DESCRIPTION

Turns a raw agent execution trace into a readable agent trace summary: an ordered step-by-step account of what the agent did, where it broke, and why. Built for tool call debugging when a run fails silently or an agent loops without explanation: send the trace array or log and get back failure points plus a root-cause hypothesis grounded only in what the trace actually shows, with anything it can't determine labeled unknown instead of guessed. Useful for agent run analysis after an incident, before a retry, or as part of a CI check on agent behavior. Use it as an agent debugging API, a trace root cause tool, or a post-mortem generator for agent pipelines.

EXAMPLES — two ways to call
EXAMPLE 1 · curl
curl -X POST https://x402.agentutility.ai/agent-trace-brief \
  -H 'Content-Type: application/json' \
  -d '{ }'
first response = 402 Payment Required with payment requirements; sign + retry with X-PAYMENT.
EXAMPLE 2 · mcp
# Install the MCP package for this endpoint's cluster
npx -y @agentutility/mcp-<cluster>

# Required: EVM private key with USDC on Base
export X402_PRIVATE_KEY=0x...

# Then call the agent-trace-brief tool from your MCP-aware agent.
MCP server handles payment automatically — your coding agent just calls the tool by name.
