Wallet and DeFi data provider offering portfolio, positions, transactions, PnL, and prices across many chains, with an agent-accessible API.
Last release Aug 28, 2026 · Last commit Aug 28, 2026 · ★ 59
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.

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. 49 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. Rates spanning that date mix two definitions. Since then: 100%.

A gap is a day we have no attributable observation — never a zero. Thirty points is the whole shape the free layer carries; the daily rows behind it stay in the snapshot series.
