Gnosis
Gnosis Chain on-chain read: a contract's event logs, filtered by topic and block range. Returns raw event logs for one Gnosis contract via eth_getLogs. Takes address (0x+40 hex), optional topic0 (0x+64 hex), optional blocks (last N, default 10).
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.
Live 402 challenge
Captured by the enrichment pass, not read just now. Prices can change — always read the 402 the endpoint answers with.

"error": "payment required: retry with a PAYMENT-SIGNATURE header built from one of `accepts`"

The payment requirements as published to the catalog. Read the live 402 before paying — a price here is a claim, not a quote.
Pay 0.003 USDC on Base to 0xBF32…Aa035. The signed payment is good for 1 minute.

GET api.roundhouseai.io/v0/endpoints
This endpoint's own trailing-30-day call count, as published by the upstream catalog and snapshotted daily. 11 snapshots so far. Verified volume counts only settlements with an on-chain EIP-3009 marker.
Show the promptHide the prompt
Using Roundhouse, look up the x402 service Gnosis 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=Gnosis' 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.arysphere.com/v1/ventures/x402_chain_reads_v1/gnosis_eth_getlogs, 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.
