Common questions

Is Iposignal safe?

It passed 3 of 3 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 (1.3.0) reached the registry 2 months 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?

IPOSignal — MCP server, A2A agent card, x402 API

Machine-readable IPO intelligence from iposignal.xyz: deal terms, SEC filings, AI research, proprietary market and social sentiment, and live valuation metrics for any US-listed company.

Three ways in, all against the same data:

A2A agent card

Served at both paths during the spec transition:

  • https://iposignal.xyz/.well-known/agent-card.json — current spec
  • https://iposignal.xyz/.well-known/agent.json — legacy (v0.2 and earlier)

Discovery manifest: https://iposignal.xyz/api/a2a

Six skills, one free (lookup_companies_with_financials), five paid via x402.


Paying with x402

Endpoints under /api/agent/* are machine-payable using the open x402 protocol. USDC on Base mainnet (eip155:8453).

  1. Call the endpoint. Unpaid requests return HTTP 402 with a PAYMENT-REQUIRED header describing price, asset, network and recipient.
  2. Your x402 client signs the payment and retries with a PAYMENT-SIGNATURE header.
  3. The payment is verified and settled on-chain, then the data returns with a PAYMENT-RESPONSE settlement header.
Prices

Live values are always in the agent card under payment.prices — read them there rather than hardcoding.

EndpointPrice
GET /api/agent/companies?q={query}free
