# TraceFast Ethereum Address Daily Activity

> TraceFast Ethereum Address Daily Activity is a paid API for AI agents from mpp.tracefast.xyz, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-12).

Returns a per-day breakdown of how many blocks changed an Ethereum address's account state and the type of change (balance, nonce, code, or creation) over a configurable time window.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability tracefast-ethereum-address-daily-activity-5d7ed88f
```

Example prompt: Show me the daily on-chain activity for Ethereum address 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045 over the last 90 days — how many blocks each day changed its balance, nonce, or code.

## When to prefer this

Use this endpoint when you need a historical, day-granularity view of how frequently and in what way an Ethereum address's account state changed — specifically the breakdown by change type (balance, nonce, code, creation). Prefer this over raw block explorers when you need structured time-series data ready for analysis or monitoring workflows. It is ideal for detecting activity patterns, inactivity gaps, or unexpected state changes over configurable windows up to 365 days.

## Known failure modes

- Invalid address format (not 0x-prefixed or not 40 hex chars) returns an error
- Unsupported period value (not 30d, 90d, or 365d) returns a validation error
- Address with no on-chain activity returns empty daily records
- Network or payment failure (x402 payment not completed) results in 402 response
- Rate limiting or quota exhaustion may return 429

## How this service works

TraceFast live Ethereum data: for each day in a window, how many blocks changed the address's own account state and which kind of change it was (balance, nonce, code, creation). Path address: The address, `0x`-prefixed, 40 hex characters, any case. Query period: `30d`, `90d` (default) or `365d`. Docs: https://docs.tracefast.xyz/api/address-daily-activity.md

## Output

A time-series of daily records for the queried Ethereum address, each containing the date, the count of blocks that modified the address's account state, and the category of change (balance adjustment, nonce increment, code update, or account creation). Data covers the requested period (30, 90, or 365 days) from live Ethereum chain state.
