# TinyFish Web Agent

Requires: `TINYFISH_API_KEY` environment variable

## Pre-flight Check (REQUIRED)

Before making any API call, **always** run this first to verify the key is available:

```bash
[ -n "$TINYFISH_API_KEY" ] && echo "TINYFISH_API_KEY is set" || echo "TINYFISH_API_KEY is NOT set"
```

If the key is **not set**, you **MUST stop and ask the user** to add their API key. Do **NOT** fall back to other tools or approaches — the task requires TinyFish.

Tell the user:

> You need a TinyFish API key. Get one at: <https://agent.tinyfish.ai/api-keys>
>
> Then set it so the agent can use it:
>
> **Option 1 — Environment variable (works everywhere):**
> ```bash
> export TINYFISH_API_KEY="your-key-here"
> ```
>
> **Option 2 — Claude Code settings (Claude Code only):**
> Add to `~/.claude/settings.local.json`:
> ```json
> {
>   "env": {
>     "TINYFISH_API_KEY": "your-key-here"
>   }
> }
> ```

Do NOT proceed until the key is confirmed available.

## Best Practices

1. **Specify JSON format**: Always describe the exact structure you want returned
2. **Parallel calls**: When extracting from multiple independent sites, make separate parallel calls instead of combining into one prompt

## Basic Extract/Scrape

Extract data from a page. Specify the JSON structure you want:

```bash
curl -N -s -X POST "https://agent.tinyfish.ai/v1/automation/run-sse" \
  -H "X-API-Key: $TINYFISH_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "url": "https://example.com",
    "goal": "Extract product info as JSON: {\"name\": str, \"price\": str, \"in_stock\": bool}"
  }'
```

## Multiple Items

Extract lists of data with explicit structure:

```bash
curl -N -s -X POST "https://agent.tinyfish.ai/v1/automation/run-sse" \
  -H "X-API-Key: $TINYFISH_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "url": "https://example.com/products",
    "goal": "Extract all products as JSON array: [{\"name\": str, \"price\": str, \"url\": str}]"
  }'
```

## Stealth Mode

For bot-protected sites, add `"browser_profile": "stealth"` to the request body:

```bash
curl -N -s -X POST "https://agent.tinyfish.ai/v1/automation/run-sse" \
  -H "X-API-Key: $TINYFISH_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "url": "https://protected-site.com",
    "goal": "Extract product data as JSON: {\"name\": str, \"price\": str, \"description\": str}",
    "browser_profile": "stealth"
  }'
```

## Proxy

Route through a specific country by adding `"proxy_config"` to the body:

```bash
curl -N -s -X POST "https://agent.tinyfish.ai/v1/automation/run-sse" \
  -H "X-API-Key: $TINYFISH_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "url": "https://geo-restricted-site.com",
    "goal": "Extract pricing data as JSON: {\"item\": str, \"price\": str, \"currency\": str}",
    "browser_profile": "stealth",
    "proxy_config": {"enabled": true, "country_code": "US"}
  }'
```

## Output

The SSE stream returns `data: {...}` lines. The final result is the event where `type == "COMPLETE"` and `status == "COMPLETED"` — the extracted data is in the `resultJson` field. Claude reads the raw SSE output directly; no script-side parsing is needed.

## Parallel Extraction

When extracting from multiple independent sources, make separate parallel curl calls instead of combining into one prompt:

**Good** - Parallel calls:
```bash
# Compare pizza prices - run these simultaneously
curl -N -s -X POST "https://agent.tinyfish.ai/v1/automation/run-sse" \
  -H "X-API-Key: $TINYFISH_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "url": "https://pizzahut.com",
    "goal": "Extract pizza prices as JSON: [{\"name\": str, \"price\": str}]"
  }'

curl -N -s -X POST "https://agent.tinyfish.ai/v1/automation/run-sse" \
  -H "X-API-Key: $TINYFISH_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "url": "https://dominos.com",
    "goal": "Extract pizza prices as JSON: [{\"name\": str, \"price\": str}]"
  }'
```

**Bad** - Single combined call:
```bash
# Don't do this - less reliable and slower
curl -N -s -X POST "https://agent.tinyfish.ai/v1/automation/run-sse" \
  -H "X-API-Key: $TINYFISH_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "url": "https://pizzahut.com",
    "goal": "Extract prices from Pizza Hut and also go to Dominos..."
  }'
```

Each independent extraction task should be its own API call. This is faster (parallel execution) and more reliable.
