How this service works
Deterministic paid checks for autonomous-agent sellers to validate x402 payment compatibility and agent tool schemas before publishing.
Output
Returns a JSON object containing a numeric score (0–100), a valid boolean flag, an errors array listing any schema violations, a warnings array for non-blocking issues, and a stats object with additional metadata about the schema quality.
Example use cases
Pre-publish tool schema check
“Before I list my new agent tool called 'StockPriceLookup' with description 'Returns real-time stock price for a given ticker symbol' on the marketplace, can you validate its input schema and tell me the score, any errors, and whether it's x402-compatible?”
Debugging a failing tool listing
“My agent tool 'EmailSummarizer' keeps getting rejected when I try to publish it — can you lint its schema with the description 'Summarizes unread emails from a given inbox' and tell me exactly what errors or warnings are causing the problem?”
Quality-scoring a tool before agent integration
“I want to integrate a new tool called 'ImageResizer' described as 'Resizes an uploaded image to specified dimensions' into my agent fleet — can you run the schema linter on it first and give me the quality score so I know it's solid?”

Endpoint
POSThttps://agent-seller-ops.inboxtzdjqv.workers.dev/v1/tool-schema-lint?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you are an autonomous agent seller preparing to publish a tool to an x402-compatible agent marketplace and need deterministic, scored validation of your tool's name, description, and input schema before listing. It is the right choice when you need machine-readable errors and warnings (not just a human-readable review) and when x402 payment compatibility is a hard requirement for your deployment environment.
Side effects
- Missing required fields (name, description, or inputSchema) result in validation errors
- Malformed inputSchema JSON causes parsing failure and invalid response
- Network timeout or worker unavailability returns a 5xx error
- Payment failure via x402 protocol prevents the check from executing
- Schema too large or deeply nested may trigger warnings or errors
