# Agoranome Model-Update Watch

> Agoranome Model-Update Watch is a paid API for AI agents from api.agoranome.com, paid per call via x402, $1/call, status unknown (last checked 2026-10-30).

Monitors your x402 API offer against real Bazaar competitors whenever a panel AI model changes, flagging win-rate drops over 30 days after a single payment.

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 agoranome-model-update-watch-fdec81f9 -d '<json body>'
```

Example prompt: Set up a 30-day model-update watch for my x402 API at https://api.mypricer.com/v1/quote — test it against Bazaar competitors on tasks like 'get me a live price quote for ETH' and send each result to https://hooks.myapp.com/agoranome as they come in.

## When to prefer this

Choose this endpoint when you want ongoing, event-driven competitive monitoring tied specifically to AI model updates — not just a one-time snapshot. It is ideal for x402 API sellers who want to detect win-rate degradation caused by model-preference shifts rather than price changes, and who want results pushed via webhook without managing polling logic themselves. Prefer alternatives like the one-shot Machine Buyer Panel test if you only need a single benchmark and do not need model-update tracking.

## Known failure modes

- Invalid or unreachable resource URL returns an error before the watch is created
- Tasks array empty or exceeds 3 items triggers validation failure
- Webhook URL not HTTPS causes rejection of the notify field
- Payment not received or insufficient USDC causes 402 response with no watch created
- Resource URL not discoverable in Bazaar may result in no competitors found for comparison

## How this service works

Will a new AI model stop buying my x402 API? The model-update watch tests your offer against its real Bazaar rivals with the Machine Buyer Panel now, then re-runs the same test whenever a panel model changes over the next 30 days and flags a drop in your win rate. One payment, no renewal. Status is free at the watch URL; an optional https webhook gets each result.

## Output

Returns a watch object with a unique watch ID, expiry timestamp (30 days out), a public status URL to poll for free, and the number of reruns remaining, plus a baseline win rate with 95% confidence interval from the initial test run against current Bazaar rivals.
