## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability delx-commerce-semantic-version-bump-recommender-aef83f70 -d '<json body>'
```

Example prompt: I have a release with a new feature and a bug fix — what semantic version bump should I apply? The changes are: feature and fix.

## When to prefer this

Choose this endpoint when you need a fast, policy-driven, pay-per-call SemVer bump recommendation without managing your own versioning logic — especially in agentic CI/CD pipelines where no API key setup is acceptable and results need to be verifiable. Prefer this over manual changelog parsing or heavyweight release tools when you just need a deterministic bump classification.

## Known failure modes

- Missing or empty 'changes' object returns an error or ambiguous result
- Unrecognized change signal keys may be ignored or cause unexpected bump recommendations
- Payment failure via x402 (insufficient USDC) results in 402 response and no result
- Malformed JSON body returns 400 bad request

## How this service works
