Chainlink Implied-price Composite Adapter

An adapter that fetches the median value from any two sets of underlying adapters, and divides the results from each set together.

Configuration

The adapter takes the following environment variables:

Required?	Name	Description	Options	Defaults to
	[source]_ADAPTER_URL	The adapter URL to query for any [source]

Running

See the Composite Adapter README for more information on how to get started.

Input Params

Required?	Name	Description	Options	Defaults to
✅	dividendSources	An array (string[]) or comma delimited list (string) of source adapters to query for the dividend value
	dividendMinAnswers	The minimum number of answers needed to return a value for the dividend		1
	dividendInput	The payload to send to the dividend sources		{}
✅	divisorSources	An array (string[]) or comma delimited list (string) of source adapters to query for the divisor value
	divisorMinAnswers	The minimum number of answers needed to return a value for the divisor		1
	divisorInput	The payload to send to the divisor sources		{}

Each source in sources needs to have a defined *_ADAPTER_URL defined as an env var.

E.g. for a request with "dividendSources": ["coingecko", "coinpaprika"], you will need to have pre-set the following env vars:

COINGECKO_ADAPTER_URL=https://coingecko_adapter_url/
COINPAPRIKA_ADAPTER_URL=https://coinpaprika_adapter_url/
