Scrapling x402 Data Store

Trending meme coins on Base, BNB Chain (bsc) or Solana (pump.fun): tokens ranked by USD volume x volume spike, with price, price change over the window, buys/sells, volume spike vs prior 24h, quote-side liquidity, pool and pool age, plus a go/caution/avoid risk verdict (low liquidity, brand-new pool, no sells seen = possible honeypot, parabolic pump, dump, wash-trading ratio). Built from DEX swap logs we read on-chain every ~15 min (stablecoins, tokenized stocks and majors excluded).

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

No per-endpoint history for this service yet, so this is payments indexed to its PROVIDER's wallet over 30 days. 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/meme/trending, 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.
