Blockchain API access via Alchemy. Use when an agent needs to query blockchain data (balances, token prices, NFT ownership, transfer history, transaction simulation, gas estimates) across Ethereum, Base, Arbitrum, BNB, Polygon, Solana, and more. Supports API key access ($ALCHEMY_API_KEY), x402 wallet-based pay-per-request (SIWE/SIWS + USDC), and MPP protocol (SIWE + Tempo/Stripe). Triggers on mentions of RPC, blockchain data, onchain queries, token balances, NFT metadata, portfolio data…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Alchemy: Blockchain Data Access for Agents Alchemy provides comprehensive blockchain API access across Ethereum, Base, Arbitrum, BNB, Polygon, Solana, and more. Three ways to access: - **API key**: Set `$ALCHEMY_API_KEY` and make requests directly. Full access to all products. Create a free key at [dashboard.alchemy.com](https://dashboard.alchemy.com/). - **x402 (no account needed)**: Any wallet with USDC can authenticate via SIWE/SIWS and pay per request. Supports EVM and Solana wallets. Install `@alchemy/x402` and `@x402/fetch`. - **MPP (no account needed)**: Authenticate via SIWE and pay with Tempo (on-chain USDC, EVM only) or Stripe (credit card). Install `mppx`. ## Access Method Selection (Required) Before the first network call, determine which access method to use: 1. **Is `ALCHEMY_API_KEY` set?** → Use the API Key path. Skip to [API Key Access](#api-key-access). 2. **No API key?** → Ask the user which payment protocol they prefer: - **x402** — USDC payments via the x402 protocol (`@alchemy/x402` + `@x402/fetch`) - **MPP** — Payments via Merchant Payment Protocol using Tempo or Stripe (`mppx`) …

How to install
mdr add bankrbot/skills/alchemy@sha256:adc855eeb2c4137dThe line at the top of this page pins the label v2.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
