Delx P95 Estimate
x402
Delx P95 Estimate 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).
Estimates the 95th percentile (p95) latency from a bounded numeric sample array, returning a deterministic JSON result.

How this service works
Estimate p95 latency from a bounded numeric sample — call when estimating p95 from a bounded numeric sample. Use for SRE/ops math agents buy from broad utility catalogs: SLA, error budget, success rate, and health scores with zero upstream cost. Returns deterministic machine-readable JSON for $0.003 USDC via x402 on Base. Execution is first-party, local-only, stateless, and memory-only with no paid upstream, no input retention, and no claim of live chain tip, web search, or media generation. Re…
Output
Returns a deterministic JSON object containing the estimated p95 (95th percentile) value derived from the provided numeric sample array. The response is machine-readable and stateless, with no upstream dependencies.
Example use cases
SLA compliance check for API service
“I have these latency samples from our payment API over the last hour: [45, 67, 123, 89, 204, 56, 310, 78, 95, 112, 88, 143]. Can you estimate the p95 latency so I can check if we're within our 200ms SLA?”
Error budget burn rate assessment
“We have a 99.5% SLA and I want to understand our tail latency exposure. Here are 20 response time readings in ms: [50, 60, 55, 70, 300, 58, 62, 480, 53, 61, 59, 57, 66, 72, 55, 63, 68, 51, 74, 290]. What's the p95 estimate?”
On-call triage during incident
“Our alerting fired on elevated latency. I've got these sampled response times from the last 5 minutes: [90, 102, 98, 115, 870, 105, 99, 95, 1100, 108, 97, 103, 960, 112, 101]. Can you quickly compute the p95 so I know how bad the tail is?”
Technical details
Endpoint
POSThttps://api.delx.ai/api/v1/x402/p95-estimateWhen to prefer
Choose this endpoint when you need a fast, cheap, deterministic p95 latency estimate from a sample array with no external dependencies. Ideal for SRE agents, ops dashboards, and SLA-checking pipelines that need tail latency quantification at scale without paying for heavyweight analytics infrastructure. At $0.003 per call it is cost-effective for high-frequency monitoring loops. Prefer this over general-purpose statistics libraries when you want a zero-setup, stateless HTTP computation with a consistent JSON response contract.
Side effects
- Empty or missing samples array — likely returns an error or null result
- Non-numeric values in the samples array — may cause computation failure or be silently ignored
- Insufficient sample size — may produce statistically unreliable p95 estimate
- Payment failure via x402 — request blocked if $0.003 USDC transaction cannot be completed
- Malformed JSON input — 400-level error returned
