Tool Call Diff

Deterministic tool call diff between two agent run sequences.

Overview

Deterministic tool call diff between two agent run sequences. Send before and after arrays of tool calls (name/args or tool/arguments shape) and get back which calls were added, removed, or reordered, plus per-call argument drift with the exact changed argument paths from a deep compare. No LLM involved, so results are exact and reproducible: the same replay comparison always returns the same diff. Built for agent regression diff work: confirming a prompt or code change didn't silently alter which tools an agent calls or what it passes them. Use it as a tool call diff API, an agent action drift checker, or a replay comparison step in CI before shipping an agent change.

How to call it

Requests are paid per call over the x402 protocol. Call the endpoint, receive a 402 Payment Required quote, then repeat the request with the signed payment header. The SDKs do both steps for you.

# 1. Ask for a quote
curl -i -X POST https://api.jarvisclaw.ai/v1/marketplace/api/tool-call-diff \
  -H 'Content-Type: application/json' \
  -d '{}'

# 2. Pay it (the SDK signs and retries for you)
curl -X POST https://api.jarvisclaw.ai/v1/marketplace/api/tool-call-diff \
  -H 'Content-Type: application/json' \
  -H 'X-PAYMENT: <signed-payload>' \
  -d '{}'
