Overview

Zerion is an established wallet/portfolio product whose API exposes portfolio balances, DeFi positions, transaction history, PnL, NFTs, prices, and swap quotes across 40+ chains. It added x402 payment support on Base in 2026, letting agents pay roughly $0.01 USDC per request without an API key, and ships an MCP server and a JSON-first CLI for AI agents. Per-request pricing and chain counts are as reported by Zerion.

100%of 91 checks since 2026-07-26 succeeded

Currently responding for 91 days

Succeeded: 91
Failed: 0
Their error: 0
Unattributed: 0

This is the share of our daily checks that succeeded — not an availability guarantee. A check can fail because the host was down, because our runner timed out, or because the network in between dropped it, and only the first of those is a fact about this project. Failures are split by what we can attribute; anything we cannot attribute is counted, not hidden. 37 of these checks predate 2026-09-01, when the probe counted a bot-block (HTTP 403) as a failure and recorded no reason for any failure. Every one of them passed, so the rate covers them too.
