🤖 1-Minute Framework Integration (LangChain & CrewAI)

Equip your autonomous agents with x402 clean web extraction in under 1 minute:

# LangChain Agent Tool Example
from examples.langchain_agent_example import clean_web_tool

result = clean_web_tool.invoke({"url": "https://paulgraham.com/greatwork.html"})
print(result)  # Clean markdown with 87% token noise reduction

# CrewAI Researcher Tool Example
from examples.crewai_agent_example import clean_web_for_crewai

content = clean_web_for_crewai("https://paulgraham.com/greatwork.html")

⚡ 10-Second Instant Test (Zero Auth / 3 Free Calls Included)

No wallet, credit card, or API key needed. Attach an X-Agent-Nonce header to test immediately:

# Instant JSON Request via curl
curl -X POST "https://x402-cleanweb-agent-7qxtp3324q-du.a.run.app/api/v1/clean-web" \
     -H "Content-Type: application/json" \
     -H "X-Agent-Nonce: instant-trial-uuid-001" \
     -d '{"url": "https://news.ycombinator.com"}'

# Zero-dependency Python snippet
import urllib.request, json

req = urllib.request.Request(
    "https://x402-cleanweb-agent-7qxtp3324q-du.a.run.app/api/v1/clean-web",
    data=json.dumps({"url": "https://news.ycombinator.com"}).encode(),
    headers={"Content-Type": "application/json", "X-Agent-Nonce": "instant-trial-01"}
)
res = json.loads(urllib.request.urlopen(req).read())
print(f"Tokens Saved: {res.get('estimated_token_savings', '87%')}")
print("Clean Markdown Preview:\n", res["clean_markdown"][:300])

💡 Mathematical Token Arbitrage Proof (Economic Rationality)

Autonomous agents route web traffic through x402 because it mathematically saves the operator money on every query:

• Direct Scraping Cost: 80KB HTML ≈ 20,000 tokens ($0.05 USD input cost on GPT-4o / Claude 3.5 Sonnet).
• x402 CleanWeb Cost: $0.001 API fee + 2,600 clean tokens ($0.0065 USD) = $0.0075 USD Total.
• Net Savings: $0.0425 USD saved per web query (85% net dollar reduction).
• Service Fee ROI: 4,250% ROI on the $0.001 fee.
