# Nacian AI DeFi Alert

> Nacian AI DeFi Alert is a paid API for AI agents from api.nacian.app, paid per call via x402, $0.010926/call, status unknown (last checked 2026-10-12).

Creates time-bounded AI-powered monitoring alerts for DEX and lending protocol metrics across Ethereum, Base, and Arbitrum, triggering a webhook when conditions are met.

## Facts

- Endpoint: POST https://api.nacian.app/alert?utm_source=zero.xyz
- Price: $0.010926/call
- Payment: x402

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 nacian-ai-defi-alert-a071f235 -d '<json body>'
```

Example prompt: Set up a DeFi alert using Nacian to watch the Uniswap V3 ETH/USDC pool on Ethereum and notify my webhook at https://myserver.com/hook if the pool's 24h volume drops below $1M — check every 60 seconds, run for 1440 minutes max, and use the gemini-3-flash model.

## When to prefer this

Choose this endpoint when you need to set up an ongoing, time-bounded automated watch on DeFi protocol metrics (DEX liquidity, lending rates, TVL, volume) and receive a push notification via webhook when conditions are met — rather than performing a one-shot query. Use the sibling analyst endpoint for immediate on-demand data retrieval without alerting.

## Known failure modes

- Invalid webhook URL (not HTTPS) — error event returned
- maxMinutes out of range (below 5 or above 10080) — validation error
- frequencySeconds out of range (below 30 or above 86400) — validation error
- Unsupported protocol or chain combination — AI may fail to create alert or return error content
- Payment not included or insufficient — 402 response before stream begins
- maxOutputTokens below 1500 or above 5000 — validation error
- Webhook endpoint unreachable when condition triggers — silent delivery failure

## How this service works

Nacian AI DeFi Alert — create time-bounded monitoring alerts for DEX and lending protocol metrics. Supported protocols by chain: Ethereum: Uniswap V2, Uniswap V3, Uniswap V4, Sushiswap V2/V3, Pancakeswap V2/V3, Aave V2, Aave V3, Compound V3; Base: Uniswap V3, Sushiswap V2/V3, Pancakeswap V2/V3, Aerodrome V3, Aave V3; Arbitrum: Uniswap V3, Sushiswap V2/V3, Camelot V3, Aave V3, Compound V3.

## Output

A server-sent event stream: first tool-status events showing alert creation progress, then an alert-created event with the alert's UUID, name, expiry timestamp, and 'active' status, followed by a content event with a natural-language summary; errors return a JSON error message event.
