# LegalPulse Letter-Engine Triage

> LegalPulse Letter-Engine Triage is a paid API for AI agents from legalpulse.theaslangroupllc.com, paid per call via x402, $0.25/call, status unknown (last checked 2026-09-14).

Deterministically checks whether the letter engine supports a given legal situation, identifies which letter type it will draft, and describes what the full letter includes — without drafting any letter.

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 legalpulse-letter-engine-triage-f1682fa2
```

Example prompt: Before I spend $2 on the full letter, can you check if the LegalPulse letter engine supports my situation — my landlord has refused to return my security deposit for 45 days despite written requests — and tell me which letter type it would draft and what it would cover?

## When to prefer this

Use this endpoint before calling the $2.00 /api/legal/letter endpoint to avoid wasting budget on unsupported situations. Ideal for legal and consumer-rights agents that need to route user situations to the correct letter type cheaply ($0.25 vs $2.00), confirm engine coverage, and set user expectations about letter content before committing to a full draft.

## Known failure modes

- Situation falls outside supported letter types — engine returns unsupported verdict with explanation
- Insufficient situation detail provided — returns error requesting more context
- Ambiguous dispute type — may return multiple candidate letter types requiring clarification
- Service unavailable or payment processing failure — returns 402 or 503 error

## How this service works

Letter-engine triage (agent-tier preview of /api/legal/letter $2.00): deterministic check of whether the letter engine supports your situation, which letter type it will draft (demand | cease-desist | notice-to-quit | breach-of-contract), and what the full letter includes. No letter is drafted here — this is routing, not drafting. For legal and consumer-rights agents with small per-call budgets.

## Output

Returns a routing verdict indicating whether the letter engine supports the described situation, the specific letter type it would draft (demand, cease-and-desist, notice-to-quit, or breach-of-contract), and a description of what the full drafted letter would include — without producing the actual letter.
