Hi!

The id that required for the endpoint /coins/{id}/contract/{contract_address}/market_chart/, should be the id of the platform issuing tokens (not the coin id). It is defined in the description of the parameter for the endpoint at CoinGecko API doc (https://www.coingecko.com/api/docs/v3):

The id of the platform issuing tokens (See asset_platforms endpoint for list of options)

Using as id: ethereum (found from /asset_platforms endpoint), it seems to response properly (https://api.coingecko.com/api/v3/coins/ethereum/contract/0x1f9840a85d5af5bf1d1762f925bdaddc4201f984/market_chart/?vs_currency=usd&days=7):
