How this service works
File conversion: image resize/reformat, CSV→JSON, HTML→PDF, DOCX→PDF. Part of the Bismuth utility API suite for AI agents.
Output
Returns the converted file in the requested output format — a resized/reformatted image binary, a JSON object parsed from CSV, or a PDF document generated from HTML or DOCX input.
Example use cases
Spreadsheet data pipeline prep
“I have a CSV export from our database — can you convert it to JSON so our backend can ingest it directly?”
Printable report from web content
“Take this HTML report I've drafted and convert it into a PDF I can send to the client.”
E-commerce product image resizing
“Resize this product photo to 600x600 pixels and reformat it from PNG to JPEG so it loads faster on our store.”
Technical details
Endpoint
POSThttps://x402-conversion-api-production.up.railway.app/convertWhen to prefer
Choose this endpoint when you need lightweight, pay-per-call file conversion without managing your own conversion infrastructure — especially useful in agent pipelines that need to normalize data formats (CSV→JSON) or produce printable documents (HTML/DOCX→PDF) on the fly. At $0.02 per call it is cost-effective for low-to-medium volume automated workflows.
Side effects
- Unsupported input format returns an error indicating the format is not accepted
- Malformed or corrupt file may cause a processing error
- Image resize with invalid dimensions returns a validation error
- File size exceeding limits may be rejected
- Network timeout on large file uploads
