# Scores Silktide 4 and Silktide 5 each give a website scores out of 100, but they work them out differently, so the same website gets different numbers from each. The API keeps them apart: each edition has its own scores operations, and each one names its edition. | | Silktide 4 | Silktide 5 | | --- | --- | --- | | Latest scores | [`/v1/results/scores`](https://developers.silktide.com/v1/governance/scores/get-scores.md) | [`/v1/results/module-scores`](https://developers.silktide.com/v1/governance/scores/get-module-scores.md) | | A score over time | [`/v1/results/score-trend`](https://developers.silktide.com/v1/governance/scores/get-score-trend.md) | [`/v1/results/module-score-trend`](https://developers.silktide.com/v1/governance/scores/get-module-score-trend.md) | | Score ids | Silktide 4's categories, such as `overall`, `content` and `wcag-22-aa`. Websites do not all have the same ones. | The four modules and WCAG at each version and level. Always the same 13. | ## Which to call Call the operations for the edition of Silktide your account uses. An account that has only one edition is refused the other's operations with an `EditionNotAvailable` error, which names the operation to call instead: ```json { "error": { "type": "EditionNotAvailable", "message": "This account does not have Silktide 4, so it cannot use /v1/results/scores. Use /v1/results/module-scores instead.", "properties": { "edition": 4, "instead": "/v1/results/module-scores" }, "status": 403 } } ``` Like other results errors, it comes back with status `200` and the error's own status inside it. See [Results](https://developers.silktide.com/v1/concepts/results.md). An account that has both editions can call both. If you are moving from Silktide 4 to Silktide 5, keep reading Silktide 4's scores until you have switched, and expect the numbers in your own reports to change on the day you do. ## How the ids match Where a Silktide 4 score has a Silktide 5 counterpart, it measures the same thing. The numbers still differ, because the two editions test and weigh pages differently. Do not join the two series into one line. | Silktide 4 id | Silktide 5 id | | --- | --- | | `content` | `content` | | `ux` | `user-experience` | | `wcag-20`, `wcag-21`, `wcag-22` | `accessibility` | | `wcag-20-a`, `wcag-20-aa`, `wcag-20-aaa` | the same ids | | `wcag-21-a`, `wcag-21-aa`, `wcag-21-aaa` | the same ids | | `wcag-22-a`, `wcag-22-aa`, `wcag-22-aaa` | the same ids | | None | `compliance` | | `overall`, `marketing` and the rest | None | Silktide 5 has no overall score. Each module stands on its own. Reports, report schedules and report templates are Silktide 4's too. An account with only Silktide 5 gets a `403` with an `EditionNotAvailable` error from them. Most other operations, such as websites, checks and content, work for both editions. Each operation's page says which editions it works for.
