# GenTech Labs — BlockRun Integration Patterns Real-world patterns from running BlockRun MCP in production across 32 cron jobs and daily agent operations. --- ## Getting Started ### Initial Wallet Setup ```bash # Set up BlockRun wallet (one-time) blockrun_wallet(action="setup") # → Follow the QR to fund the wallet with USDC ``` ### Budget Controls ```python # Set a global budget cap so spending never surprises you blockrun_wallet(action="budget", budget_action="set", budget_amount=10.0) # Spawn child agents with delegate budgets blockrun_wallet(action="delegate", agent_id="researcher", agent_limit=2.0) blockrun_wallet(action="delegate", agent_id="data-poller", agent_limit=0.50) ``` ### Check Balance ```python blockrun_wallet(action="status") # → Two wallets: Base + Solana. Active chain shown. Check before expensive runs. ``` --- ## Daily Usage Patterns ### Pattern 1: Regular Price Checks (FREE) Crypto, FX and commodity quotes cost **nothing** — `blockrun_price` is free for those categories (`stocks`/`usstock` quotes are not served since 2026-09-05 — the gateway 501s before payment; only the ticker catalog works). Use them liberally. (`blockrun_surf`, which used to charge $0.0085 for the same quote, was removed in 0.49.0 — the gateway 410s every Surf path since 2026-09-06.) ```python # Single price blockrun_price(action="price", category="crypto", symbol="BTC-USD") # Batch of prices blockrun_price(action="price", category="crypto", symbol="ETH-USD") blockrun_price(action="price", category="crypto", symbol="SOL-USD") # Free — discover available symbols blockrun_price(action="list", category="crypto", query="sol") ``` **Cost:** $0 — crypto/FX/commodity price *and* list calls are both free. `category:"stocks"` price/history currently return 501 (equity quotes withdrawn 2026-09-05, nothing charged); its `list` catalog is free. ### Pattern 2: Token Research Pipeline (~$0.018) Start with the free tools, then pay only for what they cannot answer. ```python # 1. Free — DEX liquidity + volume (free endpoint) blockrun_dex({ query: "SOL" }) # 2. FREE — CEX price (crypto category is free) blockrun_price(action="price", category="crypto", symbol="SOL-USD") # 3. $0.0060 each — Protocol TVL blockrun_defi({ path: "protocols" }) blockrun_defi({ path: "protocol/jupiter" }) # 4. $0.0060 — Chain TVL blockrun_defi({ path: "chains" }) ``` **Total: ~$0.018 per full token analysis** (2 free calls + 3 x $0.0060 DefiLlama). Replace CoinGecko/CMC tabs entirely. ### Pattern 3: Research + Synthesis (~$0.011 + chat) Use Exa (neural search) + BlockRun Chat (second opinion) for thorough research. ```python # 1. $0.0110 — Neural web search with Exa blockrun_exa({ path: "search", body: { query: "latest AI agent infrastructure developments 2026", numResults: 10, category: "research paper" }}) # 2. per-token — Get second opinion from GLM-5 (excellent for technical details) blockrun_chat({ mode: "glm", message: "Summarize the key trends..." }) ``` **Cost-conscious tip:** Use `mode: "free"` on `blockrun_chat` for zero-cost generation (NVIDIA models). ### Pattern 4: Agent-to-Agent Billing Use `blockrun_wallet` + `agent_id` for multi-agent cost tracking. ```python # Allocate budget per agent group blockrun_wallet(action="delegate", agent_id="research", agent_limit=2.0) blockrun_wallet(action="delegate", agent_id="content", agent_limit=1.0) # Pass agent_id on every call blockrun_defi({ path: "protocols", agent_id: "research" }) blockrun_search({ body: { query: "latest news", sources: ["web"] }, agent_id: "research" }) # Audit at end of day blockrun_wallet(action="report") ``` --- ## Multi-Tool Pipelines ### DeFi Intelligence Pipeline ```python # 1. TVL & protocol health ($0.0060) blockrun_defi({ path: "protocol/aave-v3" }) # 2. Yield pools ($0.0060) blockrun_defi({ path: "yields" }) # 3. Token price (FREE — crypto category) blockrun_price(action="price", category="crypto", symbol="AAVE-USD") # 4. DEX activity (free) blockrun_dex({ token: "0x7Fc66500c84A76Ad7e9c93437bFc5Ac33E2DDaE9" }) ``` ### Portfolio Health Check ```python # 1. Current holdings (free — local data or blockrun_rpc) blockrun_rpc({ network: "base", method: "eth_getBalance", params: ["0xabc...", "latest"] }) # 2. Token prices (FREE — crypto category) blockrun_price(action="price", category="crypto", symbol="ETH-USD") blockrun_price(action="price", category="crypto", symbol="USDC-USD") # 3. Prediction market positions ($0.0085) blockrun_markets({ path: "polymarket/positions" }) ``` ### Content Generation Pipeline ```python # 1. Research ($0.0110) blockrun_exa({ path: "search", body: { query: "agentic commerce trends", numResults: 5 }}) # 