# Delx Commerce — Agent Delivery SLA Check

> Delx Commerce — Agent Delivery SLA 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).

Validates whether an agent task delivery meets SLA requirements by checking success, completion, and latency against a maximum threshold.

## Facts

- Endpoint: POST https://commerce.delx.ai/api/v1/x402/agent-delivery-sla-check?utm_source=zero.xyz
- Price: $0.001/call
- Payment: x402
- Status: unknown
- Last checked: 2026-10-01
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/delx-commerce-agent-delivery-sla-check-afe1b07f
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_Lk9YGe8CEZYbjSj7uSTSz

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability delx-commerce-agent-delivery-sla-check-afe1b07f -d '<json body>'
```

Example prompt: Check if my last agent task delivery passed SLA — it succeeded, it completed, it took 320 milliseconds, and the maximum allowed latency is 500 milliseconds.

## When to prefer this

Choose this endpoint when you need a lightweight, auditable, cryptographically-evidenced SLA compliance check for an agent task delivery without storing any input data. It is ideal when you need a verifiable on-chain-payable micro-check (0.001 USDC) that produces a tamper-evident SHA256 evidence hash confirming inputs were not retained, making it suitable for delivery contracts between autonomous agents.

## Known failure modes

- Missing required fields (success, complete, latency_ms, maximum_latency_ms) may result in a validation error
- Non-integer latency values may cause a schema rejection
- Payment failure via x402 protocol will block the call before processing
- If maximum_latency_ms is zero or negative the result may be undefined

## 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 a result block containing success, accepted, complete, and latency_within_sla booleans; a top-level status field ('pass' or 'fail'); and an evidence block with a SHA256 hash of the input, a retained=false flag confirming no data is stored, and a count of external calls made (always 0), plus the operation name for auditability.
