Binance Tokenized Securities Info Skill

Overview

API	Function	Use Case
Token Symbol List	List all tokenized stocks	Browse Ondo supported tickers, filter by type
RWA Meta	Tokenized stock metadata	Company info, concepts, attestation reports
Market Status	Overall market open/close	Check if Ondo market is currently trading
Asset Market Status	Per-asset trading status	Detect corporate actions (earnings, dividends, splits, mergers)
RWA Dynamic V2	Full real-time data	On-chain price, holders, US stock fundamentals, order limits
Token K-Line	Candlestick charts	OHLC data for on-chain token price technical analysis

Recommended Workflows

Scenario	Steps
Look up a stock's fundamentals and on-chain data	API 1 (get chainId + contractAddress by ticker) → API 5 (dynamic data)
Check if a stock token is tradable	API 3 (overall market status) → API 4 (per-asset status with reason code)
Research a tokenized stock	API 1 (find token) → API 2 (company metadata + attestation reports)
Get K-Line chart data	API 1 (find token) → API 6 (K-Line with interval)

Use Cases

1. List Supported Stocks: Get all Ondo tokenized tickers with chain and contract info
2. Company Research: Get company metadata, CEO, industry, concept tags, and attestation reports
3. Market Status Check: Determine if the Ondo market is open, closed, or in pre/post-market session
4. Corporate Action Detection: Check if a specific asset is paused or limited due to earnings, dividends, stock splits, mergers, or maintenance
5. Real-Time Data: Get on-chain price, holder count, circulating supply, US stock P/E, dividend yield, 52-week range, and order limits
6. Technical Analysis: Fetch token K-Line (candlestick) data with configurable intervals and time ranges

Key Concept: Token ≠ Share

Each token represents multiplier shares of the underlying stock, not exactly 1 share. Most tokens have a multiplier near 1.0 (cumulative dividend adjustment), but stock-split tokens can be 5.0 or 10.0 (e.g. multiplier = 10.0 means 1 token = 10 shares).

referencePrice = tokenInfo.price ÷ sharesMultiplier

See Notes §6 for common multiplier categories.

API 3: Market Status

Method: GET

URL:

https://www.binance.com/bapi/defi/v1/public/wallet-direct/buw/wallet/market/token/rwa/market/status/ai

Request Parameters: None

Headers: Accept-Encoding: identity

Example:

curl 'https://www.binance.com/bapi/defi/v1/public/wallet-direct/buw/wallet/market/token/rwa/market/status/ai' \
  -H 'Accept-Encoding: identity' \
  -H 'User-Agent: binance-web3/1.1 (Skill)'

Response:

{
  "code": "000000",
  "data": {
    "openState": false,
    "reasonCode": "MARKET_PAUSED",
    "reasonMsg": "Paused for session transition",
    "nextOpen": "2026-03-23T08:01:00Z",
    "nextClose": "2026-03-23T13:29:00Z",

    "nextCloseTime": 1774272540000
  },
  "success": true
}

Note: The sample above is captured with openState=false (market closed/paused), so nextOpen is earlier than nextClose.

Response Fields (data):

Field	Type	Description
openState	boolean	Whether the Ondo market is currently open for trading
reasonCode	string|null	Reason code if market is not in normal trading state (see Reason Codes)
reasonMsg	string|null	Human-readable reason message

nextOpenTime	number	Next market open time from current state (Unix timestamp in ms)
nextCloseTime	number	Next market close time from current state (Unix timestamp in ms)

Interpretation: These fields are state-dependent. When openState=true, nextClose is expected to be earlier than nextOpen (market closes before the next open). When openState=false, nextOpen is expected to be earlier than nextClose (market opens before the next close).

User Agent Header

Include User-Agent header with the following string: binance-web3/1.1 (Skill)

Notes

1. volume24h in tokenInfo is misleading: tokenInfo.volume24h from the RWA Dynamic API returns the US stock daily trading volume in USD, not the on-chain DEX trading volume. For actual on-chain buy/sell volume, use the Binance on-chain dynamic API (/market/token/dynamic/info) with volume24hBuy + volume24hSell fields instead.

2. dividendYield is a percentage value, not a raw decimal: A value of 0.27 means 0.27% dividend yield.

3. Icon and report URLs are relative paths — prepend domain to use: The API returns relative paths for icon, dailyAttestationReports, and monthlyAttestationReports (e.g. /images/web3-data/public/token/logos/...). To construct the full URL, prepend https://bin.bnbstatic.com. Example: /images/web3-data/public/token/logos/<TOKEN_ID>.png → https://bin.bnbstatic.com/images/web3-data/public/token/logos/<TOKEN_ID>.png.

4. No API key required: All endpoints are public APIs. No authentication needed.

5. Multi-chain deployments: Each supported stock may be deployed on multiple chains (e.g. both Ethereum and BSC). stockInfo and tokenInfo.price are identical across chains. tokenInfo.totalHolders is aggregated cross-chain. tokenInfo.circulatingSupply and tokenInfo.marketCap are chain-specific.

6. multiplier / sharesMultiplier — critical for price comparison: Each token represents multiplier shares of the underlying stock, not exactly 1 share. The multiplier starts at 1.0 and increases over time as cash dividends are reinvested (cumulative dividend adjustment). Some tokens also reflect stock splits (e.g. multiplier = 10.0 means 1 token = 10 shares).

   Formula:

   referencePrice = tokenInfo.price ÷ sharesMultiplier

   tokenInfo.price and stockInfo.price come from different sources (on-chain oracle vs stock feed) and update at different frequencies, so a small premium/discount (typically within ±0.1%) is normal.

   Common multiplier categories:

   Multiplier	Cause
   Exactly 1.0	No dividends paid yet, or newly listed
   Slightly above 1.0	Cumulative cash dividend reinvestment (grows over time)
   5.0, 10.0	Stock split reflected in token structure

   The exact multiplier value changes over time as dividends accumulate. Always read it from the API at query time — never hardcode.
