# think.agentutil.net Intent Expander

> think.agentutil.net Intent Expander is a paid API for AI agents from think.agentutil.net, paid per call via x402, $0.003/call, status unknown (last checked 2026-09-15).

Surfaces unstated implicit requirements in a human instruction — backup expectations, permission checks, rollback plans, and compliance needs — before an agent acts on it

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 think-agentutil-net-637fe5aa -d '<json body>'
```

Example prompt: Before I execute 'delete all inactive user accounts from the production database', expand that instruction to surface any implied requirements — like backup expectations, rollback plans, permission checks, or compliance needs — in the context of a SaaS billing domain.

## When to prefer this

Use this endpoint before an agent executes any consequential or irreversible instruction — especially in domains like databases, finance, user management, or infrastructure — when you need to surface the unstated assumptions, safety expectations, and compliance constraints a human would assume but never explicitly state. Prefer this over generic pre-flight checklists when the goal is specifically to infer hidden intent and implied requirements from the raw instruction text itself.

## Known failure modes

- Missing or empty instruction field returns a 400 error
- Overly vague instruction may produce generic or low-specificity requirements
- Domain mismatch may cause irrelevant compliance categories to surface
- Payment failure or 402 response if USDC balance is insufficient
- Ambiguous instruction language may yield incomplete coverage of implied requirements

## How this service works

Intent security — surface the implied requirements humans assume but never state: backup expectations, permission checks, rollback plans, compliance needs

## Output

A structured list of implied, unstated requirements inferred from the instruction — including backup expectations the human assumes will be met, permissions that should be verified, rollback plans that should exist, and compliance or regulatory needs relevant to the domain — helping the agent act safely and completely.
