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).

Example use cases

Extract filename from download response

“I got this Content-Disposition header back from a file download: 'attachment; filename="invoice_2024.pdf"' — can you parse it and tell me the filename and disposition type?”

Validate inline vs attachment disposition

“Check this Content-Disposition header and tell me whether the content is meant to be displayed inline or downloaded as an attachment: 'inline; filename="preview.html"'.”

Automate file naming in download pipeline

“My pipeline received this header from an API response: 'attachment; filename="data_export_march.csv"; filename*=UTF-8''data_export_march.csv' — parse it out so I know what to name the saved file.”

When to prefer

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).

Side effects

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
