## What it does

This skill equips the agent with operational knowledge about Goldsky Edge, an EVM RPC proxy built on eRPC. It covers endpoint URL structures across chains like Ethereum, Base, or Arbitrum, alongside setup patterns for viem and ethers.js.

The reference details authentication options, RPS budget tiers per IP or secret, and x402 pay-per-request micropayments settled in USDC on Base. It also provides context for diagnosing JSON-RPC errors from -32005 to -32016 and auto-splitting large `eth_getLogs` queries.

Passing credentials via the URL query parameter risks leaking the `gs_edge_` secret into CDN and access logs. Production setups should supply the `X-ERPC-Secret-Token` header instead.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add goldsky-io/goldsky-agent --skill edge -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/edge/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/edge/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add goldsky-io/goldsky-agent --skill edge -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/edge/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add goldsky-io/goldsky-agent --skill edge -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/edge/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install goldsky-io/goldsky-agent edge
```

2. **Manually: put the files in place**
- File: `.github/skills/edge/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add goldsky-io/goldsky-agent --skill edge -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/goldsky-io/goldsky-agent --path skills/edge
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/edge/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add goldsky-io/goldsky-agent --skill edge -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/goldsky-io/goldsky-agent/tree/HEAD/skills/edge/SKILL.md

## When to use it
- configure EVM clients in viem or ethers.js using Goldsky Edge
- select rate limit budgets per IP or total requests per second
- troubleshoot RPC errors between -32005 and -32016
- set up x402 micropayments on Base for keyless requests

## Example prompts
- Set up a viem transport using Goldsky Edge for Base mainnet
- Help me pick a rate limit tier for 1,000 requests per minute with per-IP limits
- Why is my eth_getLogs call failing with error -32005?

# Goldsky Edge (RPC Endpoints)

Goldsky Edge is a managed, high-performance RPC endpoint service for EVM blockchains, built on eRPC — an open-source fault-tolerant EVM RPC proxy. It provides globally-distributed, low-latency RPC access with intelligent routing, caching, failover, and built-in observability.

## What Edge Does

Edge sits between your application and blockchain RPC providers. It adds:

- **Performance**: Global edge infrastructure across 8+ regions, sub-100ms latency, tip-of-chain CDN caching
- **Resiliency**: Automatic failover across multiple providers for 99.9% uptime, hedged parallel requests
- **Data Integrity**: Cross-validates responses from multiple nodes, tracks block heights, enforces consensus checks
- **Cost Control**: Request deduplication, intelligent routing, configurable rate limiting
- **Indexing Optimizations**: Auto-splits large `eth_getLogs` requests, routes historical queries to archive nodes

## Quickstart

### Endpoint Format

```
https://edge.goldsky.com/standard/evm/{chainId}?secret=YOUR_SECRET
```

Replace `{chainId}` with the chain ID (e.g., `1` for Ethereum, `8453` for Base, `42161` for Arbitrum).

### Authentication

Three options:
- **Header (recommended)**: `X-ERPC-Secret-Token: YOUR_SECRET` — keeps the secret out of URLs, which are commonly logged by proxies, CDNs, and server access logs.
- **Query parameter**: `?secret=YOUR_SECRET` — convenient for quick tests, but the secret leaks into any log that records the full URL. Prefer the header for production traffic. The examples below use the query param for brevity.
- **x402 (pay-per-request)**: Clients without a secret receive an HTTP 402 response with payment requirements. An x402-compatible client signs a USDC payment and retries; Edge settles via a facilitator before forwarding the request upstream. Payment is settled on **Base** (chain `8453`) in USDC. Pricing is `$0.000005` per request (same as the standard `$5 per million` rate). See https://www.x402.org/ for the protocol spec.

### Example (curl)

```bash
curl -s "https://edge.goldsky.com/standard/evm/1?secret=YOUR_SECRET" \
  -X POST \
  -H "Content-Type: application/json" \
  -d '{"jsonrpc":"2.0","method":"eth_blockNumber","params":[],"id":1}'
```

### Example (viem)

```typescript
import { createPublicClient, http } from "viem";
import { mainnet } from "viem/chains";

const client = createPublicClient({
  chain: mainnet,
  transport: http("https://edge.goldsky.com/standard/evm/1?secret=YOUR_SECRET"),
});
```
