How this service works
Use this when you need the same stock from every issuer on Base in one call: send a ticker (NVDA, AAPL, TSLA) and get, per issuer — ST0x (wtNVDA) and Coinbase tokenized stocks (NVDAc, B20) — the genuine contract verified against the issuer's own registry, live price, premium/discount vs the real share in bps, pool depth and 24h volume, the ST0x-vs-Coinbase spread, any direct cross-issuer pool, and every impostor token using the same symbol. xStocks flagged as not on Base.
Output
A structured JSON object with per-issuer entries for the requested ticker, each containing: verified contract address, token symbol, live price in USD, premium/discount vs real share in basis points, best pool details, 24h volume, total liquidity, ST0x vs Coinbase spread, any direct cross-issuer pool, and an impostors array listing unverified tokens using the same symbol with their DEX, liquidity, and reason for flagging. Also includes underlying real-share reference data and a disclaimer.
Example use cases
Best price for tokenized AAPL
“I want to buy tokenized AAPL on Base — can you check both ST0x and Coinbase issuers, show me their live prices, premiums vs the real Apple share, and tell me which pool has the most liquidity?”
Spotting fake TSLA tokens
“Before I trade this TSLA token someone sent me on Base, can you check whether the contract is verified against the issuer's registry and flag any impostor tokens using the TSLA symbol?”
Arbitrage spread between issuers
“Is there a meaningful spread between the ST0x and Coinbase versions of NVDA tokenized stock on Base right now, and is there a direct cross-issuer pool I could use to trade between them?”
Technical details
Endpoint
GEThttps://x402-accelerometer-feed.fly.dev/tokenized-equities/same-stock/:ticker?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a comprehensive, cross-issuer view of a tokenized stock on Base in a single call — especially when you want to compare ST0x and Coinbase tokenized stock prices, verify contract legitimacy, assess pool liquidity, or detect impostor tokens. Prefer this over issuer-specific endpoints when the user has not specified a preferred issuer or when arbitrage, safety checks, or best-execution decisions require seeing all issuers at once.
Side effects
- Unknown or unsupported ticker returns empty issuers array
- Token not yet available on Base returns available:false for that issuer
- Price feed temporarily unavailable returns null price_usd
- No liquidity pools found returns null best_pool and zero volume
- xStocks tokens flagged as not on Base and excluded from main issuers
- Impostor detection may not catch brand-new fraudulent tokens
