Marlin docs

Overview

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.

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

Getting started

Pick a token. Paste a mint or choose from the live feed.
Read the spread. See holders, concentration and recent moves.
Set alerts. Get told when the picture changes.

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.

Scheduled probe runner that makes small paid test calls and stores the results with timestamps

Charts that answer one question each. Switch the window and the numbers update in place, with no dashboards to configure first.

Schema drift check that flags when an endpoint changes its response shape

Set the conditions you care about once. Marlin watches every block and tells you when one of them changes.
