Early access

A live index of x402 endpoints with measured price, latency and uptime, so agents pick the cheapest one that actually works.

It measures instead of just listing. Every number comes from real paid probes, so builders can compare services without trusting the seller's own description.

Everything Marlin does, in one place.

Built for agent builders choosing paid data and compute sources, and endpoint owners who want to show reliability.

Public directory of x402 endpoints grouped by category, with price per call, median latency and 7-day success rate.

Every token in one sortable view. Marlin reads the chain directly, so a new launch shows up with its holder spread before most people open it.

Questions.

Short answers. The docs have the rest.

What is Marlin?

A live index of x402 endpoints with measured price, latency and uptime, so agents pick the cheapest one that actually works. It measures instead of just listing. Every number comes from real paid probes, so builders can compare services without trusting the seller's own description.

What works today?

Marlin is in development. Every feature is on the status list with what ships next, and the app opens in a sample workspace so you can see how it will work.

Do I need a wallet?

No. You can explore without one. Connecting a Solana wallet only shares your public address so Marlin can read your balances; it never asks you to sign a transaction.

Who is it for?

Agent builders choosing paid data and compute sources, and endpoint owners who want to show reliability.
