Entity for an address from the Arkham API

Submitted by:
Arkham Team
This Function returns the entity ID of a given address. The entity ID is a string, and represents a slugified version of the entity's name. For example, Binance -> binance. The address is the only required parameter, and an API key is the only required secret.

Entity IDs are strings representing // slugified version of the entity's name. They can be used in other functions to Arkham's API if // you'd like to find more information about the entity and its on-chain footprint. // An Arkham API key is required to use this function. Apply for one here: const address = args[0] // Validate address input. if (address.length != 42) { throw Error("invalid address") } // Validate required secret. if (!secrets.ARKHAM_API_KEY) { throw Error("api key required") } // Make the request to the /intelligence/address/:address/all endpoint. const url = `${address}/all` const resp = await Functions.makeHttpRequest({url, headers: {'API-Key': secrets.ARKHAM_API_KEY}}) const data = resp["data"] if (resp.error) { console.error(error) throw Error("Request failed") } // Since we used the /all endpoint, we get data in the form of a chain map (see const declaration). // In very rare cases, an address will have a different entity based on the chain. In those cases, // you can choose which chain you'd like to privilege. let entityId = "" for (const [chain, intel] of Object.entries(data).sort()) { // Sort so that output is deterministic. // Choose the chain with the first non-null arkhamEntity field. if (intel.arkhamEntity !== undefined) { entityId = break } } return Functions.encodeString(entityId)
