aeml-x402
Pay-per-call data signals for AI agents via the x402 protocol (USDC on Base, no API key, no signup). Headline value: (1) pre-joined CROSS-LINE CASCADE — one call surfaces downstream exposure across industries; (2) LEADING signals — the upstream factor before the current state; (3) aggregation / screening convenience over scattered free official sources (USGS/NOAA/EPA/SEC/FDA/EIA/…), pre-cleaned into one schema; (4) verifiable official-source provenance (official timestamp + record_hash) for those who need citable screening evidence. Pure description — no judgment, no prediction; official-sourc

On-chain payments
Payment shape (25 most recent sampled): 24 x402-signed (EIP-3009 transferWithAuthorization, the exact scheme's on-chain signature) · 1 plain transfers (a wallet paying the ordinary way) · 0 other calldata (facilitator batch, smart wallet, or unrelated — not classified).
Peak day 2026-09-07: 71 payments. Last indexed day 2026-09-25: 1. Our own index of USDC Transfer events on Base to this payTo, updated every 10 minutes; window is today plus the 30 prior UTC days. Base USDC only — a seller settling elsewhere reads as quiet here. These figures belong to the address, which 78 listings declare — they are not this route's alone, and must not be summed across listings. Methodology.
