-# GoldRush API
-
-## Overview
-GoldRush by Covalent provides blockchain data across 100+ chains through a unified REST API, real-time WebSocket streams, a CLI, and an x402 pay-per-request proxy. This skill enables AI agents to query wallet balances, token prices, transaction history, NFT holdings, and DEX pair data without building chain-specific integrations.
-
-## When to Use This Skill
-- Retrieving wallet token balances or total portfolio value across any chain
-- Fetching transaction history or decoded event logs for an address
-- Getting current or historical token prices (USD or native)
-- Monitoring DEX pairs, liquidity events, and real-time OHLCV candles via WebSocket
-- Building block explorers, portfolio dashboards, tax tools, or DeFi analytics
-- Accessing on-chain data with no signup via x402 pay-per-request
-
-## How It Works
-
-### Step 1: Get credentials
-Sign up at https://goldrush.dev for a free API key. For agent-native no-signup access, use the x402 proxy instead.
-
-### Step 2: Set your API key
-```bash
-export GOLDRUSH_API_KEY="your_api_key_here"
-```
-
-### Step 3: Query data
-
-**REST API (most endpoints):**
-```bash
-# Wallet token balances on Ethereum
-curl -H "Authorization: Bearer $GOLDRUSH_API_KEY"   "https://api.covalenthq.com/v1/eth-mainnet/address/0xADDRESS/balances_v2/"
-```
-
-**CLI (quick terminal queries):**
-```bash
-npx @covalenthq/goldrush-cli balances --chain eth-mainnet --address 0xADDRESS
-```
-
-**SDK (in code):**
-```javascript
-import GoldRushClient from "@covalenthq/client-sdk";
-const client = new GoldRushClient(process.env.GOLDRUSH_API_KEY);
-const resp = await client.BalanceService.getTokenBalancesForWalletAddress(
-  "eth-mainnet", "0xADDRESS"
-);
-```
-
-## Examples
-
-### Example 1: Token Balances
-```bash
-curl -H "Authorization: Bearer $GOLDRUSH_API_KEY"   "https://api.covalenthq.com/v1/eth-mainnet/address/0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045/balances_v2/"
-```
-
-### Example 2: Token Price History
-```bash
-curl -H "Authorization: Bearer $GOLDRUSH_API_KEY"   "https://api.covalenthq.com/v1/pricing/historical_by_addresses_v2/eth-mainnet/USD/0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48/"
-```
-
-### Example 3: Transaction History
-```bash
-curl -H "Authorization: Bearer $GOLDRUSH_API_KEY"   "https://api.covalenthq.com/v1/eth-mainnet/address/0xADDRESS/transactions_v3/"
-```
-
-### Example 4: Real-time OHLCV via WebSocket
-```javascript
-// Stream live price candles for a token pair
-const ws = new WebSocket("wss://streaming.covalenthq.com/v1/eth-mainnet/ohlcv");
-ws.on("message", (data) => console.log(JSON.parse(data)));
-```
-
-## Best Practices
-✅ Use chain slugs: `eth-mainnet`, `matic-mainnet`, `base-mainnet`, `bsc-mainnet` — full list at https://goldrush.dev/docs/networks
-✅ Store API key in `GOLDRUSH_API_KEY` env var — never hardcode
-✅ Use WebSocket streams for real-time data rather than polling REST
-✅ Use SDK cursor pagination for large result sets
-❌ Don't use x402 for high-volume use cases — get a standard API key instead
-❌ Don't use chain IDs (e.g., `1`) — use chain slugs (e.g., `eth-mainnet`)
-
-## Security & Safety Notes
-- API key in `GOLDRUSH_API_KEY` environment variable only
-- x402 payments use USDC on Base — set spending limits before autonomous agent use
-- Read-only data API — no write operations, no transaction signing
-
-## Common Pitfalls
-
-**Problem:** 401 Unauthorized  
-**Solution:** Ensure API key is in `Authorization: Bearer` header, not query string
-
-**Problem:** `chain_name not found`  
-**Solution:** Use chain slug format — see https://goldrush.dev/docs/networks
-
-**Problem:** Empty results for new wallet  
-**Solution:** Some endpoints require on-chain activity; new wallets with no transactions return empty arrays, not errors
