Delx Commerce — Integer String Validator

Choose this endpoint when you need a lightweight, pay-per-call, no-signup check on whether a text value is a valid integer string — especially useful in agent pipelines where you want verifiable, auditable validation without deploying your own logic or maintaining infrastructure. Ideal for micro-validation steps in agentic workflows paid in USDC via x402.

• Missing or empty 'text' field in request body — likely returns an error or unexpected result
• Non-string input type may cause parsing failure
• Network or payment failure via x402 protocol before result is delivered
• Edge cases like very large numbers, leading zeros, or special formats (e.g. hex) may return unexpected validity judgments
