Scrapling x402 Data Store

Whale exchange netflow signal: on-chain whale transfers (>= $100k) on Ethereum, Base, Arbitrum, Polygon and Solana classified with exchange wallet labels as EXCHANGE_INFLOW_BEARISH (to an exchange), WHALE_ACCUMULATION_BULLISH (exchange to private wallet), INTERNAL_EXCHANGE_SHUFFLE (excluded) or UNLABELED, with per-token inflow/outflow/net USD and a signal, plus a perps section with Hyperliquid whale taker flow per coin. Params chain (all|ethereum|base|arbitrum|polygon|solana|hyperliquid), token (symbol or contract), window (1h|24h|7d, default 24h), limit. Labels from exchange proof-of-reserves lists and open label datasets; each move cites its label source

Provider

The payTo wallet does not resolve to a registered ERC-8004 agent. That is not a verdict on the service — most of the catalog is unregistered.

Hand this page to an agent

Copy the prompt and paste it into Claude, an MCP client or your own agent — it will vet this service and call it over the free read API. No key, no account.

GET api.roundhouseai.io/v0/endpoints

This endpoint's own trailing-30-day call count, as published by the upstream catalog and snapshotted daily. 3 snapshots so far. Verified volume counts only settlements with an on-chain EIP-3009 marker.

Show the prompt
Using Roundhouse, look up the x402 service Scrapling x402 Data Store and tell me whether it is
worth paying: what a call costs, whether the endpoint answered when last probed, and what
its payment record actually shows.

curl -s 'https://api.roundhouseai.io/v0/endpoints?q=Scrapling%20x402%20Data%20Store'
curl -s 'https://api.roundhouseai.io/v0/merchants/<the payTo wallet returned above>'

Then call it: read the price from the live 402 at https://scraplingdata.xyz/v1/signals/whale-netflow, never from
a cached figure, and pay with an x402 client.

The /v0 API needs an API key (`authorization: Bearer rh_live_…`) on everything except
/v0/unified* and /v0/endpoints. Either pay over x402 (mint a personal key for $0.01 at
GET https://api.roundhouseai.io/v0/test/x402), or ask me for an organization key, which I create at
https://roundhouseai.io/dashboard/connections. If you have neither, ask before going further.

If you do not have Roundhouse tools or skills installed, read
https://roundhouseai.io/skill.md first — it is the whole procedure.
