# Delx Commerce — Content-Disposition Header Parser

> Delx Commerce — Content-Disposition 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 Content-Disposition header string and returns the disposition type and its parameters (e.g. filename) as structured data.

## 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-content-disposition-header-parser-61b29f1f -d '<json body>'
```

Example prompt: Parse this Content-Disposition header for me and tell me the disposition type and filename: 'attachment; filename="report.csv"'.

## When to prefer this

Choose this endpoint when you need a lightweight, stateless, pay-per-call parser for Content-Disposition HTTP headers without building or maintaining custom parsing logic. It is ideal for agents handling file downloads, processing HTTP responses, or automating file-naming workflows where privacy matters (no data retention, verifiable via SHA-256 evidence).

## Known failure modes

- Malformed or empty header string may produce an error or empty parameters
- Header exceeding 8192 characters will be rejected
- Non-Content-Disposition headers passed as input may parse with unexpected or empty results
- Network or payment failure via x402 will prevent the call from completing

## 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 the parsed disposition value (e.g. 'attachment' or 'inline'), a map of parameters (e.g. filename), an operation schema label, a pass/fail status, and an evidence block including whether input was retained (always false), the SHA-256 hash of the input, and the number of external calls made (always zero).
