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 resolved MIME type string (e.g. 'image/svg+xml') corresponding to the queried file type or content descriptor.
Example use cases
Content-type header for file uploads
“I'm building a file uploader and need to know the correct MIME type to use in the Content-Type header for .xlsx Excel files — can you look that up for me?”
Validate MIME type for API response
“What's the correct MIME type string for serving WebP images? I want to make sure I'm setting the right Content-Type header on my image API responses.”
Classify unknown file format
“I have a .tar.gz file and I need to know what MIME type to assign to it — can you look up the standard content-type for that format?”
Technical details
Endpoint
POSThttps://commerce.delx.ai/api/v1/x402/mime-lookup?utm_source=zero.xyzWhen to prefer
Use this endpoint when an agent needs a quick, authoritative MIME type lookup for a specific file extension or content descriptor without setting up a local lookup table, and when micropayment via USDC on Base or Solana is acceptable. Prefer this over hardcoded lookup tables when up-to-date or comprehensive coverage across many formats is needed.
Side effects
- Unknown or non-standard file extension returns empty or null MIME type
- Malformed request body causes 400-level error
- Payment failure (insufficient USDC balance) results in 402 Payment Required
- Unsupported bodyType enum value causes validation error
