# TokenGuard On-Chain Pulse Digest

> TokenGuard On-Chain Pulse Digest is a paid API for AI agents from eltociear-tokenguard.hf.space, paid per call via x402, $0.05/call, status unknown (last checked 2026-09-15).

Returns a packaged on-chain analytics report combining biggest protocol TVL shifts with dollar amounts, trending tokens, and a recent-exploit overlay that tags TVL movers with matching hacks.

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 tokenguard-on-chain-pulse-digest-2b0399f1 -d '<json body>'
```

Example prompt: Pull me a combined on-chain pulse report for Ethereum — show protocols with at least a 10% TVL shift today (top 10 per section) and flag any of those movers that got hit by a recent exploit.

## When to prefer this

Choose this endpoint when you need a pre-joined, analyst-ready on-chain report combining TVL momentum and exploit risk in one call — rather than querying TVL, trending tokens, and exploit feeds separately and joining them yourself. Ideal for daily DeFi briefings, risk dashboards, or agent workflows that need to flag hacked protocols alongside genuine TVL movers without multi-step data assembly.

## Known failure modes

- Invalid chain identifier returns empty or error response
- Extremely high min_shift_pct may return zero results if no protocols meet the threshold
- Rate limiting or upstream data source unavailability may cause stale or missing data
- Payment failure (x402) blocks the call before processing
- Limit values outside expected range may be clamped or cause validation errors

## How this service works

One-call on-chain analytics digest: biggest protocol TVL shifts (with $ amounts), trending tokens, and a recent-exploit overlay JOINED to the TVL movers (a bleeding protocol gets tagged with a matching hack). Packaged report, not raw side-by-side lists.

## Output

A structured digest report containing: (1) the biggest protocol TVL shifts with percentage changes and dollar amounts, (2) currently trending tokens, and (3) an exploit overlay that cross-references TVL movers with recent hacks — bleeding protocols are tagged with the matching hack event. All three sections are pre-joined into a single packaged response, not separate raw lists.
