  • code (required) — string — Barcode number: 8/12/13/14 digits or ISBN-10 (spaces and hyphens ignored), e.g. 3017620422003
  • lookup — boolean — Also fetch product / book data from open databases (false = validate and convert only)

  Hints: read-only yes · destructive not declared · idempotent not declared · open-world yes

• read_barcode read-only

  Read barcodes and QR codes from an image (URL or base64): QR, Micro QR, DataMatrix, Aztec, PDF417, MaxiCode, EAN-13/8, UPC-A/E, Code 128/39/93, Codabar, ITF and DataBar. Finds every code in the picture, even rotated, small or inverted (phone photos, receipts, labels, screenshots), and returns each one's text, format, position and meaning (URL, Wi-Fi network, vCard, e-mail, phone, location, crypto payment URI, product GTIN). No code found = not charged. Paid ($0.001, x402).

  Parameters:

  • formats — array — Only look for these formats (default: all)
  • image_url — string — Public URL of the image (PNG, JPEG, WebP, GIF, BMP, TIFF; max 8 MB). Use this or image_base64
  • max_results — integer — Maximum codes to return
  • image_base64 — string — The image as base64 (or a data: URI), max 8 MB. Use this or image_url

  Hints: read-only yes · destructive not declared · idempotent not declared · open-world yes

• search_specs read-only

  Full-text search over abstracts and full texts, with extracted technical specifications (values, ranges, tolerances, units). Numeric constraints like "50 Nm" are matched. Paid ($0.001, x402).

  Parameters:

  • query (required) — string — Words and optional numeric constraints, e.g. 'torque sensor 50 Nm'
  • limit — integer — Maximum number of results to return
  • topic — string — Topic slug from list_topics, e.g. laser-calibration
  • category — string — Result category: tech_specs (specification tables) or general
  • year_from — integer — Earliest publication year to include

  Hints: read-only yes · destructive not declared · idempotent not declared · open-world no

• query_specs read-only

  Structured specification table filtered by quantity (e.g. accuracy, wavelength, range), unit family, unit and value range, with source document and license. Paid ($0.001, x402).

  Parameters:

  • max — number — Maximum value, in the requested unit
  • min — number — Minimum value, in the requested unit
  • unit — string — Exact unit, e.g. nm, MPa, N·m
  • limit — integer — Maximum number of results to return
  • query — string — Optional words the source document must contain
  • family — string — Unit family: length, pressure, torque, force, temperature, frequency, power, voltage, current, mass, volume, time, percent
  • quantity — string — e.g. accuracy, resolution, range, wavelength, torque, temperature

  Hints: read-only yes · destructive not declared · idempotent not declared · open-world no
