x402
Delx Is Float String is a paid API for AI agents from api.delx.ai, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-21).
Checks whether a given string represents a valid floating-point number, returning a boolean result.

How this service works
Check whether a string is a float. Call when you validate decimal 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 is a valid floating-point number (true if it can be parsed as a float, false otherwise).
Example use cases
Form field validation before submission
“The user just typed '12.abc' into the price field — can you check if that's a valid float before I try to parse it and send the order?”
CSV data cleaning pipeline
“I'm processing a CSV and the value in the 'amount' column is '0.0075' — can you verify it's a valid float so I know it's safe to parse?”
Agent input sanitization
“Before passing the user-supplied measurement '−9.81' to my physics calculator, check whether it's actually a valid floating-point string.”
Technical details
Endpoint
POSThttps://api.delx.ai/api/v1/x402/is-float-str?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a fast, dependency-free float validation check inside an agent pipeline without writing custom regex or parser logic. Ideal for pre-validation of user-supplied decimal inputs (form fields, CSV values, API parameters) before attempting numeric conversion. Best suited for single string checks at minimal cost ($0.001 USDC).
Side effects
- Missing or empty 'text' field returns an error or false
- Non-string input types may cause schema validation errors
- Network timeouts on the paid x402 endpoint
- Payment failure if USDC balance is insufficient on Base
