# ST0x Tokenized Equities Issuer Registry

> ST0x Tokenized Equities Issuer Registry is a paid API for AI agents from x402-accelerometer-feed.fly.dev, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-18).

Returns the complete issuer registry of ST0x tokenized equity contracts (wrapped ERC-4626 and unwrapped ERC-20) across four chains, keyed by stock ticker, including ISIN, TradingView symbol, receipt vault, and listed flag.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability st0x-tokenized-equities-issuer-registry-36b6f528
```

Example prompt: What's the on-chain contract address for the ST0x tokenized NVIDIA stock — both the wrapped wtNVDA ERC-4626 and unwrapped tNVDA ERC-20 versions — on Base?

## When to prefer this

Use this endpoint when you need authoritative, multi-chain contract addresses for ST0x tokenized equities — especially to resolve a stock ticker to its on-chain token, verify a contract's legitimacy, retrieve ISIN or TradingView metadata, or enumerate all listed tokenized shares. Prefer this over general token lookup services when the specific concern is ST0x-issued tokenized stocks across Base, Ethereum, HyperEVM, or Robinhood Chain.

## Known failure modes

- Registry temporarily unavailable due to upstream issuer source refresh failure
- Stale data if hourly refresh has not yet completed
- Ticker present in registry but unwrapped/receipt fields are null for some chains
- Network timeout reaching the fly.dev host
- Payment not accepted if x402 micropayment fails

## How this service works

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.

## Output

A JSON object keyed by chain (Base, Ethereum, HyperEVM, Robinhood Chain), each containing a count and an array of token entries. Each entry includes ticker, name, ISIN, wrapped ERC-4626 address, unwrapped ERC-20 address, ERC-1155 receipt vault address, TradingView symbol, listed flag, and a legacy field. Also includes issuer name, source URL, as_of timestamp, and a disclaimer.
