Parameters
| Parameter | Type | Required | Description |
|---|---|---|---|
| id | string | No | One or more comma-separated CoinMarketCap cryptocurrency IDs. Example: "1,2" |
| aux | string | No | Optionally specify a comma-separated list of supplemental data fields to return. Pass `urls,logo,description,tags,platform,date_added,notice,status` to include all auxiliary fields. |
| slug | string | No | Alternatively pass a comma-separated list of cryptocurrency slugs. Example: "bitcoin,ethereum" |
| symbol | string | No | Alternatively pass one or more comma-separated cryptocurrency symbols. Example: "BTC,ETH". At least one "id" *or* "slug" *or* "symbol" is required for this request. Please note that starting in the v2 endpoint, due to the fact that a symbol is not unique, if you request by symbol each data 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. |
| address | string | No | Alternatively pass in a contract address. Example: "0xc40af1e4fecfa05ce6bab79dcd8b373d2e436c4e" |
| skip_invalid | string | No | Pass `true` to relax request validation rules. When requesting records on multiple cryptocurrencies an error is returned if any invalid cryptocurrencies are requested or a cryptocurrency does not have matching records in the requested timeframe. If set to true, invalid lookups will be skipped allowing valid cryptocurrencies to still be returned. |

Metadata v1 (deprecated)
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/info 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.
