Delx Commerce Latency Summary API
x402
Delx Commerce Latency Summary API is a paid API for AI agents from commerce.delx.ai, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-01).
Computes descriptive latency statistics (min, max, mean, p50, p95, p99) from an array of millisecond latency values

How this service works
Pay-per-result APIs for agents. No signup. Exact price. Verifiable delivery. USDC on Base + Solana via x402.
Output
A JSON object containing the count of samples, minimum, maximum, mean, p50, p95, and p99 latency values in milliseconds, plus a schema version identifier ('delx/latency-summary/v1').
Example use cases
API performance regression check
“Here are the response times in milliseconds from our last load test: [10, 15, 22, 45, 120, 300, 18, 25]. Can you compute p50, p95, and p99 latency so I can see if we have a regression?”
SLA compliance verification
“I have 500 latency samples from our payment service over the last hour — compute the full latency summary including min, max, mean, p50, p95, and p99 so I can check if we're within our 200ms p95 SLA.”
Comparing two deployment latencies
“I collected these response times from our new deployment: [8, 12, 11, 9, 35, 14, 10]. Can you summarize the latency stats so I can compare against last week's numbers?”
Technical details
Endpoint
POSThttps://commerce.delx.ai/api/v1/x402/latency-summary?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a quick, pay-per-call latency statistics summary without setting up any analytics infrastructure or accounts. It is ideal for agents that periodically collect timing data and need computed percentiles on demand, especially in cost-sensitive or serverless contexts where a $0.002 per-call model is preferable to a subscription-based observability platform.
Side effects
- Empty array input returns a validation error (minItems: 1)
- Array exceeding 10,000 items is rejected (maxItems: 10000)
- Non-numeric values in the array cause a schema validation failure
- Payment failure or insufficient USDC balance on Base/Solana returns a 402 response
- Network timeout if the request takes too long to process
