Uniswap V3 liquidity distribution for an Ethereum pool, read on-chain: tokens, fee tier, tick spacing, current tick and price (both directions, decimals applied), in-range liquidity, and every initialized tick within a window around the price with its price, liquidityNet and the active liquidity of the range above it — the shape of concentrated liquidity. Default pool: USDC/WETH 0.05%.

Paid to

0xb8491F953e6860D3b5840b73c60883Ff099ceAfA

The wallet the 402 directs payment to. Its whole payment record — every payer, every chain — is on the merchant page.

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.

Accepts

The payment requirements as published to the catalog. Read the live 402 before paying — a price here is a claim, not a quote.

Show the prompt

Using Roundhouse, look up the x402 service SiteCheck Crypto & Finance 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=SiteCheck%20Crypto%20%26%20Finance'
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://api.chainmarket-api.workers.dev/api/crypto/uniswap-v3-ticks, 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.
