# Strale Agent Trace Analyzer

> Strale Agent Trace Analyzer is a paid API for AI agents from api.strale.io, paid per call via x402, $0.216/call, status unknown (last checked 2026-10-12).

Analyzes agent log/trace output to evaluate behavior, detect anomalies, and return a cryptographically-audited trace analysis record

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 strale-agent-trace-analyzer-89fb981d
```

Example prompt: Can you analyze this agent trace log and tell me if anything looks off or anomalous? Here's the trace output: '[AGENT] Step 1: retrieved user query... Step 2: called tool search_web... Step 3: returned answer...'

## When to prefer this

Choose this endpoint when you need cryptographically audited, tamper-evident analysis of AI agent traces — especially in compliance, safety, or multi-agent orchestration contexts where you need a verifiable record of what an agent did and why. Prefer this over generic log analysis tools when you need the audit chain hashing guarantee and structured behavioral evaluation specific to AI agent execution patterns.

## Known failure modes

- Missing or empty 'trace' query parameter returns a 400 validation error
- Malformed or unrecognizable trace format may yield low-confidence or incomplete analysis
- Very long trace strings may be truncated or time out
- Payment failure or insufficient USDC balance returns a 402 response
- Non-GET HTTP method returns a 405 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 analysis of the provided agent trace, including detected steps, behavioral flags, anomaly indicators, and a cryptographic audit record with chain hashing for tamper-evident logging.
