# Romny Crypto Alerts – Alert Factor Library

> Romny Crypto Alerts – Alert Factor Library is a paid API for AI agents from api2.romny.dpdns.org, paid per call via x402, $0.1/call, status unknown (last checked 2026-10-16).

Returns the list of enabled atomic alert condition factors (building blocks) available for constructing crypto perpetual trading alerts

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 romny-crypto-alerts-alert-factor-library-040594c2
```

Example prompt: What atomic alert conditions are currently enabled in Romny's crypto alert system — can you pull the full list of available factors I can use to build my trading rules?

## When to prefer this

Use this endpoint first when you need to discover what alert conditions are available before constructing or validating alert rule expressions. It is the prerequisite lookup step before calling the sibling endpoint for AND/OR rule combinations. Prefer this over generic crypto data APIs when you specifically need the Romny alert condition vocabulary.

## Known failure modes

- Payment required (402): caller must pay 0.1 USDC via x402 protocol before receiving data
- Empty or minimal factor list if no factors are currently enabled on the server
- Network or DNS failure on api2.romny.dpdns.org (dynamic DNS, may be unstable)
- Unexpected schema or empty response if the service version changes

## How this service works

Enabled alert factor library (atomic conditions)

## Output

A structured list of enabled atomic alert factor definitions — the primitive/building-block conditions available for composing crypto perpetual alert rules via AND/OR expressions. Each factor describes an atomic condition type that can be referenced when constructing alert rules.
