Asin for Hermes Agent
Gives Hermes Agent tools to search Amazon and read a product's price history and offers, through the Asin API.
Install
hermes plugins install asin
Hermes asks for ASIN_API_KEY during the install. Create a key in the Asin dashboard.
Tools
| Tool | What it does |
|---|---|
asin_search_amazon | Search an Amazon store and return products with their ASIN, title, price, currency, rating and review count. |
asin_price_history | Get the price history Asin has recorded for an Amazon product: lowest, highest and average price, and the dated price points. Empty when Asin has no history for the product yet. |
asin_get_offers | Get the offers Asin has already collected for an Amazon product: Amazon's own price, the lowest new and used prices, and each seller's offer. Empty when Asin has not checked the product yet. |
The tools are hidden from the model until the API key is set.
What it does on your machine
- Network: calls
https://www.asin.devonly, with yourASIN_API_KEY. Calls can use credits on your Asin account (pricing). - Credentials: reads the key only through Hermes's secret scope. It stores nothing.
- Nothing else: no files written, no processes started, no telemetry, no self-update. Standard library only, no dependencies.
Development
python -m pytest
The tests mock the network and run without Hermes installed.
