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 containing the schema identifier ('delx/util-cost-per-success/v1'), the original total_cost, the original success_count, and the computed cost_per_success as a decimal number (e.g. 0.25 for $0.25 per success).
Example use cases
Agent fleet unit economics check
“My agent fleet completed 200 successful tasks this hour and the total cost was $48.00 — what was my cost per success?”
Campaign cost efficiency reporting
“We ran a pay-per-result campaign: 75 successful deliveries, $18.75 total spend. Can you tell me the cost per successful outcome?”
Budget optimization across runs
“Over the last window I spent $5.00 and got 25 successful results — compute my cost per success so I can benchmark against my $0.18 target.”
Technical details
Endpoint
POSThttps://commerce.delx.ai/api/v1/x402/cost-per-success?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a quick, on-demand computation of cost-per-success unit economics without building your own division logic, especially within a pay-per-result agent workflow on Delx Commerce that already uses USDC micropayments via x402. It is ideal for lightweight, real-time cost reporting inside agentic loops where you want a schema-versioned, verifiable response rather than doing the arithmetic inline.
Side effects
- Missing or zero success_count causes division-by-zero or validation error
- Non-numeric values for total_cost or success_count cause a 400 bad request
- Negative values for either field may produce unexpected or invalid results
- Payment not provided or insufficient USDC triggers an x402 payment-required response
