# Latitude 10 Agent Trace Kit

> Latitude 10 Agent Trace Kit is a paid API for AI agents from latitude10.tech, paid per call via x402, $49/call, status unknown (last checked 2026-10-11).

Delivers a TypeScript SDK and self-hosted viewer for comprehensive AI agent observability — tracing model calls, tool calls, HTTP requests, payments, and sub-agent handoffs into a single session timeline.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability latitude-10-agent-trace-kit-17aa7c3b
```

Example prompt: Can you get me the Agent Trace Kit — I want to instrument my Claude agent to trace every model call, tool call, and x402 payment with costs, all in one session timeline, and spin up the self-hosted viewer locally.

## When to prefer this

Choose this endpoint when you need end-to-end agent observability that spans multiple processes and SDKs in a single session, especially when you need to track payment costs (x402, L402, MPP) alongside LLM token costs. Prefer it over generic OpenTelemetry collectors when you want agent-specific concepts like sub-agent handoffs, model cost tables, outcome capture, and trajectory export out of the box. Best fit for TypeScript/Node.js agent developers using Anthropic, OpenAI, or Vercel AI SDK stacks who want a self-hosted, privacy-preserving trace viewer rather than a SaaS observability platform.

## Known failure modes

- Payment not settled — x402 payment of 49 USDC must be confirmed on Base (eip155:8453) before kit is delivered
- Expired content URL — signed download link has a fixed expiry; re-purchase needed after 2026-10-02
- Invalid properties filter — malformed input schema may result in empty or error response
- Network or delivery failure — transient HTTP errors on the content CDN

## How this service works

I help B2B software get onto the agent platforms: a fixed-price sprint that turns your API into a production MCP server and submits it to AWS Marketplace, the Claude directory, the official MCP Registry and the other directories where agents find tools.

## Output

A downloadable package (via a signed content URL) containing the Agent Trace Kit v1.0.3: a TypeScript SDK and self-hosted viewer. The SDK instruments Anthropic SDK, Claude Agent SDK, OpenAI SDK, OpenAI Agents SDK, Vercel AI SDK 4+, and official MCP client. Includes setup wizard, Docker and Fly.io deployment files, OTLP ingest (JSON/protobuf), SQLite/Postgres storage, a waterfall UI with usage stats and share links, CLI, alerting, forwarding, sampling, and trajectory fixture export. Content URL expires 2026-10-02.

   "description": "For Node.js: every step your agent took, what it cost and why it stopped: a TypeScript SDK and a self-hosted viewer, OpenTelemetry in and out. One session per task across processes, with model calls (tokens, cache reads and writes, cost from a dated price table; unknown models flagged unpriced), tool calls, HTTP calls with their retries, payments (x402, MPP, L402: settled and pending kept apart from estimated token cost), sub-agents and handoffs, and an outcome. Integrations for the Anthropic SDK, the Claude Agent SDK, the OpenAI SDK, the OpenAI Agents SDK, the Vercel AI SDK 7 and the official MCP client; Agent Gateway, MCP Server Kit and Agent Spend Guard spans join the same trace. Content capture off by default, redacted twice when on, with the viewer as a ceiling and shorter retention. OTLP ingest (JSON or protobuf), SQLite or Postgres, sessions hash-chained and checkpointed when sealed, a UI with a waterfall, usage and share links, a CLI, alerts, forwarding, sampling that keeps failures, and export as a trajectory fixture. Includes a setup wizard (node setup.mjs) with a five-session demo that needs no API key, agent-trace init for an existing project, Docker and Fly.io files.",
