For partners

Read what the Cadea contracts recorded on Robinhood Chain from one API: plates, listings, auctions, coins, leaderboards and the demand board. It only reads; every write stays in the visitor’s own wallet.

Anonymous, with the headers
curl -i "https://cadea.family/api/v1/status"
With a key, in the x-api-key header
curl -H "x-api-key: vk_<id>_<secret>" \
  "https://cadea.family/api/v1/plates?status=listed&sort=price_asc&limit=5"
Or as a Bearer token
curl -H "Authorization: Bearer vk_<id>_<secret>" \
  "https://cadea.family/api/v1/leaderboards?season=current"

Addresses come back in lower-case hex, amounts in wei as decimal strings. A list takes limit and offset. An unknown or revoked key is refused with 401; it is never served as anonymous.

Keysfor partners that need more

Keys are issued by the Cadea team. There is no form on this site to request one yet.

A key belongs to one named partner and carries its own limit a minute. It looks like vk_<id>_<secret>; the service keeps only a hash of it, so a lost key is replaced rather than recovered, and any key can be revoked.

Reading without a key works for everything on this page. A key only raises the limit.

Coming laterfor launchpads that build on Cadea

The ticker widget

Coming soon

One snippet for a launchpad’s create form: as a creator types a ticker, it shows the plate that spells it, for sale or to grind, with every action signed in the creator’s own wallet.

A partner share on chain

Coming soon

A share of the launch fee paid by the contract to a launchpad that launches through Cadea. Until it exists, the referral shares on the fees page are what a referrer receives.

Launching through Cadea today works the same for everyone: launch a coin and read the fees.
