Swift Bot Labs Toolbox – Semver Parser & Range Checker
x402
Swift Bot Labs Toolbox – Semver Parser & Range Checker is a paid API for AI agents from x402-toolbox.swiftbotlab.workers.dev, paid per call via x402, $0.003/call, status unknown (last checked 2026-10-31).
Parses, sorts, and validates semantic version strings, and checks which versions satisfy an npm-style range expression

How this service works
62 small, deterministic utility APIs (DNS and e-mail checks, web extraction, EVM decoding, x402 checks, IP math, JSON/CSV, hashing, conversions). No account or API key: pay per call in USDC with x402.
Output
Returns a JSON object with the tool name, the interpreted range, a sorted list of all input versions, a list of invalid (non-semver) strings, the subset of versions satisfying the range, and the single highest satisfying version (maxSatisfying).
Example use cases
Dependency compatibility check
“I have a list of available library versions: 1.0.0, 1.3.2, 2.0.0, 2.1.5, 3.0.0-beta.1 — which of them satisfy the range >=2.0.0 <3.0.0, and what's the max satisfying one?”
Release list validation and sort
“Can you sort these version strings and flag any that aren't valid semver: 1.0.0, v2.3, 0.9.1, 2.0.0-alpha.1, not-a-version, 1.10.5?”
CI pipeline version resolution
“My CI pipeline has these candidate versions: 3.1.0, 3.2.4, 3.2.10, 4.0.0 — which is the highest one that satisfies ~3.2.0?”
Technical details
Endpoint
GEThttps://x402-toolbox.swiftbotlab.workers.dev/v1/semver?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need deterministic, server-side semver parsing and range resolution without installing a local library — especially useful in agent pipelines that work with package manifests, release lists, or CI/CD version gating. Ideal for stateless, one-off semver queries that need no account setup, paying per call in USDC.
Side effects
- Missing required 'versions' query parameter returns an error
- Malformed version strings are returned in the 'invalid' array rather than causing a failure
- Invalid or unparseable range expression may result in an empty satisfying list or error
- Payment failure (x402 protocol) blocks the request if USDC payment is not completed
