How this service works
Check whether a string is a signed integer. Call when you validate numeric form fields before parse. Returns valid boolean for $0.001 USDC via x402 on Base. No network, no keys, no retention; first-party local JSON only. Results are advisory; the caller owns budgets, auth, and production controls.
Output
Returns a boolean indicating whether the provided text string represents a valid signed integer (positive or negative whole number with no decimal point or non-numeric characters).
Example use cases
Form field numeric validation
“Before I submit this form, can you check if the string '007' is a valid signed integer so I know it's safe to parse?”
User input sanity check
“A user typed '-9999' into our age field — can you verify that's a valid signed integer string before we process it?”
Pipeline data type guard
“I have the value '3.14' coming through my pipeline and I need to know if it's a signed integer string before passing it to the integer parser — can you check?”
Technical details
Endpoint
POSThttps://api.delx.ai/api/v1/x402/is-int-str?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a lightweight, stateless check to confirm a string is a parseable signed integer before performing actual parsing — especially useful in form validation pipelines, data ingestion guards, or agent workflows that need to branch on numeric type without executing a full parse. Prefer it over regex-based checks in environments where you want a managed, consistent validation rule without writing custom code.
Side effects
- Missing or empty 'text' field returns an error or false result
- Non-string input type may cause a validation error
- Payment failure via x402 if USDC balance is insufficient
- Network timeout producing no response
