However sometimes fetch calls are blocked by the receiving server for using particular IP addresses. Additionally, network blips or unreliable web services may lead to failures if not handled properly.\n\nThe Val Town standard library contains an alternative version, [`std/fetch`](https://www.val.town/v/std/fetch), that wraps the JavaScript Fetch API to provide additional functionality. The fetch function from [`std/fetch`](https://www.val.town/v/std/fetch) reroutes requests using a proxy vendor so that requests obtain different IP addresses. It also automatically retries failed requests several times. Note that using [`std/fetch`](https://www.val.town/v/std/fetch) will be significantly slower than directly calling the Javascript Fetch API due to extra network hops.\n\n## Usage\n\nAfter importing [`std/fetch`](https://www.val.town/v/std/fetch), the fetch method is used with the same signature as the Javascript Fetch API.\n\n```ts title=\"Example\" val\nimport { fetch } from \"https://esm.town/v/std/fetch\";\n\nlet result = await fetch(\"https://api64.ipify.org?format=json\");\nlet json = await result.json();\nconsole.log(json.ip);\n```\n\nIf you run the above code multiple times, you'll see that it returns different IP addresses, because [`std/fetch`](https://www.val.town/v/std/fetch) uses proxies so that each request is made from a different IP address.\n\n\n[📝 Edit docs](https://github.com/val-town/val-town-docs/edit/main/src/content/docs/std/fetch.md)","# std/fetch — Proxied Fetch\n\nDrop-in replacement for JavaScript `fetch()` that routes requests through rotating proxy IPs via [ScraperAPI](https://www.scraperapi.com/).\n\nEach request gets a different IP address, useful for scraping and accessing content that blocks datacenter IPs.\n\n## Usage\n\n```ts\nimport { fetch } from \"https://esm.town/v/std/fetch/main.ts\";\n\nconst res = await fetch(\"https://httpbin.org/ip\");\nconst json = await res.json();\nconsole.log(json.origin); // A different IP each time\n```\n\nSame signature as native `fetch()`.\n\n## How It Works\n\n```mermaid\nsequenceDiagram\n participant SDK as main.ts (SDK)\n participant Proxy as proxy.ts\n participant VT as Val Town API\n participant SA as ScraperAPI\n\n SDK->>Proxy: POST {url, method, headers, body} + Bearer token\n Proxy->>VT: verify token\n Proxy->>Proxy: check rate limit (100/min per user)\n Proxy->>SA: fetch via ScraperAPI\n SA-->>Proxy: response\n Proxy->>Proxy: log to SQLite\n Proxy-->>SDK: pass response through\n```\n\n## Files\n\n| File | Type | Purpose |\n|------|------|---------|\n| `main.ts` | script | SDK — exports `fetch()` |\n| `proxy.ts` | http | Auth, rate limit, proxy, log |\n| `database.ts` | script | SQLite logging + rate limiting |\n\n## Environment Variables\n\n| Key | Description |\n|-----|-------------|\n| `ScraperAPI_KEY` | [ScraperAPI](https://www.scraperapi.com/) API key |\n\n## Rate Limiting\n\n100 requests per minute per user.
