Verified by agenttru.st

Everything here is a check agenttru.st performed itself. Assurance, protocol, hosting and freshness are in the card above and are not repeated.

Certificate: Issued by Let's Encrypt domain-validated
Valid until 12 Jan 2027 as of our check on 10 Nov 2026. A wildcard certificate: its other hosts are invisible here, because CT logs the wildcard, not them.

Control of the hostname was checked; nothing about who operates it.

Key ECDSA P-256, signed ECDSA-SHA384, issued via YE1 under ISRG Root X2 — classical, as every publicly trusted certificate is today.

What this agent says it can do

Declared in the agent's own card. agenttru.st has not tested whether it completes any of these tasks — the operator of byondr.co controls every word below.

Image Tools: process_images

Resize, crop, rotate, flip, compress (to a file size with target_bytes), convert (jpeg, png, webp, avif), strip EXIF and GPS metadata from, and watermark (text, logo or both) one image or a zip of up to 50 images (up to 500 files per zip; files that are not supported images are skipped and listed). Crops are in pixels by default; for a zip of different sizes use crop_unit "percent" or crop_aspect, which are worked out per image. Give exactly one source: file_id (from create_upload), url (public https) or data_base64 (up to 3 MB inline; use create_upload, up to 100 MB, or url above that). One image in returns one image; a zip returns a zip. AVIF output is scaled down to fit 1,200 px on the longest side and WebP output to 36 megapixels. Returns a 24-hour download_url with the size and format of every output, and for each output the kinds of metadata found in the input and left in the output (location, date, camera, serial number, ...) and whether the colour profile was kept; kinds only, never the values. keep_d

Image Tools: create_upload

Get a one-hour signed upload URL for an image or a zip that is too large to send inline (over 3 MB; up to 100 MB here) or that already sits on disk. PUT the raw bytes to upload_url with a Content-Length header, then pass file_id to process_images. Free.

Receipts & invoices to spreadsheet: extract_documents

Read receipts and invoices (JPG, PNG, WebP, HEIC, PDF, or a zip of them; one document per file or PDF; up to 25 documents per call, 10 MB each, PDFs up to 10 pages) into checked numbers. Give each file as file_id (from create_upload), url (public https) or data_base64 (up to 2 MB inline). MCP requests are capped near 4 MB by the SDK, so keep all inline base64 in one call under about 2 MB and use create_upload for more. Returns one entry per document with vendor, date, currency, line items, subtotal, tax, total and payment method, each field marked ok, check or missing, the checks that ran, a status of ready or needs_review with review_reasons, and duplicate_of for a repeated receipt. Money is a decimal string, never a float. Each document also carries printed: its dates and currency as printed, the paths of fields whose text could not be read (printed.unreadable), the paths of fields a second read changed after a failed check (printed.second_look), and the paths of amounts printed with a dotted thousands sepa

Receipt Maker: list_templates

List the receipt templates make_receipt can use, each with its slug, name, category and kind (brand or generic). Filter by category, kind or a query on the name or slug.

Receipt Maker: make_receipt

Make a receipt file from a template, with your own items, and get a 24-hour download link. Call list_templates for a slug first.

Every other field you leave out (store name and address, date, currency, tax, payment, discounts, extra_lines, messages, barcode) uses the template's sample value, so pass an empty array to clear discounts, extra_lines or messages. format is png (default), jpeg or pdf. An optional logo goes on top: PNG, JPEG or SVG up to 2 MB (a PNG or JPEG at most 2 megapixels, for example 1600×1250; resize a bigger one first), as file_id (from create_upload), url or data_base64; it replaces the template's logo, and header.logo "none" removes the template's logo. Returns url, expires_at, the delivered image size in pixels (for a PDF, the page at 1x), the totals as formatted strings, and notes for anything that was left out o
