You Need	You Call	Pricing
Image generation	DALL-E	$0.04/image
Real-time X data	Grok + Live Search	$0.025/source
Second opinion	GPT-5.2	$1.75/M input, $14/M output
Cheaper processing	DeepSeek	$0.14/M input, $0.28/M output

How it works: BlockRun uses x402 micropayments to route your requests to OpenAI, xAI, Google, and other providers. No API keys needed - your wallet pays per token.

Budget Control (Optional)

If the user specifies a budget (e.g., "use at most $1"), track spending and stop when budget is reached:

from blockrun_llm import setup_agent_wallet

client = setup_agent_wallet()
budget = 1.0  # User's budget

# Before each call, check if within budget
spending = client.get_spending()
if spending['total_usd'] >= budget:
    print(f"Budget reached: ${spending['total_usd']:.4f} spent")
    # Stop making calls
else:
    response = client.chat("openai/gpt-5.2", "Hello!")

# At the end, report spending
spending = client.get_spending()
print(f"💰 Total spent: ${spending['total_usd']:.4f} across {spending['calls']} calls")

When to Use

Trigger	Your Action
User explicitly requests ("blockrun second opinion with GPT on...", "use grok to check...", "generate image with dall-e")	Execute via BlockRun
User needs something you can't do (images, live X data)	Suggest BlockRun, wait for confirmation
You can handle the task fine	Do it yourself, don't mention BlockRun

Example User Prompts

Users will say things like:

User Says	What You Do
"blockrun generate an image of a sunset"	Call DALL-E via ImageClient
"use grok to check what's trending on X"	Call Grok with `search=True`
"blockrun GPT review this code"	Call GPT-5.2 via LLMClient
"what's the latest news about AI agents?"	Suggest Grok (you lack real-time data)
"generate a logo for my startup"	Suggest DALL-E (you can't generate images)
"blockrun check my balance"	Show wallet balance via `get_balance()`
"blockrun deepseek summarize this file"	Call DeepSeek for cost savings

Wallet & Balance

Use setup_agent_wallet() to auto-create a wallet and get a client. This shows the QR code and welcome message on first use.

Initialize client (always start with this):

from blockrun_llm import setup_agent_wallet

client = setup_agent_wallet()  # Auto-creates wallet, shows QR if new

Check balance (when user asks "show balance", "check wallet", etc.):

balance = client.get_balance()  # On-chain USDC balance
print(f"Balance: ${balance:.2f} USDC")
print(f"Wallet: {client.get_wallet_address()}")

Show QR code for funding:

from blockrun_llm import generate_wallet_qr_ascii, get_wallet_address

# ASCII QR for terminal display
print(generate_wallet_qr_ascii(get_wallet_address()))

SDK Usage

Prerequisite: Install the SDK with pip install blockrun-llm

Basic Chat

from blockrun_llm import setup_agent_wallet

client = setup_agent_wallet()  # Auto-creates wallet if needed
response = client.chat("openai/gpt-5.2", "What is 2+2?")
print(response)

# Check spending
spending = client.get_spending()
print(f"Spent ${spending['total_usd']:.4f}")

Real-time X/Twitter Search (xAI Live Search)

IMPORTANT: For real-time X/Twitter data, you MUST enable Live Search with search=True or search_parameters.

from blockrun_llm import setup_agent_wallet

client = setup_agent_wallet()

# Simple: Enable live search with search=True
response = client.chat(
    "xai/grok-3",
    "What are the latest posts from @blockrunai on X?",
    search=True  # Enables real-time X/Twitter search
)
print(response)

Advanced X Search with Filters

from blockrun_llm import setup_agent_wallet

client = setup_agent_wallet()

response = client.chat(
    "xai/grok-3",
    "Analyze @blockrunai's recent content and engagement",
    search_parameters={
        "mode": "on",
        "sources": [
            {
                "type": "x",
                "included_x_handles": ["blockrunai"],
                "post_favorite_count": 5
            }
        ],
        "max_search_results": 20,
        "return_citations": True
    }
)
print(response)

Image Generation

from blockrun_llm import ImageClient

client = ImageClient()
result = client.generate("A cute cat wearing a space helmet")
print(result.data[0].url)

xAI Live Search Reference

Live Search is xAI's real-time data API. Cost: $0.025 per source (default 10 sources = ~$0.26).

To reduce costs, set max_search_results to a lower value:

# Only use 5 sources (~$0.13)
response = client.chat("xai/grok-3", "What's trending?",
    search_parameters={"mode": "on", "max_search_results": 5})

Cost Reference

All LLM costs are per million tokens (M = 1,000,000 tokens).

Model	Input	Output
GPT-5.2	$1.75/M	$14.00/M
GPT-5-mini	$0.30/M	$1.20/M
Grok-3 (no search)	$3.00/M	$15.00/M
DeepSeek	$0.14/M	$0.28/M

Fixed Cost Actions
Grok Live Search	$0.025/source (default 10 = $0.25)
DALL-E image	$0.04/image
Nano Banana image	$0.01/image

Typical costs: A 500-word prompt (~750 tokens) to GPT-5.2 costs ~$0.001 input. A 1000-word response (~1500 tokens) costs ~$0.02 output.

Setup & Funding

Wallet location: $HOME/.blockrun/.session (e.g., /Users/username/.blockrun/.session)

First-time setup:

Wallet auto-creates when setup_agent_wallet() is called
Check wallet and balance:

from blockrun_llm import setup_agent_wallet
client = setup_agent_wallet()
print(f"Wallet: {client.get_wallet_address()}")
print(f"Balance: ${client.get_balance():.2f} USDC")

Fund wallet with $1-5 USDC on Base network

Show QR code for funding (ASCII for terminal):

from blockrun_llm import generate_wallet_qr_ascii, get_wallet_address
print(generate_wallet_qr_ascii(get_wallet_address()))

Troubleshooting

"Grok says it has no real-time access" → You forgot to enable Live Search. Add search=True:

response = client.chat("xai/grok-3", "What's trending?", search=True)

Module not found → Install the SDK: pip install blockrun-llm

Updates

pip install --upgrade blockrun-llm
