Canto API

Canto's API reaches a company's assets in its DAM with OAuth from the DAM Plus plan up, and webhooks report changes. Style guides stay in the app, no MCP yet.

Last updated 2026-11-10

Canto is a digital asset management (DAM) system. Its API, on the company's own Canto domain with OAuth 2.0, finds and downloads assets as originals or previews, and webhooks tell other systems when assets are uploaded, changed or deleted. Canto's Style Guides present a brand's colours, typography and imagery, but inside the app; the API has no endpoint for them.

It suits products that sync approved files from a customer's Canto library.

  • Logos Partly
  • Colours No
  • Fonts No
  • Guidance No
  • Files Yes

What does Canto return?

  • LogosNo logo-specific type; logos are assets like any other file, identified by content ID and scheme.
  • ColoursNo endpoint for brand colours; the API covers content, folders, albums, uploads, downloads, reports and settings.
  • FontsNo endpoint for fonts or typography.
  • GuidanceNo endpoint for style guides or brand guidelines; Canto's Style Guides are built and viewed in the app.
  • FilesAssets can be downloaded as the original file, a preview at a chosen size, high or low JPG, or PNG.

How is it billed?

Pricing scales with team size and storage, with capabilities chosen per plan.

What are the limits?

Each call has a rate level: for customers, level 1 allows 1,000 calls a minute down to 50 a minute at level 5; trial accounts have lower levels; above the limit the API returns 429.

What do the terms require?

CloudFront (CDN) URLs expire and keep delivering the old version after an asset changes; Direct URLs stay the same and redirect to the current file.

Who keeps it current?

The customer's team, which manages assets in Canto; webhooks notify other systems when assets are uploaded, changed or deleted so they stay in sync.

How do you call it?

GET {{SITE_BASEURL}}/api_binary/v1/:scheme/:contentId

What should you watch for?

  • Plan. API and MCP access are listed from the DAM Plus plan up; DAM Essentials doesn't list them.
  • Links that go stale. CloudFront URLs expire and keep serving the old version after an asset changes. Direct URLs stay the same and redirect to the current file.
  • MCP. Canto's MCP server today works on Product Hub product records, not the DAM library. An MCP server for the DAM is listed as coming soon.
