• blockrun_defiread-only

  DeFi fundamentals via DefiLlama — protocol TVL, chain TVL, yield pools (APY), token prices. Pays per call in USDC, no API key. Paths (GET only; price = base + the gateway's flat tx fee, $0.001 today — we reserve $0.002; the 402 header carries the exact charge): - protocols ($0.005 base) — all DeFi protocols ranked by TVL - protocol/{slug} ($0.005 base) — one protocol's TVL history + chain breakdown, e.g. protocol/aave-v3 - chains ($0.005 base) — TVL by chain - yields ($0.005 base) — yield pools with APY + TVL …

• blockrun_image

  Generate or edit images via BlockRun. Pays with USDC on the ACTIVE chain — Base or Solana (see blockrun_wallet) — no separate API keys needed. Actions: - generate (default): Create image from text prompt - edit: Transform an existing image using img2img Generation models (1024x1024 base price; larger sizes cost more on gpt-image-*): - openai/gpt-image-2 ($0.06–0.12) — flagship, reasoning-driven, multilingual on-image text + character consistency (default) - openai/gpt-image-2.5-sunburst ($0.28–0.56) — OpenAI's most capable image model, high-precision editing - openai/gpt-image-2.5-flare ($0.…

• blockrun_marketsread-only

  Prediction market + derivatives data via Predexon aggregator. Flat $0.0075 base per call (every endpoint) plus the gateway's network fee — $0.001 on Base today, none quoted on Solana; the 402 header carries the exact charge (we reserve $0.0095).

• blockrun_modalcan change or delete data

  Run isolated code in a BlockRun-hosted Modal sandbox — disposable remote container, optional GPU. Use when you need: a clean ephemeral environment, GPU access (T4/L4/A10G/A100/H100 — those five only), or a safer place for untrusted code. Prefer local tools for normal repo work. ⚠️ `timeout` IS THE BILLED LIFETIME — charged upfront in full, NEVER refunded. It is not an idle timeout: you pay for the time you ASK for, not the time you use, and terminating early refunds nothing. Ask for what you need, not a safe-looking ceiling. - timeout ≤ 300s → flat: $0.0120 CPU · $0.0520 T4 · $0.0820 L4 · $0…

• blockrun_modelsread-only

  List available AI models with pricing. Use to discover models and compare costs.

• blockrun_music

  Generate music tracks via BlockRun x402 (async, client-polled). Generates a full-length ~3 minute MP3 track. Takes 1-3 minutes to complete. The tool submits the job and, for slower tracks, polls until it is ready. On the Base wallet payment settles only when a finished track is returned — if the job fails you are not charged; if this client gives up while a paid request is still in flight the gateway may still settle, and the error text says so. On Solana and on the account rail the job is billed when the gateway ACCEPTS it, so a job that later fails or outlives the poll budget is still charg…

• blockrun_realface

  Enroll a real person's face as a BytePlus RealFace asset, then drive Seedance 2.0 video with it (blockrun_video real_face_asset_id). A RealFace asset (ta_xxxx) lets Seedance 2.0 / 2.0-fast / 2.0-mini generate video of a SPECIFIC real person — not a generic seed image. Only those three models: seedance-2.5 is numerically newer but does NOT accept ta_ assets, and seedance-1.5-pro never did. Enrollment is a multi-step flow because BytePlus requires a live phone liveness check (the real person nods + blinks on camera) before a face photo can be uploaded. Actions: - init: FREE. Create an asset gr…

  Raw JSON-RPC against 40+ blockchains — one endpoint, no node, no API key. $0.002 base per call plus the gateway's flat tx fee ($0.001 today; we reserve $0.002, so budget/confirm show $0.004 per single call).
