Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 ucf-v2-identity-compiler-30800ccd -d '<json body>'
```

Example prompt: Compile a system prompt for an AI persona named 'Aria' with axioms like 'always be concise' and 'cite sources', a warm and professional voice, never discussing politics or competitors, operated by 'Acme Corp' in the role of 'customer support assistant'.

## When to prefer this

Choose this endpoint when you need to programmatically generate a structured, deployable system prompt from a well-defined persona specification and operator context — especially when building multi-agent pipelines, SaaS products with configurable AI personas, or platforms that need dynamic system prompt generation at runtime. Prefer this over hand-writing system prompts when persona attributes (axioms, voice, constraints) are data-driven or user-configurable.

## Known failure modes

- Missing required persona fields (name, axioms, voice, never) returns a validation error
- Fewer than 2 or more than 4 axioms causes schema rejection
- Missing operator name or role returns a 400-level error
- Payment failure via x402 protocol blocks the request
- Malformed body type or method mismatch returns an input error
- Cloudflare tunnel downtime may cause 502 or timeout errors

## How this service works

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

## Output

Returns a compiled system prompt object derived from the provided persona pack, operator context, and optional session metadata — ready to be injected as the system message for an AI model deployment.
