47620 Data — MCP server (multichain)

Give any MCP-capable AI agent (Claude, Cursor, Windsurf, OpenClaw, …) native access to 47620 pay-per-call data settled over x402 (HTTP 402) in USDC — non-custodial, no signup, no API key. 26 tools across four lines:

• Onchain data — multichain (Solana, Base, Polygon): health, balance, token, tx, gas, trending, contract.
• Crypto market data — price, OHLCV, RSI/EMA/SMA indicators, funding/open interest, order book.
• CPU utilities — decode JWT, convert units, generate QR, unix timestamps, SHA-256.
• Research & trust — live x402 ecosystem adoption stats, payee trust, MCP server trust checks.

Multichain. One endpoint serves Solana, Base and Polygon. Onchain tools take an explicit chain param (solana | base | polygon). The chain you pay on is independent of the chain you query — pay USDC on any of the three.

Remote (streamable HTTP): https://47620.xyz/mcp/multichain (also /mcp). Legacy solana_* tool names keep working as aliases.

Payment modes

• X402_WALLET_KEY — base58 secret key of a wallet that holds a little USDC + gas. The server signs the payment and retries automatically. Fully autonomous (best for agents).
• X402_PAY_URL — an HTTP payment broker: POST { url, challenge } → { header }. For hosted / MPC wallets where the key never touches the process.
• neither — the tool returns the 402 challenge plus a ready-to-run npx awal x402 pay "<url>" command, so the agent (or its x402-aware runtime) pays.

Each call is a standard x402 paid request. Funds go directly to the seller's wallet (non-custodial).
