Arkham Intel API (1.0.0)

Arkham Intelligence official API documentation

The Arkham API provides direct query access to Ultra, our proprietary AI-powered algorithmic address matching engine, enabling sophisticated users to customize data flows and integrate them into their existing systems.

Through the API, users can write custom queries to access a list of Arkham labels, as well as transaction logs and historical balance data for addresses and entities.

Institutions that onboard to the Arkham Exchange automatically qualify for access to this API.

The deprecated API documentation is available here in multiple languages; however, please note that it is no longer being updated.

⚠️ IMPORTANT: API-Key

All API requests MUST include a valid API-Key header. Requests without this header will be rejected with an unauthorized response.

To authenticate with Arkham's API, simply provide a valid API-Key in the header of your request. To apply for API access to our platform, visit: https://info.arkm.com/api-platform.

Endpoints

Our root URL is https://api.arkm.com.

Rate limits

Our API uses tier-based rate limits with different limits for different endpoints:

Standard Rate Limits

For the Basic API tier, most endpoints allow up to 20 requests per second with a small additional burst allowance for occasional spikes beyond that threshold.

Heavy Endpoints Rate Limits

Some resource-intensive endpoints have lower rate limits of 1 request per second:

  • /transfers
  • /swaps
  • /counterparties/address/{address}
  • /counterparties/entity/{entity}
  • /token/top_flow/{id}
  • /token/top_flow/{chain}/{address}
  • /token/volume/{id}
  • /token/volume/{chain}/{address}
  • /transfers/histogram

Note: These heavy endpoints are computationally intensive and query large amounts of data, hence the stricter rate limits to ensure platform stability.

If you are consistently hitting the default rate limit we have set for our API you can apply for a rate limit increase here.

Security and Privacy

All data on our platform—including your private labels—is stored securely, using state-of-the-art encryption both at rest and in transit, along with strict access controls to ensure your information remains confidential. For further details on our security and privacy measures, please refer to our Privacy Policy.

Transfers

Provides endpoints for retrieving blockchain transfer and swap activity. These include detailed transfer lists, aggregated histograms for analyzing transfer trends over time, and DEX swap data, all filterable by various query parameters.

Operations

Get a simple histogram of transfers (Public)

Request

Returns a simplified aggregated histogram of transfers over time. This is a public endpoint with basic rate limiting.

Note: For the full-featured histogram endpoint with all filter options, use /transfers/histogram which requires API authentication.

Get a detailed histogram of transfers (API Only)

Request

Returns an aggregated histogram of transfers over time (count and USD values) based on the same filter parameters used in /transfers.

⚠️ This endpoint requires API tier authentication (not just API key)

Rate Limit: This endpoint has a stricter rate limit of 1 request per second.

Additional parameter:

  • granularity: "1h" or "1d" (if the range exceeds 30 days, "1h" is invalid).

Filter parameters (same as /transfers, minus pagination/sorting):

  • base: Filter by specific entity or address. For example, "0x123abc" or "binance".
  • chains: Specify a comma-separated list of chains (e.g. "ethereum,bsc").
  • flow: Direction of the transfer. Valid values are "in", "out", "self", or "all".
  • timeLast: Filter from a recent duration (e.g. "24h", "7d", "30d", etc.).
  • timeGte/timeLte: Filter from/to a specific timestamp in milliseconds.
  • valueGte/valueLte: Numeric filters on the raw token amount.
  • usdGte/usdLte: Numeric filters on the historical USD value of the transfer.
  • from: Comma-separated list of addresses, entities, or deposit services for the 'from' side.
  • to: Comma-separated list of addresses, entities, or deposit services for the 'to' side.
  • tokens: Comma-separated list of token addresses or token IDs. E.g. "ethereum", "usd-coin", or "0x...tokenAddress".
  • counterparties: Comma-separated list of addresses or entities to treat strictly as counterparties (only base <-> counterparty transfers).
