  • A EvoCrawl API key — get one free

​
Setup

supabase functions new evocrawl-search

supabase functions new evocrawl-interact
Set the secret: 
supabase secrets set EVOCRAWL_API_KEY=fc-YOUR-API-KEY

​
Search the web

Edit supabase/functions/evocrawl-search/index.ts: 
import Evocrawl from "npm:@mendable/evocrawl-js";

const evocrawl = new Evocrawl({
  apiKey: Deno.env.get("EVOCRAWL_API_KEY"),
});

Deno.serve(async (req) => {
  const { query } = await req.json();
  const results = await evocrawl.search(query, { limit: 5 });

  return new Response(JSON.stringify(results), {
    headers: { "Content-Type": "application/json" },
  });
});

​
Scrape a page

Edit supabase/functions/evocrawl-scrape/index.ts: 
import Evocrawl from "npm:@mendable/evocrawl-js";

const evocrawl = new Evocrawl({
  apiKey: Deno.env.get("EVOCRAWL_API_KEY"),
});

Deno.serve(async (req) => {
  const { url } = await req.json();
  const result = await evocrawl.scrape(url);

  return new Response(JSON.stringify(result), {
    headers: { "Content-Type": "application/json" },
  });
});

​
Interact with a page

Edit supabase/functions/evocrawl-interact/index.ts: 
import Evocrawl from "npm:@mendable/evocrawl-js";

const evocrawl = new Evocrawl({
  apiKey: Deno.env.get("EVOCRAWL_API_KEY"),
});

Deno.serve(async (_req) => {
  const result = await evocrawl.scrape("https://www.amazon.com", {
    formats: ["markdown"],
  });
  const scrapeId = result.metadata?.scrapeId;

  await evocrawl.interact(scrapeId, {
    prompt: "Search for iPhone 16 Pro Max",
  });
  const response = await evocrawl.interact(scrapeId, {
    prompt: "Click on the first result and tell me the price",
  });
  console.log(response.output);

  await evocrawl.stopInteraction(scrapeId);

  return new Response(JSON.stringify({ output: response.output }), {
    headers: { "Content-Type": "application/json" },
  });
});
