Roundhouse

ST0x Tokenized Equities

Use this when you need to resolve a stock ticker to its ST0x on-chain token, or check whether a contract is a genuine ST0x tokenized share: the complete issuer registry for all 54-56 names on each of four chains (Base, Ethereum, HyperEVM, Robinhood Chain) — wrapped (wtNVDA, ERC-4626) and unwrapped (tNVDA, ERC-20) addresses, the ERC-1155 receipt vault, ISIN, TradingView symbol, listed flag. Versioned from the issuer's own registry; refreshed hourly.

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.

Live 402 challenge

Captured by the enrichment pass, not read just now. Prices can change — always read the 402 the endpoint answers with.

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. 7 snapshots so far. Verified volume counts only settlements with an on-chain EIP-3009 marker.

Using Roundhouse, look up the x402 service ST0x Tokenized Equities 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=ST0x%20Tokenized%20Equities'
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://x402-accelerometer-feed.fly.dev/tokenized-equities/st0x/registry, 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.
