Endpoint Badge

Using the endpoint badge, you can provide content for a badge through a JSON endpoint. The content can be prerendered, or generated on the fly. To strike a balance between responsiveness and bandwidth utilization on one hand, and freshness on the other, cache behavior is configurable, subject to the Shields minimum. The endpoint URL is provided to Shields through the query string. Shields fetches it and formats the badge.

The endpoint badge takes a single required query param: url, which is the URL to your JSON endpoint

Example JSON Endpoint Response

{ "schemaVersion": 1, "label": "hello", "message": "sweet world", "color": "orange" }

Example Shields Response

Schema

Property	Description
`schemaVersion`	Required. Always the number `1`.
`label`	Required. The left text, or the empty string to omit the left side of the badge. This can be overridden by the query string.
`message`	Required. Can't be empty. The right text.
`color`	Default: `lightgrey`. The right color. Supports the eight named colors above, as well as hex, rgb, rgba, hsl, hsla and css named colors. This can be overridden by the query string.
`labelColor`	Default: `grey`. The left color. This can be overridden by the query string.
`isError`	Default: `false`. `true` to treat this as an error badge. This prevents the user from overriding the color. In the future, it may affect cache behavior.
`namedLogo`	Default: none. One of the named logos supported by Shields or simple-icons. Can be overridden by the query string.
`logoSvg`	Default: none. An SVG string containing a custom logo.
`logoColor`	Default: none. Same meaning as the query string. Can be overridden by the query string. Only works for named logos and Shields logos. If you override the color of a multicolor Shield logo, the corresponding named logo will be used and colored.
`logoWidth`	Default: none. Same meaning as the query string. Can be overridden by the query string.
`logoPosition`	Default: none. Same meaning as the query string. Can be overridden by the query string.
`style`	Default: `flat`. The default template to use. Can be overridden by the query string.
