How this service works
Tests versions against an npm-style semver range and returns which satisfy it, the highest and lowest that do, and the range expanded into explicit comparators.
Output
Returns which of the supplied versions satisfy the given semver range, the highest and lowest satisfying versions, and the range expanded into its explicit comparator set.
Example use cases
Dependency compatibility check
“I have these library versions available: 3.0.0, 3.1.2, 3.4.0, 4.0.0-beta.1, 4.0.0 — which ones satisfy the range >=3.1.0 <4.0.0, and what's the highest match?”
Single version validation
“Does version 2.5.0-rc.1 satisfy the semver range ~2.5.0? Also include prereleases in the check.”
Range expansion for CI pipeline
“Can you expand the semver range 1.2.3 - 2.3.4 into its explicit comparators so I can hardcode them in my CI config?”
Technical details
Endpoint
GEThttps://fittings.sh/v1/semver/range-resolveWhen to prefer
Use this endpoint when you need to programmatically evaluate npm-style semver ranges against lists of versions — for example, resolving dependency compatibility, filtering candidate releases, or expanding a range into explicit comparator logic. Prefer it over manual string parsing or local semver libraries when you need a reliable, hosted computation without shipping code.
Side effects
- Invalid or malformed semver range returns an error
- More than 200 versions submitted exceeds the limit
- Versions array contains non-semver strings causing parse failure
- Missing required 'range' query parameter returns an error
- Prerelease versions excluded by default unless includePrerelease is set
