How this service works
Call when an agent needs semver tokens extracted from text, capped at 20 matches. An empty match list is billed. No network. Exact $0.003 USDC. Prefer unpaid POST /v1/sandbox/regex-semver first.
Output
A list of up to 20 semantic version strings (e.g. '1.2.3', '4.17.21', '0.9.12-beta.1') found in the input text. If no semver tokens are found, an empty list is returned — and the call is still billed at $0.003 USDC.
Example use cases
Changelog version audit
“I have a long changelog entry and I need to know every semver version number mentioned in it — can you extract them all? Here's the text: 'Released 2.1.0, deprecating 1.9.3 and removing support for anything below 1.8.0. Also bumped peer dep to react@18.0.0.'”
Dependency list version scan
“Scan this snippet from our package.json output and give me every version string you find: 'express@4.18.2, lodash@4.17.21, axios@1.3.4, typescript@5.0.4, jest@29.5.0.'”
Deployment log version extraction
“Pull all the semver versions out of this deployment log so I can check what was actually shipped: 'Deploying api-service:3.4.1, rolling back frontend:2.0.0 due to failure in 2.0.1, sidecar pinned at 0.9.12.'”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/regex-semver?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to extract semantic version strings from unstructured or semi-structured text and don't want to implement or maintain a regex parser yourself. Prefer the free POST /v1/sandbox/regex-semver endpoint for testing or low-stakes use. Choose this paid endpoint for production agent workflows where reliability and no local compute overhead matter. Not suitable for IP address extraction, date parsing, or other version-like patterns — use a domain-specific extractor for those.
Side effects
- Empty match list returned (and billed) when no semver tokens exist in input text
- Input text exceeds 100,000 character limit — request rejected
- Malformed or missing 'text' field causes validation error
- More than 20 matches in text — only first 20 returned, rest silently truncated
