How this service works
Pay-per-result APIs for agents. No signup. Exact price. Verifiable delivery. USDC on Base + Solana via x402.
Output
Returns a JSON object with the schema version, the input SLO percent, the computed budget percent (1 - SLO), the window request count, and the derived number of allowed failures (floor of budget_percent * window_requests).
Example use cases
SRE error budget planning
“I'm running an SLO of 99.5% and I expect 200000 requests this month — how many failures can I tolerate before I breach my error budget?”
Reliability threshold validation
“Our system has a 99.99% SLO. If we get 1000000 requests this quarter, what's the exact number of allowed failures we have in our error budget?”
Incident impact assessment
“We had an outage and I need to know our remaining margin — we're at 99.9% SLO across a 50000 request window. What's the total allowed failure count?”
Technical details
Endpoint
POSThttps://commerce.delx.ai/api/v1/x402/error-budget-plan?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a quick, pay-per-result computation of SLO error budgets without setting up any infrastructure or subscribing to a service. Ideal for agents performing reliability calculations on demand, or for SRE workflows that need to programmatically derive allowed failure counts from SLO targets and request volumes.
Side effects
- Missing or invalid slo_percent causes computation failure or unexpected results
- slo_percent outside 0–100 range may yield nonsensical budget values
- Missing window_requests results in incomplete or errored response
- Payment failure via x402 protocol blocks request processing
