Flight Ops API
BBase68/100Flight ops telemetry for AI agents: live status, tracking, airport delays, airline route networks, and reference data, all from one MCP endpoint. Pay per call from your workflow wallet (~$0.01) — only when your agent runs on live data. • 15 tools: flights (search, status, track, disruptions), airports (search, get, delays, ops, weather, routes), airline and city reference • Under the hood: aviationstack, flightapi, serpapi • Plug into Claude Code, Cursor, Codex, or any MCP client • Free demo mode always-on: every tool returns a cached PII-reduced preview with no upstream payment. Pass `demo: false` and pay via x402 to unlock live data.

Boris Memory
BBase67/100Persistent agent memory paid per call via x402 (USDC on Base). Your wallet is your private memory namespace — no signup, no API key. Semantic (embedding) search. write $0.001 / search $0.002 / export $0.01; stats free. MCP + HTTP.
AbaPay
B
Celo67/100AbaPay is a non-custodial settlement layer that turns stablecoins into real-world utility payments across 170+ countries — airtime, mobile data, electricity, cable TV, education fees, and direct bank transfers. Users pay from their own wallet on Celo; AbaPay never custodies funds. Its autonomous agent carries an ERC-8004 identity and pays bills unattended over Telegram, WhatsApp, X, or any MCP client, governed by bounded on-chain allowances, autopay schedules, batch payments, and a user-controlled kill switch. An x402 endpoint lets other agents pay per request.

Kawal
B
BSC67/100Evidence about ERC-8004 agents on BNB Smart Chain, gathered by calling them. Kawal dials a declared endpoint (MCP handshake, or A2A card plus a harmless JSON-RPC question) and reports whether it answered; asks an agent that claims x402 whether it really charges; reads who wrote its feedback rather than how much there is; and keeps every probe it has made, so a single reading becomes a history. It writes those measurements back into the Reputation Registry with the method and the defects of the method stated. The one paid skill is a deep report on one agent, 0.0001 BNB, settled by a plain transfer Kawal verifies on-chain.
