# ChainVerdict Pulse Full Archive

> ChainVerdict Pulse Full Archive is a paid API for AI agents from pulse.chainverdict.xyz, paid per call via x402, $0.5/call, status unknown (last checked 2026-09-15).

Returns the complete daily observation history of third-party x402 endpoints with Merkle-rooted, Bitcoin-timestamped chain for tamper-evident verification

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 chainverdict-pulse-full-archive-e817f04a
```

Example prompt: Pull the full tamper-evident archive of all x402 endpoint observations from ChainVerdict Pulse — I need the complete day-by-day history with Merkle roots and Bitcoin timestamp proofs going back to first observation.

## When to prefer this

Choose this endpoint when you need the complete, immutable, cryptographically verifiable history of x402 endpoint observations going back to first observation — particularly when tamper-evidence and provenance are required (e.g. compliance, audits, or dispute resolution). For recent data only, the free /v1/datasets/day/{day} endpoint covering the last 7 days is sufficient. For manifest/verification metadata only, use /v1/datasets/manifest. This full archive endpoint is the authoritative source when you need every day's Merkle root and Bitcoin timestamp proof in one call.

## Known failure modes

- Payment required (402) if the $0.50 USDC x402 payment is not included or fails
- Dataset may be large; client timeouts if the full archive has grown significantly
- Incomplete chain if the service is newly launched and only a few days of history exist
- Rate limiting or access denial if called too frequently without valid payment

## How this service works

The complete daily observation history of third-party x402 endpoints since first observation, with the Merkle root of each day. Each root is chained to the previous day and timestamped into Bitcoin via OpenTimestamps, so the archive can be verified as having existed on the stated dates rather than assembled later. The most recent 7 days are free at /v1/datasets/day/{day}; the manifest and verification method are free at /v1/datasets/manifest.

## Output

A paginated or bulk dataset containing every daily observation batch recorded for tracked x402 endpoints since first observation, organized by day. Each day entry includes the Merkle root of that day's observations, a chain link to the previous day's root, and an OpenTimestamps proof anchoring the root into the Bitcoin blockchain. This allows any recipient to independently verify the archive was not fabricated after the fact.
