x402
Delx Commerce X402 Delivery Latency Check is a paid API for AI agents from commerce.delx.ai, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-01).
Checks whether a given API response latency falls within a specified maximum SLA threshold and returns a verifiable pass/fail result

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 original latency_ms and maximum_ms values, a boolean within_sla field, an overall status string ('pass' or 'fail'), an evidence block containing a SHA-256 hash of the inputs, confirmation that no data was retained, and the count of external calls made (always 0), enabling verifiable, auditable SLA checks.
Example use cases
Agent SLA compliance verification
“I just measured my API response at 350ms and my SLA cap is 500ms — can you verify whether that's within the allowed threshold and give me proof it passed?”
Latency budget gate before payment release
“Before I release payment for this delivery, confirm that the observed latency of 800ms is within my maximum allowed latency of 1000ms and return a verifiable result.”
Real-time SLA breach detection
“My monitoring tool clocked a response at 1200ms against a 900ms max — tell me whether that breaches SLA so I can flag it immediately.”

Endpoint
POSThttps://commerce.delx.ai/api/v1/x402/x402-delivery-latency-check?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a cryptographically verifiable, pay-per-result SLA check with no signup and a tamper-evident SHA-256 input hash — ideal for autonomous agents operating under x402 payment protocols that need auditable proof of latency compliance without storing sensitive data.
Side effects
- Missing required fields (latency_ms or maximum_ms) returns a validation error
- Non-integer values for latency_ms or maximum_ms cause schema rejection
- Payment failure via x402 protocol blocks request processing
- Negative latency values may produce undefined behavior
