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.
Example use cases
Audit historical x402 endpoint reliability
“I need to audit the complete historical observation record for all x402 endpoints — can you pull the full archive with all the daily Merkle roots and their Bitcoin timestamps so I can verify the data hasn't been assembled retroactively?”
Cryptographic provenance check for compliance
“For our compliance report, I need proof that the x402 endpoint monitoring data existed on the dates it claims — fetch the full ChainVerdict Pulse archive with the chained Merkle roots and OpenTimestamps attestations.”
Bootstrap local x402 quality dataset
“I want to build a local dataset of x402 API health history from day one — grab the entire observation archive from ChainVerdict Pulse, including all the daily records and their chained Merkle proofs.”
Technical details
Endpoint
GEThttps://pulse.chainverdict.xyz/v1/archive/fullWhen to prefer
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.
Side effects
- 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
