Delx Arithmetic Mean
x402
Delx Arithmetic Mean is a paid API for AI agents from api.delx.ai, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-13).
Computes the arithmetic mean of a numeric array and returns the result as JSON, billed per call via x402.

How this service works
Arithmetic mean of numbers. Call when summarizing metrics, scores, or sensor lists mid-pipeline. Returns the mean of a numeric array as JSON. $0.001 USDC per successful call via x402 on Base—deterministic first-party JSON, no API key, no subscription, and nothing is billed on structured validation errors.
Output
A JSON object containing the arithmetic mean of the submitted numeric array, computed server-side and returned as a first-party deterministic result. No rounding surprises or external dependencies — just the calculated mean value.
Example use cases
Averaging sensor readings in IoT pipeline
“I've got a batch of temperature sensor readings — 22.1, 23.4, 21.8, 24.0, 22.9 — can you compute the average so I can use it as the normalized value for this time window?”
Summarizing test scores for reporting
“Average these student test scores for me: 88, 92, 75, 84, 91, 78, 95, 63 — I need the mean to include in the class summary report.”
Aggregating API latency metrics mid-pipeline
“Take these API response times in milliseconds — 120, 145, 98, 210, 133, 175 — and compute the mean so I can compare against our SLA threshold.”
Technical details
Endpoint
POSThttps://api.delx.ai/api/v1/x402/meanWhen to prefer
Use this endpoint when you need a fast, deterministic, no-subscription mean calculation inside an agent pipeline — especially when you already pay per call via x402 and want consistent JSON output without managing a math library or an external analytics service. Ideal for mid-pipeline metric normalization, sensor aggregation, or score summarization where simplicity and auditability matter.
Side effects
- Empty array (minItems:1 violated) returns a structured validation error with no charge
- Array exceeding 10,000 items (maxItems:10000) returns a validation error with no charge
- Non-numeric values in the array trigger a schema validation error
- Network timeout or service unavailability results in a failed request; payment only applies on success
