market2000.xyz

Demand-to-supply matching — unmet agent demand crossed against who already sells it. Each row pairs something agents ask for and cannot get with the number of origins already selling in that category, so you can tell a genuine product gap from a distribution problem. A lead list if you already sell there; a build order if nobody does. HOW TO CALL: GET /api/demand/matches?days=7&limit=25 PARAMETERS: days — lookback window, 1-90 (default 7) limit — rows returned, 1-100 (default 25) RESPONSE: matches[] with the wanted path, request volume, bucketed asker count, existing supplier count, field median price, and a verdict. PRICING: $0.10 per call.

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.

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 market2000.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=market2000.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://market2000.xyz/api/demand/matches, 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.
