Search for Entity Names

post

Search for entity names to use in other v1 endpoints that support entity_name parameters.

This endpoint helps users find the correct entity name format when they want to query by entity instead of address. Many endpoints accept either address or entity_name as parameters, but entity names must match exactly. This search endpoint makes it easy to find the right entity name.

Key Features:

• Case-insensitive search that matches anywhere in the entity name

• Returns up to 100 results ordered alphabetically

• Minimum 2 character search query required

• Free endpoint (0 credits)

Use Cases:

1. Find entity names for profiler endpoints: Search "vitalik" to find "Vitalik Buterin" for use in address balance or transaction queries

2. Discover exchange entities: Search "binance" to find all Binance-related entities

3. Locate fund entities: Search "jump" to find "Jump Trading" and related entities

Example Usage:

{
  "search_query": "vitalik"
}

Response:

{
  "data": [
    {"entity_name": "Vitalik Buterin"},
    {"entity_name": "Vitalik Buterin: Charity"}
  ]
}

Note: This endpoint does not support pagination as results are capped at 100 items.
