Summary

Sofya wraps four research operations into a single streamable HTTP endpoint: search returns full page content instead of snippets, fetch converts URLs into clean markdown including PDFs and DOCX files, extract uses AI to pull structured data from pages, and research runs multi-source synthesis with citations. Each operation costs between 1 and 25 credits depending on depth. The markdown output is designed for agent consumption, and the research endpoint breaks queries into sub-questions before synthesizing results. Reach for this when your agent needs more than search snippets or when you want document fetching, extraction, and synthesis through one API instead of chaining multiple tools.

Coal - Payments for AI agents

coal/coal-payments

# Coal Coal gives AI agents a real checkout. Discover merchants through the decentralized 0G Storage catalog, pay autonomously in USDC on Base via x402 (Coinbase) or OKX APP (v2 envelope), and download purchased products — all without a human in the loop. Receipts are anchored on 0G Chain, allowing any third party to independently verify payments without trusting Coal itself. The MCP server is fully multi-tenant: every user supplies their own wallet key through the `X-Coal-Agent-Key` header, meaning the server never stores long-lived private keys or custody secrets. Agents are gasless by default — Coal covers operator gas costs. --- ## MCP Tools (13) ### Discovery & Marketplace * `discover_merchants` Browse the marketplace as a Markdown product grid * `search_products` Search and filter by product name, price, or tags * `get_merchant_profile` Retrieve merchant metadata and payout addresses * `query_merchant_memory` Natural-language merchant Q&A powered by TEE-backed 0G Compute --- ### Payments & Checkout * `check_paywall` Check whether an address has already paid * `create_checkout` Create a Coal checkout session *(requires API key)* * `get_checkout_status` Retrieve checkout session state and payment status * `pay_merchant` Send USDC on Base using ERC-3009 gasless transfers --- ### Verification & Delivery * `verify_receipt` Verify the complete proof trail: 1.
