These patterns cover the most common ways to integrate TinyFish Web Agent into your application.

​
Simple Extraction

Use the synchronous endpoint for quick, one-off extractions where you need the result immediately. 
import { TinyFish, RunStatus } from "@tiny-fish/sdk";

const client = new TinyFish();

async function extractData(url: string, dataDescription: string) {
  const run = await client.agent.run({
    url,
    goal: `Extract ${dataDescription}. Return as JSON.`,
  });

  return run.status === RunStatus.COMPLETED ? run.result : null;
}

// Usage
async function main() {
  const products = await extractData(
    "https://example.com/products",
    "all product names and prices"
  );
  console.log(products);
}

main();

​
Batch Processing

For multiple URLs, use the async endpoint to submit all tasks at once, then poll for results. This avoids blocking while waiting for each task to complete. 
import { TinyFish, RunStatus } from "@tiny-fish/sdk";

const client = new TinyFish();

async function processBatch(tasks: { url: string; goal: string }[]) {
  // Submit all tasks
  const responses = await Promise.all(
    tasks.map((task) => client.agent.queue(task))
  );

  // Poll for completion
  const maxAttempts = 150; // 5 minutes at 2s intervals
  const results = await Promise.all(
    responses.map(async (r) => {
      if (r.error) {
        throw r.error;
      }
      for (let attempt = 0; attempt < maxAttempts; attempt++) {
        const run = await client.runs.get(r.run_id);
        if (
          run.status === RunStatus.COMPLETED ||
          run.status === RunStatus.FAILED ||
          run.status === RunStatus.CANCELLED
        ) {
          return run;
        }
        await new Promise((resolve) => setTimeout(resolve, 2000));
      }
      throw new Error(`Run ${r.run_id} timed out after ${maxAttempts} attempts`);
    })
  );

  return results;
}

// Usage
async function main() {
  const results = await processBatch([
    { url: "https://example.com/page1", goal: "Extract product info" },
    { url: "https://example.com/page2", goal: "Extract product info" },
  ]);
  console.log(results);
}

main();

​
Retry with Stealth Mode

Some sites block automated requests. Start with lite mode for speed, then automatically retry with stealth mode if you get blocked. 
import { TinyFish, RunStatus, BrowserProfile, ProxyCountryCode } from "@tiny-fish/sdk";

const client = new TinyFish();

async function extractWithFallback(url: string, goal: string) {
  // Try standard mode first
  let result = await client.agent.run({
    url,
    goal,
    browser_profile: BrowserProfile.LITE,
  });

  if (result.status === RunStatus.FAILED && result.error?.message.includes("blocked")) {
    // Retry with stealth mode
    result = await client.agent.run({
      url,
      goal,
      browser_profile: BrowserProfile.STEALTH,
      proxy_config: { enabled: true, country_code: ProxyCountryCode.US },
    });
  }

  return result;
}

​
Result Validation

A run with COMPLETED status means the agent finished, but the result may still describe a failure (e.g., the site showed a captcha or access-denied page). Always validate the result content. 
def is_real_success(result):
    """COMPLETED status is necessary but not sufficient."""
    if not result:
        return False
    result_str = str(result).lower()
    failure_signals = ["captcha", "blocked", "access denied", "could not", "unable to"]
    return not any(signal in result_str for signal in failure_signals)

# Usage
from tinyfish import TinyFish, RunStatus

client = TinyFish()
run = client.agent.run(
    url="https://example.com",
    goal="Extract pricing data. Return as JSON.",
)
if run.status == RunStatus.COMPLETED and is_real_success(run.result):
    print("Success:", run.result)
else:
    print("Needs retry or manual review")

​
Rate Limit Handling

TinyFish has concurrency limits based on your plan. The SDK automatically retries 429 and 5xx errors with exponential backoff (up to maxRetries attempts, default 2). 
import { TinyFish, RateLimitError } from "@tiny-fish/sdk";

// Adjust retry behavior via client options
const client = new TinyFish({
  maxRetries: 3,  // default is 2
});

async function main() {
  try {
    const run = await client.agent.run({
      url: "https://example.com",
      goal: "Extract data",
    });
    console.log(run.result);
  } catch (e) {
    if (e instanceof RateLimitError) {
      console.log("Rate limited after all retries exhausted");
    }
    throw e;
  }
}

main();

​
Cross-API Workflows

Chain multiple TinyFish APIs together for complex workflows.

​
Search + Fetch

Search for URLs, then fetch full content from the top results:
Python
from tinyfish import TinyFish

client = TinyFish()

# Step 1: Search for relevant pages
search_results = client.search.query("best python web frameworks 2026")

# Step 2: Fetch content from top 3 results
urls = [r.url for r in search_results.results[:3]]
fetched = client.fetch.get_contents(urls=urls, format="markdown")

for page in fetched.results:
    print(f"{page.title}: {page.text[:200]}...")

​
Search + Agent

Search for a URL, then extract structured data via the Agent API:
Python
from tinyfish import TinyFish, RunStatus

client = TinyFish()

# Step 1: Find a product page
search_results = client.search.query("scrapeme pokemon shop bulbasaur")
target_url = search_results.results[0].url

# Step 2: Extract structured data with the Agent
run = client.agent.run(
    url=target_url,
    goal="""Extract from this product page:
    - product_name, price (number), in_stock (boolean)
    Return as JSON.""",
)

if run.status == RunStatus.COMPLETED:
    print(run.result)
