Delx Calibration Bucket
x402
Delx Calibration Bucket 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).
Maps a probability value to a discrete bucket index given a specified number of bins, useful for histogram-style binning in agent pipelines.

How this service works
Bucket a probability into a calibration bin for reliability charts. Call when building simple calibration histograms from many forecasts. Returns bucket index and bounds 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 echoed bins and prob inputs alongside a zero-based integer bucket index indicating which bin the probability falls into, plus a schema identifier string (e.g. delx/util-calibration-bucket/v1).
Example use cases
Routing agent decisions by confidence tier
“My model returned a confidence score of 0.85 and I want to route it into one of 5 decision tiers — which bucket does 0.85 fall into across 5 bins?”
Histogram slot assignment for analytics
“I'm building a histogram of model output probabilities using 20 bins — can you tell me which bin a probability of 0.42 belongs to?”
Threshold-based workflow branching
“I need to classify a probability of 0.61 into one of 8 calibration buckets so my agent can branch to the right handler — what bucket index does that give me?”
Technical details
Endpoint
POSThttps://api.delx.ai/api/v1/x402/calibration-bucket?utm_source=zero.xyzWhen to prefer
Use this endpoint when an agent needs to discretize a continuous probability or confidence score into a fixed number of integer bins — for example, to route downstream logic, build histogram tallies, or tier model outputs into categories. Prefer this over implementing custom bucketing logic inline when operating in a Delx-native agent pipeline where deterministic, schema-versioned utility calls are preferred for auditability.
Side effects
- Missing required field bins or prob returns a 4xx validation error
- prob values outside [0, 1] may yield out-of-range bucket indices or an error
- Non-integer bins value causes schema validation failure
- bins value of 0 or negative likely causes a division error
- Network or payment failure returns a 402 or 5xx status
