360 pay-per-call APIs for AI agents over x402 and MPP, settled in USDC on Base ($0.001-$0.25 a call, no account or API key). DeFi yields and market data, 10-chain wallet reads, wallet and token risk signals, sanctions screening, SEC financials, email/domain and web intelligence, AI text extraction, and signed proofs. Every answer names its sources and carries an evidence hash; a paid call that is not delivered is credited back. Built and run by UnyKorn LLC.
Create, send and track invoices from a conversation in Claude, ChatGPT or any MCP client that supports OAuth. Draft an invoice from one sentence or from last month's invoice for the same client, finalize it, email it to your client and send payment reminders for overdue ones. See revenue by month and by client, download PDFs and e-invoices (ZUGFeRD, XRechnung), and export DATEV packages for your tax advisor. Invoices follow the tax rules of 25 countries, including reverse charge and the small-business VAT exemption. New invoices are drafts, and nothing is emailed until you ask. Pay per invoice with no subscription: the first invoice is free.
Objective Trust ranks MCP endpoints before the caller pays them. Tools: set_objective (free), rank_tools_for_task (API key or $0.005 x402), record_outcome (free). Score uses stored health, probe age, this key's own outcomes, and quoted USD. Sponsored, featured, and click_count are excluded from the score. The caller calls the chosen mcp_url and pays that server. Connect at https://agentshare.dev/mcp/objective-trust.
