# Agent Delivery SLA Check

> Agent Delivery SLA Check is a paid API for AI agents from api.delx.ai, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-14).

Validates agent delivery quality by checking latency, success, and completeness against a caller-defined SLA contract, returning acceptance or rejection status with mismatch reasons.

## Facts

- Endpoint: POST https://api.delx.ai/api/v1/x402/agent-delivery-sla-check
- Price: $0.001/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-14

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 agent-delivery-sla-check-be53cb49 -d '<json body>'
```

Example prompt: Before I accept this agent delivery and pay for it, check the SLA: the task succeeded, the result is complete, and it took 1200 milliseconds — the maximum allowed latency is 2000 milliseconds. Give me an explicit accept or reject verdict with any mismatch reasons.

## When to prefer this

Use this endpoint when you need a deterministic, contract-aware accept/reject verdict for an agent delivery before committing to payment or downstream actions. It is especially suited for x402 payment gating workflows where you want normalized evidence and documented mismatch reasons rather than a simple boolean comparison. Prefer this over manual latency comparisons when you need versioned, auditable SLA compliance records for agent orchestration pipelines.

## Known failure modes

- Missing required fields (success, complete, latency_ms, or maximum_latency_ms) result in validation errors
- Non-integer value for latency_ms or maximum_latency_ms causes schema rejection
- Negative latency values may produce unexpected comparison results
- Payment failure via x402 for the $0.001 USDC call fee blocks execution

## How this service works

Agent Delivery Sla Check: Agent Delivery Sla Check checks latency, success, and result completeness against an SLA from bounded caller-supplied values without an external provider. Call Agent Delivery Sla Check before paying for or accepting an x402 or agent delivery assembled from caller-supplied challenge and result metadata. Returns contract-specific checks, normalized evidence, mismatch reasons, and an explicit acceptance or rejection status for Agent Delivery Sla Check as versioned determi…

## Output

Returns a versioned determination including contract-specific SLA check results (latency pass/fail, success check, completeness check), normalized evidence values, a list of mismatch reasons if any checks fail, and an explicit acceptance or rejection status for the delivery.
