Returns a JSON object with the tagId, total number of entities bearing that tag (numEntities), total number of associated blockchain addresses (numAddresses), and the number of unique tag parameter variants (numUniqueTagParams). Example: proof-of-reserves tag has 41 entities, 1,469,166 addresses, and 39 unique tag params.
Example use cases
Exchange wallet coverage research
“How many addresses and entities does Arkham have tagged as 'exchange' right now? I want to understand the coverage before I start a wallet monitoring project.”
Proof-of-reserves cluster sizing
“Get me the Arkham tag summary for 'proof-of-reserves' — how many entities, addresses, and unique tag params are in that cluster?”
Comparing tag sizes across labels
“I'm trying to compare how big the 'cex' tag is versus 'dex' on Arkham. Can you pull the tag summaries for both so I can see the entity and address counts?”
Technical details
Endpoint
POSThttps://api.arkm.com/x402/tag/summaryWhen to prefer
Use this endpoint when you need aggregate statistics about a named Arkham intelligence tag — specifically entity count, address count, and parameter diversity — rather than individual wallet or entity details. Prefer this over broader entity search endpoints when you only need top-level tag-level summaries without per-entity data.
Side effects
- Unknown or misspelled tagId returns empty or error response
- Tag exists but has zero entities/addresses if recently created
- x402 payment failure if USDC balance is insufficient
- Rate limiting or authentication errors if API key is invalid
- Network timeout if Arkham backend is under load
