How this service works
x402-paid Solana mainnet wallet preflight oracle for agents.
Output
A JSON object with an 'ok' boolean, an 'errors' array listing validation failures (e.g. missing payTo, malformed accepts), a 'warnings' array for non-blocking issues (e.g. missing mimeType), and a 'summary' object containing detected assets, networks, and minimum USDC amount.
Example use cases
Debug missing payTo field
“My x402 paid API calls keep failing — can you lint this payment config object and tell me what fields are missing or wrong? The accepts array doesn't seem to have a payTo address set.”
Preflight check before agent deployment
“Before I deploy my agent that uses x402 payments on Solana mainnet, run a preflight validation on my payment configuration and list any errors or warnings so I can fix them first.”
Validate USDC amount and network settings
“Can you validate my x402 config to confirm the min USDC amount and network are correctly specified for Solana mainnet? I want to make sure the summary fields look right before going live.”
Technical details
Endpoint
POSThttps://home.chrz.dev/agent-dust/v1/agent/x402-lintWhen to prefer
Use this endpoint when you need to validate an x402 payment configuration object before submitting a paid request on Solana mainnet — particularly useful during agent development, CI/CD pipelines, or when debugging why x402 payments are being rejected. Prefer this over trial-and-error live calls since it costs only $0.005 USDC and returns actionable error messages without triggering actual payment flows.
Side effects
- Malformed request body returns validation errors in the errors array with ok=false
- Missing required fields in accepts array surfaced as specific error strings
- Non-fatal issues like missing mimeType returned as warnings rather than errors
- Network connectivity issues may return HTTP-level errors
- Invalid JSON input may cause a 400-level response
