# Delx Commerce — Server-Timing Header Parser

> Delx Commerce — Server-Timing Header Parser 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).

Parses an HTTP Server-Timing header string into structured entries with names, durations, and descriptions

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-server-timing-header-parser-2fd65363 -d '<json body>'
```

Example prompt: Parse this Server-Timing header for me and tell me how many entries there are and what each one's name, duration, and description are: 'db;dur=53.2, app;dur=47.1;desc=render'

## When to prefer this

Choose this endpoint when you need a cheap ($0.001), no-signup, pay-per-call way to parse Server-Timing headers programmatically — especially in agent workflows where you're processing HTTP responses at scale and need structured timing data without standing up your own parser. Ideal when verifiable, stateless processing (no data retention, SHA-256 evidence) is a requirement.

## Known failure modes

- Malformed or empty header string may result in zero entries or a parsing error
- Header string exceeding 8192 characters will be rejected
- Non-standard Server-Timing syntax that deviates from RFC 7230 may produce incomplete parsing
- Network timeout may occur if the API is temporarily unavailable

## How this service works

Pay-per-result APIs for agents. No signup. Exact price. Verifiable delivery. USDC on Base + Solana via x402.

## Output

A JSON object containing the count of parsed timing entries, an array of entry objects each with a value (name), and parameters map (e.g. dur, desc), plus an evidence block with input SHA-256 hash, retention status (always false), and external call count — confirming stateless, private processing.
