How this service works
Pay-per-result APIs for agents. No signup. Exact price. Verifiable delivery. USDC on Base + Solana via x402.
Output
A JSON object containing the sign of the input integer (-1 for negative, 0 for zero, +1 for positive), the original input value, and a schema identifier string 'delx/util-sign-n/v1'.
Example use cases
Classify numeric value sign
“Tell me whether the number -7 is positive, negative, or zero — give me the sign as -1, 0, or 1.”
Validate sign before conditional logic
“I need to know the sign of the integer 0 before I branch my workflow — is it -1, 0, or +1?”
Test micropayment API integration
“Run a quick sign-of-number check on the value 99 to verify the x402 pay-per-result pipeline is working end to end.”
Technical details
Endpoint
POSThttps://commerce.delx.ai/api/v1/x402/sign-n?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a verifiable, pay-per-result mathematical sign computation with no signup overhead, especially in agent pipelines that already use the x402 micropayment protocol on Base or Solana. Prefer it over implementing signum logic inline when auditability and verifiable delivery of results matter.
Side effects
- Missing or invalid 'value' field returns an error
- Non-integer input may cause validation failure
- Payment failure via x402 prevents execution
- Network timeout on Base or Solana payment settlement
