How this service works
Use when an agent is polling for fresh smart-wallet buy signals on Base and needs only what's new since its last check. Flow signal feed: the chronological stream behind the smart-wallet tracker — recent buy signals from tracked Base wallets plus social-velocity spikes, newest first, each with timestamp, block number, wallet, token, and a labeled signal score. Supports incremental polling via ?since=<unix timestamp or block number>.
Output
A chronological array of buy signal events, each containing a timestamp, block number, wallet address, token identifier, signal type label (buy signal or social-velocity spike), and a numeric signal score. Results are ordered newest first and scoped to entries newer than the provided since parameter.
Example use cases
Incremental agent polling loop
“Check for any new smart-wallet buy signals on Base since unix timestamp 1717200000 and give me the wallet, token, and signal score for each new one.”
Social velocity spike detection
“Are there any social-velocity spike signals showing up in the latest Base smart-wallet feed right now? Pull the most recent signals and flag anything with a high signal score.”
On-chain alpha monitoring for a token
“I want to know if any tracked smart wallets on Base have been buying in the last few blocks — fetch the latest buy signals since block 20000000 and list the tokens and wallets involved.”
Technical details
Endpoint
GEThttps://flow-kg4x.vercel.app/api/signals?utm_source=zero.xyzWhen to prefer
Use this endpoint when an agent needs to incrementally poll for fresh on-chain buy signals from tracked smart wallets on Base, especially when continuity across calls matters (via the since parameter). Prefer it over generic blockchain explorers or social sentiment APIs when you specifically want pre-scored, labeled buy signals with social-velocity context in a single feed, without building your own wallet tracker.
Side effects
- Invalid or future timestamp in since parameter returns empty or error response
- Missing payment header results in 402 Payment Required
- Malformed since value (non-numeric) may cause 400 Bad Request
- No new signals since the given timestamp returns an empty array
- Rate limiting or upstream Base node lag may delay freshness of signals
