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 original probability, the computed logit value (natural log of prob/(1-prob)), and a schema identifier string ('delx/util-logit/v1').
Example use cases
Logistic regression feature preprocessing
“I have a probability score of 0.85 from my model output and I need to convert it to logit space before feeding it into a logistic regression — can you compute the logit for me?”
Calibration pipeline intermediate step
“As part of calibrating my classifier, I need the log-odds for a predicted probability of 0.6 — please compute the logit of 0.6.”
Explaining model confidence in log-odds terms
“My model returned a confidence probability of 0.92 — can you convert that to a logit value so I can interpret it as log-odds?”

Endpoint
POSThttps://commerce.delx.ai/api/v1/x402/logit?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a quick, cheap, verifiable logit (log-odds) computation without setting up authentication or a subscription. It is ideal for AI agents that need on-demand mathematical transformations within automated pipelines and want to pay per result in USDC via x402.
Side effects
- Probability value outside (0,1) range (e.g. 0 or 1) causes undefined or infinite logit — likely returns an error or NaN
- Missing 'prob' field in request body — likely 400 Bad Request
- Payment not attached or insufficient — 402 Payment Required response
- Probability exactly 0 or 1 causes log of zero — mathematically undefined
