How this service works
Tool-Call Audit Pro: 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 report containing: audit tier (e.g. 'basic'), a verdict ('improved' or otherwise), baseline held-out test pass rate, improved held-out test pass rate, a recommended optimized system prompt, a recommended set of tools, the delta improvement in percentage points, and any remaining failure cases.
Example use cases
Customer support agent tool audit
“I have a customer support agent with a system prompt and 4 tools — search_kb, create_ticket, escalate_human, and send_email. Can you audit all of them and tell me how much better it would perform with your recommended changes?”
Coding assistant prompt optimization
“My coding assistant agent has a system prompt and 6 tools including run_code, lint_file, and search_docs. Can you benchmark its current tool-call accuracy and give me an upgraded system prompt and tool set that scores higher?”
Sales agent upgrade verification
“We're running a sales agent with 8 tools and I want to see a before-and-after pass rate report. Here's the system prompt and all the tool schemas — please give me the recommended improvements and the delta score.”
Technical details
Endpoint
POSThttps://a-upgradenet.com/x402/tool-call-audit-pro?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a data-driven, benchmarked audit of an AI agent's system prompt and tool definitions with a quantified before/after improvement score and concrete recommended replacements — rather than a generic prompt review or manual human evaluation.
Side effects
- Missing required 'system_prompt' or 'tools' fields returns a validation error
- Providing more than 12 tools violates schema maxItems constraint
- System prompt exceeding 8000 characters may be rejected or truncated
- Payment failure (x402) if USDC balance is insufficient
- Unsupported language value outside ['en','es'] enum causes rejection
