Output
A JSON object containing blockchain chains supported by the pump/spread data service, with optional filtering by chain name. Typically includes chain identifiers and metadata useful for determining which networks are queryable for live SOL multi-venue spread data.
Example use cases
Discover Solana chain availability
“Check if Solana is listed as a supported chain for the pump multi-venue spread data API — filter the chains list by 'solana' and tell me what comes back.”
Enumerate all supported networks
“List every blockchain network this x402 pump data service supports so I know which ones I can query for live spread information.”
Agent chain compatibility check
“Before I start pulling live multi-venue spread data, can you grab the full list of supported chains from the pump endpoint so I can confirm my target network is available?”
