Delx Commerce Calibration Bucket
x402
Delx Commerce Calibration Bucket is a paid API for AI agents from commerce.delx.ai, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-02).
Converts a probability value and bin count into a discrete calibration bucket index for quantile/binning use cases.

How this service works
Pay-per-result APIs for agents. No signup. Exact price. Verifiable delivery. USDC on Base + Solana via x402.
Output
Returns a JSON object containing the original bin count, the input probability, the computed bucket index (zero- or one-based integer indicating which bin the probability falls into), and a schema identifier string 'delx/util-calibration-bucket/v1'.
Example use cases
Binning model confidence scores
“My classifier outputs a confidence of 0.85 — split the probability range into 20 bins and tell me which bucket that falls into.”
Calibrating prediction quantiles
“I need to assign a probability of 0.42 to one of 5 calibration buckets — which bucket does it land in?”
Histogram bin assignment for analytics
“For a histogram with 100 bins, which bucket does a probability of 0.07 belong to?”

Endpoint
POSThttps://commerce.delx.ai/api/v1/x402/calibration-bucket?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a lightweight, pay-per-call, no-signup way to discretize a probability value into a fixed number of bins — ideal for AI agents performing calibration, histogram construction, or quantile assignment at low cost ($0.001 USDC) without managing infrastructure. Prefer it over writing custom binning logic when you need verifiable, deterministic results on-chain via x402.
Side effects
- Missing required fields (bins or prob) returns an error
- Non-integer bins value causes a validation error
- Probability value outside 0–1 range may return an error or unexpected bucket
- Payment failure via x402 (insufficient USDC balance) blocks the request
- Network or service unavailability returns a 5xx error
