# Delx Commerce — HTTP Status Retry Classifier

> Delx Commerce — HTTP Status Retry Classifier 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).

Classifies whether an HTTP request with a given method and status code is retryable, given a set of retry-eligible status codes

## Facts

- Endpoint: POST https://commerce.delx.ai/api/v1/x402/status-retry-classify?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-http-status-retry-classifier-5b9fbc70
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_bNkZfb5KxVLOZJIpJi7L2

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-http-status-retry-classifier-5b9fbc70 -d '<json body>'
```

Example prompt: For a GET request that returned a 503 status, and where my retry policy allows retrying on 429, 503, and 504, check whether this request is retryable.

## When to prefer this

Choose this endpoint when you need a stateless, verifiable, pay-per-use computation to determine HTTP retry eligibility without building or maintaining your own retry classification logic. Ideal for AI agents that need auditable, tamper-evident retry decisions with cryptographic evidence of non-retention, especially in regulated or multi-party workflows where proof of computation matters. Prefer this over rolling your own if you need the SHA-256 input hash for audit trails.

## Known failure modes

- Invalid or missing 'method' field returns a validation error
- Status code outside valid HTTP range may produce unexpected classification
- Empty retry_statuses array will always return retryable: false
- Malformed request body returns a 4xx client error
- Payment failure via x402 protocol blocks request execution

## 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 a 'retryable' boolean, the original method and status echoed back, a pass/fail status, an operation identifier ('web_reliability:status_retry_classify'), and cryptographic evidence including the SHA-256 hash of the input and a flag confirming no data was retained externally.
