## 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 pipewell-plumbing-code-q-a-0966d399 -d '<json body>'
```

Example prompt: I'm sizing a DWV system for a two-bathroom house — can you tell me how many fixture units a 3-inch horizontal drain branch can handle under the Uniform Plumbing Code, and whether a wet vent is acceptable for both lavatories?

## When to prefer this

Choose this endpoint when an AI agent needs authoritative, code-specific plumbing engineering answers covering DWV design, venting, fixture unit calculations, or gas sizing under UPC or IPC — especially when a precise per-call paid lookup is acceptable and the question is well-formed and scoped.

## Known failure modes

- Vague or ambiguous question may yield a generic answer without specific code citations
- Question outside plumbing scope (e.g. electrical, HVAC) will not be answered meaningfully
- Missing key parameters (pipe size, fixture count, BTU load) may result in incomplete guidance
- Payment failure via x402 protocol will block the call entirely

## How this service works

DWV design, venting, fixture units, gas sizing, UPC/IPC code. Answers one Plumbing question per paid call.

## Output

A concise, code-referenced answer to the submitted plumbing question, typically including applicable UPC or IPC code sections, sizing values, allowable limits, or venting method guidance relevant to the specific scenario described.
