How this service works
Is this token heating up or cooling down? Momentum on Base: current block window versus the previous one — activity and volume with a % delta and a heating/cooling/flat trend. ?token=0x...
Output
Returns the token's transfer activity count and volume for the current block window versus the prior block window, a percent delta between the two, and a categorical trend label — heating, cooling, or flat — indicating whether on-chain momentum is increasing, decreasing, or stable.
Example use cases
Pre-trade momentum check
“Before I buy, check whether 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 is heating up or cooling down on Base — give me the activity and volume delta versus the last block window.”
Token alert bot signal filter
“I'm building an alert system — tell me the momentum trend for 0x4200000000000000000000000000000000000006 on Base so I can filter out flat tokens and only flag ones that are heating.”
Compare two tokens' momentum
“Which one has more momentum right now on Base — 0xd9aAEc86B65D86f6A7B5B1b0c42FFA531710b6CA or 0x50c5725949A6F0c72E6C4a641F24049A917DB0Cb? Give me the heating/cooling trend and % volume delta for both.”
Technical details
Endpoint
POSThttps://pulsefeed.dev/momentumWhen to prefer
Choose this endpoint when you need a simple, directional momentum signal for a Base ERC-20 token — specifically the heating/cooling/flat classification with a % delta — rather than raw transfer lists, whale movement, or smart-money flow. It is ideal for filtering tokens by momentum before acting, building alert thresholds, or surfacing trend direction without parsing raw blockchain data.
Side effects
- Invalid or non-ERC-20 token address returns an error or empty result
- Token with no recent activity may return zeroes with a flat trend
- Base RPC node lag may cause stale block window data
- Missing ?token= parameter returns a 400 or descriptive error
- Very new tokens with no prior block window history may lack a valid delta
