Answer: Was this bounty award actually paid, when, and with which transaction? Join an owned BountyBook or Taskmarket award observation to a Base transaction receipt. A paid result requires a successful receipt and a Base USDC Transfer log to the stored winner. If the award has no confirmed transfer, state that no payout proof was observed. Coverage includes only award IDs in the owned wallet-win store. Taskmarket does not expose payout transaction hashes. BountyBook settlement proof requires a stored payout hash and a matching Base USDC Transfer. Live owned-store depth: 378413 award observations over 282 award subjects from 2026-08-28T09:55:53.360976+00:00 to 2026-09-15T06:01:03.268411+00:00. The store has 39833 Base observations over 440 award subjects from 2026-08-28T18:01:07.137047+00:00 to 2026-09-07T21:01:35.407329+00:00.

0x276efA09388fB1578A6c415B8F90D26fdfCe0CF2The 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.
Live 402 challenge
Captured by the enrichment pass, not read just now. Prices can change — always read the 402 the endpoint answers with.

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 promptHide the prompt
Using Roundhouse, look up the x402 service bounty-signals.krimskrams.xyz 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=bounty-signals.krimskrams.xyz' 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://bounty-signals.krimskrams.xyz/v1/award-settlement, 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. Mint a personal key for $0.01 at GET https://api.roundhouseai.io/v0/test/x402, or use an organization key from https://roundhouseai.io/dashboard/team. If you do not have Roundhouse tools or skills installed, read https://roundhouseai.io/skill.md first — it is the whole procedure.
