aid: lvlltd-com name: LVL LTD CO description: >- LVL LTD CO is a sole-operator product lab in Cleveland, Georgia (operator Joseph Lamar Taylor; trade name, LLC registration stated as pending) that runs lvlltd.com, an agent-native marketplace of 250 sealed AI-agent skill packs priced in USDC on Base (chain 8453) and settled over the x402 HTTP 402 protocol. Every skill has a free outline and sample; payment is proven by posting a Base transaction hash (or an EIP-3009 PAYMENT-SIGNATURE) back to /api/pay, and the public /api/proof ledger is the only success signal the operator will stand behind. The same catalog is exposed four ways: a 32-operation OpenAPI 3.1.0 REST contract at /openapi.json, a remote MCP server at /api/mcp that answers an anonymous tools/list with 59 tools, an Ed25519-JWS-signed A2A 1.0.0 agent card at /.well-known/agent-card.json with a JSON-RPC endpoint at /api/a2a, and a full agent map in /llms.txt. Optional AP2 spend mandates, ERC-8004 identity lookups, recurring catalog-access plans and a Coinbase CDP facilitator path sit on top of the one-time unlock model. url: https://raw.githubusercontent.com/api-evangelist/lvlltd-com/refs/heads/main/apis.yml image: https://lvlltd.com/og-imagine.jpg x-type: company x-source: harvest:a2a-registry x-tier: profiled x-tier-reason: enrichment pass 2026-09-19 (local-v3; was a2a-registry harvest stub) specificationVersion: '0.20' created: '2026-09-19' modified: '2026-09-19' tags: - Agents - Agentic Commerce - Agent Skills - A2A - MCP - x402 - Micropayments - Stablecoins - Marketplace - Agent-Native - United States tags_raw: - Agents - Agent commerce - Agent skills - A2A - MCP - x402 - Micropayments - Stablecoins - Marketplace - Agent-native - United States - Agent Commerce - agent-native apis: - aid: lvlltd-com:lvl-ltd-mcp-server name: LVL LTD MCP Server description: >- Remote Model Context Protocol server at https://lvlltd.com/api/mcp (alias /mcp; HTTP JSON-RPC, protocol version 2025-06-18, serverInfo lvlltd-skill-market 1.1.0). initialize and tools/list answer anonymously with 59 tools, each carrying a real inputSchema: catalog search and quoting, x402 purchase and unlock, proof verification, recurring plans and metering, the ESP and SCO protocol tools, an A2A bridge (a2a_discover, a2a_message_send, a2a_tasks_get, a2a_tasks_cancel), agent runtime helpers (KV memory, long-running tasks, event bus, decision receipts) and the Bankr x402 Cloud rail.
