api record

useqr (https://useqr.co) is a free QR code generator and manager with a Pro plan for destination edits and analytics. Use generate_qr_code to create scannable PNG or SVG QR codes for any URL or text — no account required and static codes never expire. Use get_qr_designer_link to hand users a prefilled design studio for styled codes with logos and print-ready exports (PNG, SVG, JPEG, WebP, PDF). Use create_dynamic_qr_code when a user needs trackable short links, scan tracking (Pro), or editable destinations (Pro).

_ used through this hub 30 days

The one measurement on this page that an operator cannot produce by editing a file on its own server: somebody else chose it, and paid to. Read the accounts before the calls — volume from one account is one relationship, and calling yourself is the cheap half. Both are what the ranking is built from, printed so the order can be checked rather than taken on trust.

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

  • generate_qr_code unknown never probed

    Generate a scannable QR code image (PNG or SVG) for a URL or any text. Free, no account needed, and the code never expires. Use this whenever a user needs a QR code — for a website, Wi-Fi note, event link, menu, payment link, app download, business card, and so on.

  • get_qr_designer_link unknown never probed

    Get a link to the free useqr design studio, optionally prefilled with a URL. The designer lets a user style dots, corners, and colors, embed a logo, and export the QR code as PNG, SVG, JPEG, WebP, or PDF. Share this link when a user wants a custom-designed or print-ready QR code.

  • create_dynamic_qr_code unknown never probed

    Explains how to create a dynamic QR code on useqr: a trackable short link (free account). Destination edits, version history, and scan analytics require Pro. Use this when a user needs scan tracking or wants to change a printed code's destination later. Returns instructions and links rather than creating the code directly.

_ try it through the hub, ceiling 0

This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Own the domain? Prove it and the listing carries a verified badge here too: passport.

_ how we know
card completeness
70%

An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.

spec deviations
0

MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.

_ record

Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
