summary: Point-in-time financial feeds for AI agents.
description: 'Every record carries observed_at (when this pipeline first saw it) separately from happened_at (when the event occurred). Records that predate a feed are labelled provenance="pre-existing" with a null observed_at rather than given a fabricated date. Three tiers on the same handlers: free (delayed, capped), subscription token, and x402 pay-per-call in USDC on Base or Arbitrum One. Research data, not investment advice.'

summary: US Congress stock transactions
description: 'US Congress stock transactions from official Senate ePTR and House Clerk disclosures (public domain). Every record carries happened_at (transaction date), disclosed_at (filing date) and observed_at (when this pipeline first saw it). Because the STOCK Act permits ~45 days between trade and disclosure, disclosed_at is the field to use for point-in-time work. Senate data is parsed to ticker level; House filings are metadata only.

description: 'Robinhood Chain (chain id 4663) token launches that cleared a first-hour activity floor, with the early-buyer cohort: the first ~25 distinct wallets that bought (transaction sender, never the router), each with block delta from launch and quote spent. Every launch is graded at 24h and 7d (price multiple vs first buy, liquidity, holders). Launchpad is identified from the Uniswap v4 hook. Recorded forward from 2026-09-03 straight from chain logs: happened_at is the launch block time, observed_at is when the cohort was banked. Not backfilled.
