Binance Web3 API

Operate Binance Web3 public market and research APIs through UXC with a curated OpenAPI schema. Use when tasks need token search, token metadata/market snaps...

Binance Web3 API Skill

Use this skill to run Binance Web3 public read operations through uxc + OpenAPI.

Reuse the uxc skill for shared execution and error-handling guidance.

Prerequisites

• uxc is installed and available in PATH.
• Network access to https://web3.binance.com.
• Access to the curated OpenAPI schema URL:
  • https://raw.githubusercontent.com/holon-run/uxc/main/skills/binance-web3-openapi-skill/references/binance-web3.openapi.json

Scope

This skill covers the public web3.binance.com endpoints for:

• token search
• token metadata
• token market snapshots
• address holdings
• token security audit
• social hype leaderboard
• unified token ranks
• meme rush ranks
• smart money signals

This skill does not cover:

• Binance Spot / account trading APIs
• Binance Square posting
• K-line candles hosted on https://dquery.sintral.io

Authentication

Most operations are public and do not require API credentials.

Core Workflow

1. Use the fixed link command by default:

   • command -v binance-web3-openapi-cli
   • If missing, create it: uxc link binance-web3-openapi-cli https://web3.binance.com --schema-url https://raw.githubusercontent.com/holon-run/uxc/main/skills/binance-web3-openapi-skill/references/binance-web3.openapi.json
   • binance-web3-openapi-cli -h

2. Inspect operation schema first:

   • binance-web3-openapi-cli get:/bapi/defi/v5/public/wallet-direct/buw/wallet/market/token/search -h
   • binance-web3-openapi-cli post:/bapi/defi/v1/public/wallet-direct/security/token/audit -h

3. Execute operation:

   • key/value: binance-web3-openapi-cli get:/bapi/defi/v5/public/wallet-direct/buw/wallet/market/token/search keyword=bnb chainIds=56 orderBy=volume24h
   • positional JSON: binance-web3-openapi-cli post:/bapi/defi/v1/public/wallet-direct/buw/wallet/market/token/pulse/unified/rank/list '{"rankType":10,"chainId":"56","period":50,"page":1,"size":20}'

Operation Groups

Token Discovery And Market Snapshot

• Search tokens:
  • get:/bapi/defi/v5/public/wallet-direct/buw/wallet/market/token/search
• Fetch token metadata:
  • get:/bapi/defi/v1/public/wallet-direct/buw/wallet/dex/market/token/meta/info
• Fetch token market data:
  • get:/bapi/defi/v4/public/wallet-direct/buw/wallet/market/token/dynamic/info

Rankings And Signals

• Social hype leaderboard:
  • get:/bapi/defi/v1/public/wallet-direct/buw/wallet/market/token/pulse/social/hype/rank/leaderboard
• Unified token rank:
  • post:/bapi/defi/v1/public/wallet-direct/buw/wallet/market/token/pulse/unified/rank/list
• Meme rush rank:
  • post:/bapi/defi/v1/public/wallet-direct/buw/wallet/market/token/pulse/rank/list
• Smart money signals:
  • post:/bapi/defi/v1/public/wallet-direct/buw/wallet/web/signal/smart-money

Research

• Address holdings:
  • get:/bapi/defi/v3/public/wallet-direct/buw/wallet/address/pnl/active-position-list
• Token audit:
  • post:/bapi/defi/v1/public/wallet-direct/security/token/audit

Guardrails

• Keep automation on the JSON output envelope; do not use --text.
• Parse stable envelope fields first: ok, kind, protocol, data, error.
• Binance Web3 responses usually wrap payloads as code, message, success, data; treat code == "000000" as success.
• audit requires a UUID v4 requestId; generate one for every request instead of reusing old IDs.
• Address holdings requires operation-level headers clienttype=web and clientversion=1.2.0; keep them scoped to that operation instead of injecting them host-wide.
• For non-string objects, prefer positional JSON instead of flattening complex filters into many key=value args.
• binance-web3-openapi-cli <operation> ... is equivalent to uxc https://web3.binance.com --schema-url <binance_web3_openapi_schema> <operation> ....
