datastand.dev
Cheapest-model router: send your token workload and get every current LLM ranked by estimated USD cost, with per-MTok prices, cached-input rates, and context windows. Merges the weekly hand-verified llm-pricing table (every figure carrying its official source URL and verification date) with the daily OpenRouter marketplace catalog — 400+ models — and marks each row `operator-verified` or `marketplace-listed`; `verified_only=1` keeps just the first kind. Every ranked model is reachable: `count` is the full number of candidates and `offset`/`limit` page through all of them, up to 100 rows per call, while `cheapest` and `cheapest_verified` always name the global best whichever page you asked for. `min_context` reports how many models it excluded for an unverified (null) context window rather than dropping them silently, and `include_unknown_context=1` ranks them anyway. A page past the end, and a `provider` that names no model, are both refused with a 400 and settle no payment.

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.

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
This endpoint's own trailing-30-day call count, as published by the upstream catalog and snapshotted daily. 32 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 datastand.dev 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=datastand.dev' 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://datastand.dev/api/llm/route, 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.
