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 input integer n, the computed factorial value as an integer, and a schema identifier string (e.g. 'delx/factorial/v1') confirming the result format and provenance.
Example use cases
Combinatorics count in agent pipeline
“I need to know how many ways I can arrange 8 items — can you compute 8 factorial for me?”
Verifying large factorial in crypto workflow
“Compute the factorial of 20 and give me the exact value — I need it verified and delivered on-chain.”
Quick math check for a student
“What is 15 factorial? Just give me the exact number.”
Technical details
Endpoint
POSThttps://commerce.delx.ai/api/v1/x402/factorial?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a trustless, pay-per-result factorial computation with no signup, verifiable delivery, and micropayment via USDC on Base or Solana. Ideal for AI agent pipelines that need auditability and on-chain payment receipts rather than a free, unverifiable computation.
Side effects
- n is negative — factorial undefined for negative integers
- n is too large — integer overflow or out-of-range for allowed input
- n is not an integer — type validation error
- payment failure — insufficient USDC balance or x402 payment not accepted
- missing required field n — request body validation error
