How this service works
244 pay-per-call data APIs for AI agents: official statistics and economy (ECB, Fed, Eurostat, World Bank, SEC, BOE, INE), crypto prices and sentiment, Spanish public data, compliance (sanctions, VAT, IBAN, LEI), science, weather, web and developer tools and local AI text tools. Pay in USDC via x402.
Output
Returns a JSON object containing the barcode type, the SVG image as a base64 string, a ready-to-embed data URI (data:image/svg+xml;base64,...), the file size in bytes, the image format ('svg'), and the full normalized barcode code string.
Example use cases
Retail product label barcode
“Create a UPC-A barcode image for the product code '012345678905' — I need it as an SVG with the number visible so I can put it on a label.”
Book ISBN barcode for publishing
“Generate an ISBN-13 barcode for my book with code '9781234567897', SVG format, and include the visible text so it's ready for the back cover.”
Warehouse asset tracking label
“Make me a Code128 barcode for the internal tracking ID 'WH-LOC-20249871' so I can print it as an asset label for our warehouse shelving.”
Technical details
Endpoint
POSThttps://api.vextorium.com/v1/barcode-generate?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to programmatically generate barcode images server-side for retail, publishing, inventory, or logistics use cases, especially when you need SVG output with an embeddable data URI and support for multiple barcode standards (EAN, UPC, ISBN, Code128, Code39). Prefer this over client-side barcode libraries when the generation must happen in an agent pipeline without browser dependencies.
Side effects
- Invalid or malformed barcode code string for the selected type (e.g. wrong digit count for EAN-13)
- Unsupported barcode type string provided
- Missing required 'code' field in request body
- Network timeout or server error returning 5xx
- Payment failure if USDC balance insufficient (x402 payment required)
