Parameters
| Parameter | Type | Required | Description |
|---|---|---|---|
| id | string | No | The CoinMarketCap currency ID of the base cryptocurrency or fiat to convert from. Example: "1" |
| time | string | No | Optional timestamp (Unix or ISO 8601) to reference historical pricing during conversion. If not passed, the current time will be used. If passed, we'll reference the closest historic values available for this conversion. |
| amount | string | Yes | An amount of currency to convert. Example: 10.43 |
| symbol | string | No | Alternatively the currency symbol of the base cryptocurrency or fiat to convert from. Example: "BTC". One "id" *or* "symbol" is required. Please note that starting in the v2 endpoint, due to the fact that a symbol is not unique, if you request by symbol each quote response will contain an array of objects containing all of the coins that use each requested symbol. The v1 endpoint will still return a single object, the highest ranked coin using that symbol. |
| convert | string | No | Pass up to 120 comma-separated fiat or cryptocurrency symbols to convert the source amount to. |
| convert_id | string | No | Optionally 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. |

Price Conversion v2
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 /v2/tools/price-conversion 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.
