Horizon Pulse

Name: Horizon Pulse
Price: 0.01 USDC
Availability: InStock

Batch chain checks API: up to 10 checks for one payment. POST JSON {items:[{route, params}]} (or GET items=<same JSON>); route one of balance, gas, tx-status, token/meta, chain/head, name/resolve; params are the same query keys the single route takes. Returns JSON: results [{index, route, status, ok, body}] in request order, count, okCount. Each item runs the single route's handler. Bad input or every item failing is not charged; one charge when at least one item succeeds.

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.

Accepts

The payment requirements as published to the catalog. Read the live 402 before paying — a price here is a claim, not a quote.

Show the prompt

Using Roundhouse, look up the x402 service Horizon Pulse 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=Horizon%20Pulse'
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://horizonpulse.dev/api/batch, 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.