2. Image generation for post ($0.01675 cheapest to $0.106 quality) blockrun_image({ prompt: "AI agent futuristic dashboard with neon grids" }) # 3. Voiceover for video ($0.0535/1k chars) blockrun_speech({ input: "Your narration text here...", voice: "sarah" }) # 4. Music track ($0.1585) blockrun_music({ prompt: "upbeat synthwave background" }) # 5. Short video clip ($0.421) blockrun_video({ prompt: "animated data visualization", duration_seconds: 8 }) ``` --- ## Cost Optimization Strategies ### Tier Mapping | Call Type | Price | Frequency | |-----------|-------|-----------| | `blockrun_price` (list) | FREE | daily discovery | | `blockrun_dex` | FREE | unlimited | | `blockrun_rpc` | $0.0030 | on-chain reads (batch: $0.002/element + $0.001) | | `blockrun_wallet` (status/report) | FREE | before every session | | `blockrun_price` (quote) | **FREE** | crypto/FX/commodity; stocks quotes not served (501 since 2026-09-05) | | `blockrun_defi` | $0.0060 | protocol/chain analysis ($0.0020 for prices/*) | | `blockrun_chat` (free mode) | $0 | NVIDIA-backed chat | | `blockrun_chat` (glm mode) | per-token | Zhipu GLM-5 coding — billed on tokens used, not a flat rate | | `blockrun_exa` (search) | $0.0110 | deep research (`contents`: $0.002/URL + $0.001) | | `blockrun_speech` | $0.0535/1k chars | TTS | | `blockrun_image` | $0.01675–0.106 | image generation | | `blockrun_music` | $0.1585 | music tracks | | `blockrun_video` | $0.421+ | short video clips (per-second × duration) | | `blockrun_markets` | $0.0085 | prediction market data, wallet analytics (flat) | | `blockrun_modal` | $0.0020–$192 | remote sandbox execution — `timeout` drives the price, see the modal skill | | `blockrun_phone` | $0.0110–$5.001 | lookups; number buy/renew is $5.001 | ### Daily Budget Formula (GenTech's Setup) ```yaml # ~$0.30/day typical Daily budget: Free tools: unlimited (price quotes, dex, list, wallet status) Crypto data: ~$0.10 (markets, flat $0.0085; defi $0.0060; surf is retired and free) AI calls: ~$0.10 (chat free mode, occasional glm) Media: ~$0.10 (occasional image/speech) Total: ~$0.30/day ``` Set a $5/week budget cap and never hit it with typical usage. --- ## Error Handling Patterns ### 402 Payment Required ```python # When the wallet is FUNDED, x402 handles this automatically: the SDK # signs the payment challenge and retries — no action needed. # # When the wallet is EMPTY, the 402 / insufficient-balance surfaces to you. # Check status and fund FIRST — don't blindly retry the failing tool: blockrun_wallet(action="status") # then action="setup" / "deposit" ``` ### Insufficient Balance ```python # Before a batch of expensive calls: balance = blockrun_wallet(action="status") if float(balance["usdcBalance"]) < 0.50: blockrun_wallet(action="deposit") # → opens Coinbase Onramp link ``` ### Rate Limiting / Timeouts ```python # For async operations (video, music): # They auto-poll until complete. On a timeout READ THE ERROR: on the Base # wallet payment settles on completion, so a timeout is not charged and a # retry is safe; Solana music and every account-rail media job are billed # at submit, so the timed-out job IS charged, the error names it, and a # retry bills a second job. Check blockrun_wallet action:"report" first. ``` --- ## Caching Strategy BlockRun calls are cheap but not free. Cache results that don't change minute-to-minute: - **Token prices:** No need to cache aggressively — crypto/FX/commodity quotes via `blockrun_price` are FREE. - **Protocol TVL:** Cache for 1 hour (updates hourly) - **Wallet labels:** Cache for 24 hours (rarely change) - **On-chain SQL results:** Cache for 1 hour (most queries return the same answer) GenTech's approach: Don't bother caching prices (crypto/FX/commodity quotes are FREE). Cache TVL and wallet labels aggressively. --- ## Switching Chains ```python # Default is Base. Switch to Solana for Solana-native tools: blockrun_wallet(action="chain", chain="solana") # Switch back: blockrun_wallet(action="chain", chain="base") # Check which is active: blockrun_wallet(action="chain") ``` **Note:** Every paid media tool (image, video, music, speech, realface) pays on either chain. Base-only: `blockrun_modal`, `blockrun_defi`, `claude-*` chat with `thinking` (a plain claude-* call takes the compat path on Solana), and Polymarket funding. Solana works for price, wallet, dex, rpc, markets, etc. --- ## Reference - BlockRun MCP: https://github.com/BlockRunAI/blockrun-mcp - BlockRun Docs: https://blockrun.ai/docs - Models & Pricing: https://blockrun.ai/models - Community: https://t.me/blockrunAI _Contributed by GenTech Labs, from real production usage of BlockRun MCP._
