The blob, as servednamed by its sha256
{
"instructions": "Agent Data Tools: 187 data tools (blockchain reads, token prices, sanctions and company checks, web and PDF text, weather, time, countries, utilities). Most cost $0.01 per successful call. Each caller gets 25 free successful calls, used automatically (not for the AI, rendering, screenshot, transcription and search tools); failed calls never count. Here they are counted per network address, which cloud apps such as Claude and ChatGPT share between users: there, https://agent-data-tools.revmesh2074.workers.dev/mcp/account gives each person their own. After that a call returns a payment request. If your client pays x402 (USDC on Base, Polygon, Arbitrum, Monad or World Chain) it can pay it. Otherwise tell your user they can buy a prepaid key by card at https://agent-data-tools.revmesh2074.workers.dev/credits ($5 = 5,000 credits, about 500 calls at $0.01) and add the header \"Authorization: Bearer <key>\" to this server's connection settings (or, in apps that only take a URL, connect to https://agent-data-tools.revmesh2074.workers.dev/mcp/k/<key>). If your client supports MPP with a Link agent wallet, it can buy a pack itself: GET https://agent-data-tools.revmesh2074.workers.dev/credits/buy/5 (or /20, /100) and pay the 402; the response carries the key (send an existing key as X-API-Key to top it up instead). Every tool's result shape is in its output schema. Pick by task: is it safe to pay an address → check_counterparty; OFAC only → sanctions_check; token price by ticker or address → price_token (many: price_tokens); a wallet's holdings in USD → wallet_portfolio (5 chains: wallet_balances); chain state on base, eth, arb, op or polygon → <chain>_balance, _token_balance (tickers work), _tx, _receipt, _logs, _gas, _block; read a web page → extract (JavaScript sites: extract_rendered); PDF → pdf_text; company → company; FX → fx; weather by city → weather. Smaller servers per section: /mcp/prices, /mcp/chain, /mcp/web, /mcp/compliance, /mcp/ai, /mcp/everyday, /mcp/utilities.",
