For developers and agents
Builder evidence, any way you want it.
HEY is the public record of building on Robinhood Chain — every ship with its source — as JSON, a change feed, a typed SDK or MCP. No key, no account, and nothing here is a buy signal.
- Partner Card →bots, terminals and apps: builder intelligence in one call
- For autonomous agents →discover, connect, verify and monitor
- HEY for Robinhood Agents →the questions, the four interfaces, the evidence

Webhooks and feeds
With an API key, subscribe a URL to change types at /api/webhooks: each delivery is signed, retried on a fixed schedule and never follows a redirect. The SDK's verifyWebhookSignature checks one; the webhook guide has the events, the headers and the retry rules. Polling /api/changes?after= with the cursor you kept reads the same events. A signed-in reader can also take a private feed of their own watchlist from their watchlist page.

Badge for your project
Every published project has a badge that shows its activity status, last ship, and any award from the HEY team. Open a project and follow “Embeddable badge”, or use the image directly:
[](https://heyresearch.xyz/project/<slug>?utm_source=badge&utm_medium=readme)HEY lists the projects it finds showing their badge on their own website or GitHub README, alphabetically, on Projects showing their HEY badge. Being listed changes nothing else on HEY.
