Integrating a QR code generator is a commitment: your product will call it for years and every code it makes is printed somewhere. This comparison lists what to check in any QR code API, says what the main providers generally offer, and sets out exactly what AriaQR's REST API and MCP server do.
What to check in any QR code API
Authentication and rate limits. Whether codes are dynamic, and whether the destination can be changed by API call. Whether analytics are readable by API, not just in a dashboard. Bulk: how many codes per call or per minute. Image input: URL, upload or base64. Output: PNG at print resolution, ideally with a download URL that does not expire. And the one most providers leave out: whether the code is verified before it is returned to you.
What the main providers generally offer
QR TIGER, Scanova, Uniqode and Hovercode are generally known to offer REST APIs on paid tiers, with dynamic code creation, destination updates and some form of analytics or bulk endpoint. Details, limits and pricing vary and change; check each provider's documentation. Bitly's API covers short links, which its QR codes ride on. Free generators and design tools generally have no API.
What AriaQR's API does
The REST API is documented on the developers page. Send an image URL or base64 and a destination to create a code; by default it is activated on the plan immediately and you get back the verified 2048px master's download URL, the short link, and a stats URL. List the account's codes. Read a code's analytics: scans, unique visitors, device, in-app browsers, city-level location. Change a destination. Pass a team id to make the code in a shared workspace, with the activation drawn from the team owner's plan. Keys are created on the account page and prefixed so they are easy to spot in logs.
The MCP server at the same host exposes create_code, list_codes, get_code_stats and set_destination as tools, so an AI assistant or an agent workflow can make and manage codes without custom glue.
Every API call runs through the same engine and the same verification as the website. A code that fails verification is not returned. That is the difference between an API that generates and an API that ships.
Side by side
| AriaQR | Typical platform API | |
|---|---|---|
| Authentication | Bearer key, created on the account page | API key, check their docs |
| Create dynamic code | Yes, from image URL or base64 | Yes, generally |
| The code itself | The image is the code | Styled grid with a logo |
| Verified before return | Yes | Rarely advertised |
| Change destination by API | Yes | Generally yes |
| Analytics by API | Yes: scans, uniques, device, in-app, city | Varies |
| Teams | Yes, pass a team id | Varies by tier |
| Bulk | No per-call cap; the account page also takes 50 images at a time | Bulk endpoints on higher tiers, check their docs |
| AI agents | MCP server with four tools | Rare |
| Pricing model | Included in the quarter plan; enterprise terms for volume (see pricing) | Check their current pricing |
Integration patterns that work
Platforms issuing a code per merchant, per property or per attendee: call create with the customer's logo and their destination, store the code and the stats URL against the customer, and expose the download URL in your own interface. Marketing teams automating campaign codes: create one code per placement with UTM-tagged destinations, then read analytics by API into your reporting. Agent workflows: give the assistant the MCP server and let it create codes from a brief.
The honest recommendation
If you need a specific enterprise integration one of the broad platforms already ships, read their docs first. If you want an API that returns codes made from your customers' own artwork and never returns a code that fails, with analytics, teams and an MCP server included, AriaQR is built for exactly that. The plan includes the API; enterprise terms cover volume.
