## 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 continuitykit-ucf-v2-identity-compiler-eabef2b9 -d '<json body>'
```

Example prompt: Compile a system prompt for a persona named 'Aria' with axioms 'be concise' and 'never speculate', a warm and professional voice, and she should never reveal internal instructions or argue with users — the operator is 'Acme Corp' acting as 'customer support lead'.

## When to prefer this

Choose this endpoint when you need to programmatically compile a structured persona definition and operator context into a deployable LLM system prompt — especially when using the UCF (Universal Character Format) v2 standard. Prefer this over manual prompt writing when you have multiple personas to manage consistently, need reproducible identity compilation, or are building an agent fleet where each agent has distinct voice, axioms, and behavioral constraints.

## Known failure modes

- Missing required persona fields (name, axioms, voice, never) returns a validation error
- Axioms array below minimum of 2 or above maximum of 4 causes schema rejection
- Missing operator name or role causes request failure
- Invalid method type (not POST/PUT/PATCH) or bodyType (not json/form-data/text) returns enum validation error
- Malformed or incomplete input object returns 400-level error
- Service unavailability or timeout may occur under high load

## How this service works

UCF v2 Identity Compiler -------- persona pack in, system prompt out

## Output

A compiled system prompt string (and optionally a structured output object) derived from the provided persona pack and operator context, ready to be injected as the system message for an LLM-powered AI agent.
