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.
