One prompt gives your assistant the endpoint, the sign-in header and how to wait for a result, so its first script works.
I'm building with the Soldgraph API. It returns sold and for-sale listings from eBay and other resale marketplaces. Read the docs first: https://soldgraph.com/llms.txt OpenAPI spec: https://soldgraph.com/openapi.json Rules for the code you write: - Base URL: https://api.soldgraph.com/v1 - Auth: send the header "Authorization: Bearer <key>". Read the key from the SOLDGRAPH_KEY environment variable. Never put it in browser code. - eBay sold prices: GET /ebay/sold?q=<search words>. Add count=200 for up to 200 rows. - A search often answers 202 with status "pending" and a poll_url. Request https://api.soldgraph.com plus poll_url with ?wait=20 and the same header, until status is "complete" or "failed". - Read result.summary for the median, low and high price. The rows are in result.data, each with title, displayed_price, sold_date and link. - Each completed search uses one request. The free plan has 100 a month, so save results while testing instead of repeating a search. Start with a short script that prints the median sold price for "nintendo switch oled". Then ask me what I want to build.
