Purpose & Capability

Name/description and declared requirements match: the skill calls a hosted OCR API (pdfapihub.com) and requires PDFAPIHUB_API_KEY. There are no unrelated env vars or binaries requested.

✓

Instruction Scope

SKILL.md explicitly instructs uploading images (image_url, base64_image, or multipart file) to https://pdfapihub.com/api and sending the API key in the CLIENT-API-KEY header. It does not instruct reading unrelated files, environment variables, or system state. It also contains a privacy warning about uploads.

✓

Install Mechanism

No install spec or code files; instruction-only skill. No downloads or archive extraction are performed by the skill itself.

✓

Credentials

Only a single API key (PDFAPIHUB_API_KEY) is required, which is proportional to contacting the external OCR service. The primaryEnv matches the header name documented in SKILL.md/skill.json.

✓

Persistence & Privilege

always is false and the skill is user-invocable. It does not request persistent or cross-skill configuration changes and does not demand elevated platform privileges.

Assessment

This skill is coherent but remember it sends your images and the extracted text to a third party (pdfapihub.com). Do not upload sensitive images (IDs, passports, medical records, passwords) unless you trust the provider and their retention policy (the SKILL.md claims files are auto-deleted after 30 days). Before installing or using: verify the service domain and privacy/terms pages, use a dedicated API key with limited scope if possible, monitor for unexpected billing, rotate the key if it is ever exposed, and consider local/offline OCR if you need stronger privacy guarantees.

Like a lobster shell, security has layers — review code before you run it.

Image OCR Parse

What It Does

Extracts text from images via the PDFAPIHub hosted OCR API. Your image is uploaded to PDFAPIHub servers where Tesseract OCR processes it and returns the extracted text. Supports optional image preprocessing to improve OCR quality on low-resolution or noisy inputs.

When to Use

Extract text from photos of receipts, signs, or documents
OCR business cards, ID cards, or labels
Process low-quality images with preprocessing

Required Inputs

Provide one of:

image_url — URL to an image
base64_image — base64-encoded image
Multipart upload with file field

Authentication

This skill calls the PDFAPIHub hosted API at https://pdfapihub.com/api. Your image is uploaded to PDFAPIHub servers for OCR processing.

Send your API key in the CLIENT-API-KEY header.

Get your free API key at https://pdfapihub.com. Full API documentation is available at https://pdfapihub.com/docs.

Privacy note: Images you process are uploaded to PDFAPIHub's cloud service and the extracted text is returned. Do not send sensitive images unless you trust the service. Files are auto-deleted after 30 days.

Use Cases

Receipt Scanning — Extract text from receipt photos for expense tracking
Business Card Reader — OCR business card images to extract name, phone, email
License Plate Recognition — Extract plate numbers from photos (with char_whitelist)
Meter Reading — Extract digits from utility meter photos for automated logging
Whiteboard Capture — OCR whiteboard or handwritten note photos into text
Product Label Scanning — Extract ingredient lists or nutrition info from product label photos

Image Preprocessing Options

Param	Default	Description
`grayscale`	false	Convert to grayscale
`sharpen`	false	Apply sharpening
`threshold`	0	Binarization threshold (1–255)
`resize`	0	Scale factor (max 4x)
