  • Not measured
    Fast (p50)

    Median latency 494 ms over 1 samples in 7 days. The bar is 1000 ms. Need at least 5 samples.

  • Not measured
    Consistent (p95)

    95th percentile 494 ms over 1 samples in 7 days. The bar is 3000 ms. Need at least 20 samples.

  • Not measured

    1 of 1 attempts returned a tool list in 30 days (100%). The bar is 99%. Need at least 30 samples.

  • Not measured
    Stable tool list

    Fewer than two successful probes in 30 days, so tool-list stability is not measured.

Access

  • Pass
    Open access

    tools/list succeeded with no credential, and the record declares none.

  • Not measured
    Standard auth

    Auth is not required, so the OAuth metadata check does not apply.

Capabilities

Tools 10

barcode_size

Give the printed size of a barcode type at a GS1 magnification (retail and carton types) or an X-dimension, with the GS1 allowed range.

Discovered
calculate_check_digits

Add the GS1 check digit to GTIN numbers that are missing it (7, 11, 12 or 13 digits become GTIN-8, UPC-A, EAN-13 or GTIN-14). One number per line or comma separated.

Discovered
check_amazon_code

Read the code from an Amazon sticker: tells an LPN (License Plate Number) from an FNSKU, ASIN, FBA box label, Amazon Logistics tracking number or UPC/EAN, and explains each part. It cannot look up which product a code belongs to.

Discovered
convert_isbn

Convert an ISBN-10 to ISBN-13 or back, with the check digit recalculated and the hyphenated form. ISBN-13 starting with 979 has no ISBN-10.

Discovered
convert_upc_e

Convert a UPC-E (6, 7 or 8 digits) to the full 12-digit UPC-A, or a UPC-A to UPC-E when one of the four GS1 zero-suppression rules fits. Checks the check digit.

Discovered
identify_code

Find out what kind of code a string is: GTIN, ISBN, ISSN, SSCC, GLN, GS1-128 data, GS1 Digital Link, VIN, IMEI, ASIN, Amazon LPN or FNSKU, with its check digit status.

Discovered
make_barcode

Draw a print-ready barcode and return it as SVG (or EPS) in millimetres, plus a link that opens it in the generator. Types: upc-a, ean-13, ean-8, itf-14, code-128, code-39, code-93, interleaved-2-of-5, codabar, msi, pharmacode, data-matrix, pdf417, aztec. GS1 retail types use magnification 80 to 200 (percent).

Discovered
parse_gs1

Split GS1 data (GS1-128, GS1 DataMatrix, Digital Link) into its Application Identifiers, with the name of each AI and any format error.

Discovered
repair_gtin

Recover a GTIN with unreadable digits: mark each unknown digit with ? or * and get every number that passes the GS1 check digit.

Discovered
validate_gtins

Check complete GTIN, EAN, UPC and ITF-14 numbers: says for each one whether the check digit is right and which GTIN length it is.
