# AI Agent Trace Analyzer

> AI Agent Trace Analyzer is a paid API for AI agents from api.strale.io, paid per call via x402, $0.216001/call, status unknown (last checked 2026-10-11).

Analyzes AI agent execution traces from LangChain, CrewAI, or AutoGen to identify failure points, root causes, token waste, and suggest fixes

## 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 api-strale-io-5b79eaba
```

Example prompt: Can you analyze this agent trace log and tell me where it failed, why it wasted tokens, and how to fix it? Here's the trace output: [paste LangChain/CrewAI/AutoGen log here].

## When to prefer this

Use this endpoint when you have a raw execution trace or log from a LangChain, CrewAI, or AutoGen agent run and need automated diagnosis of what went wrong, where tokens were wasted, and how to fix the issues — especially useful for debugging agent loops, tool call failures, or unexpectedly high token consumption.

## Known failure modes

- Empty or malformed trace string returns parsing error
- Trace from unsupported framework may produce incomplete analysis
- Very long traces may be truncated or return partial results
- Missing required 'trace' query parameter returns 400 validation error

## How this service works

Analyze AI agent execution traces (LangChain/CrewAI/AutoGen). Identifies failure points, root causes, token waste, and suggests fixes.

## Output

Returns a structured diagnostic report identifying specific failure points in the agent execution, root causes of errors or loops, quantified token waste, and actionable fix recommendations tailored to the agent framework used.
