Flow signal feed: the chronological stream behind the smart-wallet tracker — recent buy signals from tracked Base wallets plus social-velocity spikes, newest first, every entry with timestamp, block number, wallet, token, and a labeled signal score. Supports incremental polling via ?since=<unix timestamp or block number> so each $0.01 call returns only entries newer than the last one consumed.","tags":["trading","defi","base","dex","quotes"],"categoryId":"onchain-data","priceUsd":0.01,"priceScheme":"exact","network":"eip155:8453","payTo":"0xcF8A8350cb42a6680005ca7FF9E485Bb55fa74FA","testnetOnly":false,"calls30d":null,"payers30d":null,"lastCalledAt":null,"startFeeUsd":null,"platformUsageExtra":null,"reportedSuccess30d":null,"pageUrl":null,"firstSeenAt":"2026-10-12T00:08:01.463Z","lastSeenAt":"2026-10-12T00:08:01.463Z","lastProbedAt":"2026-10-12T00:16:00.176Z","embeddedHash":"516bc306cd1557ef70c7819bbbb6d41482b40be49fc408a083bc370d52169763"},"score":{"endpointId":"98367d8affdd285f","computedAt":"2026-10-12T01:46:40.783Z","score":null,"grade":null,"uptime7d":1,"latencyP50Ms":573,"probeCount7d":1,"flags":["no-usage-data"]},"recentProbes":[{"id":27343,"endpointId":"98367d8affdd285f","checkedAt":"2026-10-12T00:16:00.350Z","statusCode":402,"latencyMs":573,"valid402":true,"priceUsd":0.01,"payTo":"0xcF8A8350cb42a6680005ca7FF9E485Bb55fa74FA","error":null,"mcpOutcome":null,"mcpProtocol":null}]}
