ChainK9
Read the token's market at one finalized block. A V3 or V4 pool returns pool_version, fee, hook, active liquidity, price and (V3) the coins the pool holds; its positions are NFTs, so holders and lock IDs are refused. A V2 pair returns canonical reserves against WBNB/WETH (PancakeSwap on BSC, Uniswap on Ethereum and Base), LP supply, burned LP and up to ten supplied holders. On BSC, optionally verify up to ten PinkLock V2 simple lock IDs against the pinned BSC contract, exact runtime hash and aggregate LP custody. Reports future, elapsed, withdrawn and unsupported vesting records. No holder/lock discovery or withdrawal simulation; other contract-held LP remains unknown. Lock and holder amounts overlap.
The wallet the 402 directs payment to. Its whole payment record — every payer, every chain — is on the merchant page.

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.

Using Roundhouse, look up the x402 service ChainK9 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=ChainK9' 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.chaink9.com/liquidity-report, 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.
