x402
Delx Sign N 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).
Returns the mathematical sign of an integer value as -1, 0, or 1, along with the original value.

How this service works
Sign of a number (-1, 0, 1). Call when you branch agent logic on direction without float noise. Returns sign and original value 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
A JSON object containing the sign of the input integer (-1 for negative, 0 for zero, 1 for positive) and the original input value. No external network calls are made; computation is performed locally.
Example use cases
Branch agent logic on balance
“I need to know if the account delta of -150 is negative, zero, or positive so I can decide which workflow branch to take — can you get the sign of -150?”
Classify sensor reading direction
“My sensor just reported a value of 0 — can you tell me if that's positive, negative, or exactly zero so I know whether the device is active?”
Determine price movement direction
“The price change is 87 — can you compute the sign so I know whether to trigger the up, flat, or down handler in my pipeline?”
Technical details
Endpoint
POSThttps://api.delx.ai/api/v1/x402/sign-n?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a clean, noise-free sign classification of an integer without float rounding ambiguity — especially useful inside agent decision trees where branching on positive/negative/zero direction must be deterministic. Prefer over in-agent computation when auditability or consistent behavior across environments matters.
Side effects
- Non-integer or missing value input may return a validation error
- Floating-point values passed as integers may be rejected or truncated
- Payment failure via x402 will block the response
- Malformed JSON body results in a 400-level error
