure TTL and usage limits per tenant during onboarding to your integration.
- **Prompt and experiment CI hooks** — Trigger experiment runs, comparative experiments, and platform evaluators from your CI/CD or release workflow, then pull results back to gate deploys.

## FAQs

### What LangChain product does this integration actually talk to?

The integration targets the LangSmith API — the commercial LLMOps platform in the LangChain ecosystem. It covers runs, traces, threads, feedback, datasets, examples, annotation queues, workspaces, evaluators, and billing/usage data.

### How does authentication work for end users?

End users connect by providing a LangSmith API key or service key scoped to their workspace or organization. Truto stores and rotates the credential per connected account, so your app never handles raw secrets in code.

### Can I write feedback back to specific LangSmith runs?

Yes. You can create, update, and delete feedback tied to a specific run ID, including scores, comments, and correction values. Bulk and public feedback endpoints are also supported for higher-throughput use cases.

### Does the integration support multi-tenant workspaces?

Yes. You can list, create, and manage LangSmith organizations and workspaces, provision members, set per-workspace TTL and usage limits, and issue scoped service keys — which is essential when your customers separate environments or client tenants.

### What data is available for cost and usage reporting?

You can list billing usage, granular usage, and workspace usage limits, plus thread stats and run-level token/latency metrics. This is enough to build cost dashboards, chargeback reports, and automated spend guardrails.

### Can I manage datasets and evaluations programmatically?

Yes. The integration exposes datasets, dataset versions, examples (including bulk create/update/delete and uploads), dataset splits, comparative experiments, and platform evaluators, so you can build full evaluation workflows and CI checks on top.

### Are annotation queues and human-in-the-loop workflows supported?

Yes. You can create annotation queues, populate them with runs, list and update queue items, add reviewers, and export results — enough to build a custom labeling UI backed by LangSmith.
