Where the offers sitLog scale. The shaded band is the middle half of the market, $0.0020 to $0.0050.
$0.0010$0.010

Every supplier below carries its index against that rate: 100 is spot, 40 is 60% below it, 310 is 3.1× it. Spot is weighted by how often each endpoint is called, so one wallet listing forty near-identical endpoints cannot move it on listings alone. The cheapest offer here is $0.0010 and the dearest $0.010.

Model families, not versions — publishers rarely pin one, and a gateway lets the caller choose at request time.

Prices are per request, not per token. Of the chat-completion offers in this catalog, 66 state a per-call price and 3 mention per-token pricing at all — one seller’s call is ~128 tokens and the next leaves it unstated, so a $/1M-token comparison would be a number Roundhouse invented rather than one a publisher declared.

Copy the prompt and paste it into Claude, an MCP client or your own agent — it will pick the best provider of this capability over the free read API. No key, no account.

GET app.roundhouseai.io/unified.json?capability=embeddings

Open skill.md
Show the prompt
Using Roundhouse, compare every x402 provider of Text embeddings and pick one for me.
Weigh the price per unit against whether the endpoint answered when last probed, and say
what the cheapest option would cost against the median.

curl -s 'https://app.roundhouseai.io/unified.json?capability=embeddings'

The canonical request and response in that document are the shape every provider is
mapped onto. Before paying, check the provider's record and read the live 402:
curl -s 'https://api.roundhouseai.io/v0/merchants/<the payTo wallet on the offer you choose>'

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://app.roundhouseai.io/dashboard/team.

If you do not have Roundhouse tools or skills installed, read
https://app.roundhouseai.io/skill.md first — it is the whole procedure.
