How this service works
Tool-Call Audit Max: measures how an AI agent calls its tools on a hidden test, returns a fix that keeps the interface unchanged, and re-measures. Charged only after the report exists.
Output
Returns a JSON object with a tier label, completion status, and a detailed report including: baseline held-out pass rate and count, improved pass rate and count, delta points gained, a recommended system prompt, recommended tool list, and any remaining failures after the upgrade.
Example use cases
Improve customer support agent tool accuracy
“My customer support agent keeps failing to call the right tools — can you audit its system prompt and tool definitions and give me an upgraded version that performs better on held-out test cases?”
Benchmark new agent config before deployment
“Before I ship this new agent configuration, can you run an audit on its system prompt and these 8 tools, show me the baseline pass rate, and recommend improvements if the score is low?”
Debug low tool-call success rate
“My agent's tool-calling is only succeeding about half the time — please audit the system prompt and tool schemas I've set up and tell me what's failing and what the improved config would look like.”
Technical details
Endpoint
POSThttps://a-upgradenet.com/x402/tool-call-audit-max?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a quantified, benchmark-backed audit of an agent's system prompt and tool definitions, not just a qualitative review. It is especially valuable when you want a drop-in recommended upgrade (new system prompt + tool list) with a measurable improvement score, rather than generic prompt engineering advice. Prefer it over manual review when you have up to 12 tools and want held-out test pass rates before and after the upgrade.
Side effects
- System prompt exceeds 8000 characters — request rejected
- Tools array is empty or exceeds 12 items — validation error
- Missing required fields (name or parameters) in a tool definition — schema validation failure
- Payment not received or insufficient USDC — 402 response
- Language enum value not recognized — request rejected
- Service unavailable or benchmark timeout — no report returned
