Parameters

ParameterTypeRequiredDescription
idstringYesThe Category ID. This can be found using the Categories API.
limitstringNoOptionally specify the number of coins to return. Use this parameter and the "start" parameter to determine your own pagination size.
startstringNoOptionally offset the start (1-based index) of the paginated list of coins to return.
convertstringNoOptionally calculate market quotes in up to 120 currencies at once by passing a comma-separated list of cryptocurrency or fiat currency symbols. Each additional convert option beyond the first requires an additional call credit. A list of supported fiat options can be found [here](#section/Standards-and-Conventions). Each conversion is returned in its own "quote" object.
convert_idstringNoOptionally calculate market quotes by CoinMarketCap ID instead of symbol. This option is identical to `convert` outside of ID format. Ex: convert_id=1,2781 would replace convert=BTC,USD in your query. This parameter cannot be used when `convert` is used.

CoinMarketCap API /v1/cryptocurrency/category: frequently asked questions

Category

It costs Free per request, settled in USDC on Solana. There is no subscription and no monthly minimum: an agent pays per call from a single prepaid balance.

The agent calls GET /v1/cryptocurrency/category through the Proxygate gateway with the Proxygate CLI, SDK, or MCP server. Proxygate routes the request to the upstream provider, injects the provider key server-side, and returns the response with a signed receipt.

No. The upstream provider key never leaves the Proxygate gateway. Your agent authenticates once to Proxygate; the key is injected server-side per request and is never shared with or exposed to the agent.
