# Agent Trust Utilities Catalog

> Agent Trust Utilities Catalog is a paid API for AI agents from soviet-rica-soldiers-supplemental.trycloudflare.com, paid per call via x402, price unknown, status down (last checked 2026-10-13).

## 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 agent-trust-utilities-catalog-2d8cfe24
```

Example prompt: Can you fetch the free catalog of agent utilities so I can see what's available for Base USDC settlement proofs and x402 usage analysis?

## When to prefer this

Use this endpoint as a free discovery step before committing to a paid call — it tells you exactly what the USDC settlement proof and x402 usage analysis services offer. Prefer it when an agent needs to programmatically inspect available payment utility capabilities without incurring cost, or when building a dynamic tool-selection workflow that needs up-to-date service metadata.

## Known failure modes

- Service unavailable if the Cloudflare tunnel is inactive or expired (temporary trycloudflare.com URL may go offline)
- Empty or malformed catalog if the backing service configuration is incomplete
- Unexpected HTTP 4xx/5xx if the endpoint is misconfigured on the host side
- No query parameters accepted — passing any will be rejected (additionalProperties: false)

## How this service works

Free machine-readable catalog for two paid agent utilities: Base USDC settlement proof and x402 resource repeat-demand versus one-shot usage analysis.

## Output

A machine-readable catalog (likely JSON) listing at minimum two paid agent utility endpoints: (1) a Base USDC settlement proof service and (2) an x402 repeat-demand vs one-shot usage analysis service, along with their descriptions, pricing, and any relevant metadata an agent needs to decide whether to call them.
