Delx Logit
x402
Delx Logit is a paid API for AI agents from api.delx.ai, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-19).
Converts a probability value (0–1) to its logit (log-odds) representation

How this service works
Logit transform log(p/(1−p)) for probability-space models. Call when featureizing probabilities for linear models offline. Returns logit value as deterministic JSON for $0.001 USDC via x402 on Base. First-party local math only—no RPC, live market feed, API keys, storage, or mediagen. Advisory only; the caller owns capital, risk, and production controls.
Output
Returns a JSON object containing the original probability (prob), the computed logit value (log(p/(1-p))), and a schema identifier string ('delx/util-logit/v1').
Example use cases
Calibrating ML model output scores
“I have a model outputting a probability of 0.9 — can you convert that to its logit value so I can feed it into a calibration layer?”
Log-odds for logistic regression pipeline
“Transform a probability of 0.3 into its log-odds (logit) so I can use it as an input feature for my logistic regression pipeline.”
Quick sanity check on predicted probability
“I predicted a 0.5 probability on this classifier output — what's the corresponding logit, just to sanity-check it's at zero?”
Technical details
Endpoint
POSThttps://api.delx.ai/api/v1/x402/logit?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a fast, paid-per-call micro-computation of the logit function without running your own math library — particularly useful in agent pipelines on the Delx platform where you are already making x402 micro-payments and want a governed, auditable computation step.
Side effects
- prob outside [0,1] range — logit is undefined; likely returns error or NaN
- prob exactly 0 or 1 — logit is negative or positive infinity, may cause numeric issues
- missing or non-numeric prob field — likely returns a validation or type error
