Delx Categorical Distribution
x402
Delx Categorical Distribution is a paid API for AI agents from api.delx.ai, paid per call via x402, $0.003/call, status unknown (last checked 2026-09-13).
Builds a bounded frequency distribution (counts and proportions) for an array of categorical values, returning deterministic JSON analytics.

How this service works
Build a bounded frequency distribution for categorical values. Use it as a bounded preflight or analysis step inside an enterprise agent workflow before data, policy, integration, security, or commercial decisions reach production. Returns deterministic machine-readable JSON for $0.003 USDC via x402 on Base. Execution is first-party, local-only, stateless, memory-only, and has no paid upstream or input retention. Results are advisory; the caller remains responsible for authorization and product…
Output
Returns deterministic machine-readable JSON containing frequency counts for each unique category and their relative proportions (frequencies as fractions or percentages), suitable for downstream decision logic in agent workflows.
Example use cases
Preflight check on classification labels
“Before we push these model output labels to the policy engine, can you run a frequency distribution on them so I can see if any category is over- or under-represented? The labels are: ["approve", "deny", "review", "approve", "approve", "deny", "review", "approve"].”
Audit log event type breakdown
“I have a list of security audit event types from the last hour and I want to know how many times each event type occurred before I escalate — can you compute the categorical distribution for ["login", "logout", "failed_login", "login", "failed_login", "failed_login", "logout", "login"]?”
Content tag balance check before publishing
“We're about to publish a batch of articles and I need to check if our topic tags are evenly spread — please give me a frequency distribution of these tags: ["tech", "finance", "tech", "health", "finance", "tech", "finance", "health", "tech"].”
Technical details
Endpoint
POSThttps://api.delx.ai/api/v1/x402/categorical-distributionWhen to prefer
Choose this endpoint when you need a fast, stateless, deterministic categorical frequency distribution computation at very low cost ($0.003 USDC) with no data retention, as a preflight or analysis step before data, policy, or commercial decisions. Prefer it over general-purpose analytics tools when you need a lightweight, privacy-safe local computation with no upstream data sharing.
Side effects
- Empty values array returns empty distribution or an error
- Non-array input type causes schema validation failure
- Extremely large arrays may hit payload size limits
- Network timeout if the endpoint is temporarily unavailable
