How this service works
Compute cost per successful delivery from total cost and success count — call when dividing total cost by successful deliveries. 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…
Output
A deterministic JSON object containing the computed cost-per-success value, derived by dividing total_cost by success_count. The response is machine-readable and stateless, with no upstream data fetched.
Example use cases
Weekly SRE cost efficiency review
“Our total infrastructure cost this sprint was $12,500 and we had 3,200 successful deliveries. What was our cost per successful delivery?”
Incident post-mortem unit cost
“During last night's incident we spent $870 total and only 290 requests succeeded. Can you calculate our cost per success during that window?”
Comparing two deployment strategies
“Deployment A cost $5,000 with 2,500 successes, and deployment B cost $6,000 with 3,500 successes. Calculate the cost per success for both so I can compare efficiency.”
Technical details
Endpoint
POSThttps://api.delx.ai/api/v1/x402/cost-per-success?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a simple, deterministic, serverless computation of cost-per-success from raw totals — especially in SRE, ops, or delivery pipeline contexts where you want a zero-dependency, stateless calculation without maintaining your own math logic. Prefer it over general-purpose code execution when you want a reliable, auditable, cheap API call that returns structured JSON directly consumable by downstream agents.
Side effects
- Division by zero if success_count is 0 or missing
- Missing required fields (total_cost or success_count) result in validation error
- Non-numeric inputs cause schema rejection
- Negative values may produce nonsensical results if not validated by caller
