Common questions
Is GW8 Signal API safe?
It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.
What keys or codes does it need?
The registry does not list a required key, though some servers ask you to sign in on first use.
Does it run on my computer or in the cloud?
It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.
Is it still maintained?
The GitHub repo last changed –, and the latest version (1.2.0) reached the registry 20 days ago.
Which apps can use it?
Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.
What can I use instead?

GW8 Signal API
Pay-per-call crypto signals, token verdicts, flows and briefs. x402 USDC on Base. Signal only, not financial advice.
MCP endpoint: https://micro-saas-agent.onrender.com/mcp (Streamable HTTP, no sign-in)
claude mcp add --scope user --transport http gw8-signal-api-mcp https://micro-saas-agent.onrender.com/mcpAgent payment tools (x402, also MCP tools). Agent guide: /agents.md.
POST /api/pay/should-i-pay(should_i_pay, $0.02): spend policy + seller reputation in one call -> pay / dont_pay / ask_human, one signed receipt.POST /api/spend/check(check_spend_policy, $0.02): allow / deny / needs_approval for a proposed payment against your policy.POST /api/seller/reputation(check_seller_reputation, $0.01): 0-100 score and trusted / caution / avoid / unknown for an x402 seller wallet or endpoint, from public Base USDC history (buyers, wash share, age, concentration, 30d volume). Free data-source check:GET /api/seller/reputation/status. Data source: Alchemy Transfers API when the server hasALCHEMY_API_KEYset (free plan is enough), else keyless Blockscout.GET /api/seller/reputation/statusshows which source is active.
All three return Ed25519-signed receipts (free check: POST /api/receipt/verify). Value-capture and growth-lane screens are on /api/value and /api/growth (free /status on each). Day pass first for repeated calls: POST /api/pass/day. Full list: /llms.txt.
Which routes sold: GET /api/sales (add ?days=30 for a longer window). Free, no payment. Counts by route template, surface (x402, rapidapi, apify), and UTC day: paid (a new x402 settlement or a marketplace 2xx), pass (served with a day pass), quotes (HTTP 402), sample, and free. No buyer addresses or request data. The on-chain USDC transfer still shows only the amount; this is the route name that goes with it.
