Shares a payout wallet with 37 other endpoints — its adoption is attributed from that shared wallet's traffic, not earned exclusively.

Prove what a web page said: signed, timestamped evidence of a page's content, with a screenshot. Returns the rendered text and its SHA-256 hash, a screenshot and its hash, response headers, the serving IP and TLS certificate, all signed so anyone can verify it later without trusting us. Use for web evidence, archiving terms of service or prices, compliance records, citation checks and disputes. $0.25 per page; verification is free.

Composite reliability — the weighted average of the dimensions below, on a 0–100 scale.
Availability
6

How often it was reachable when we probed it (weight 35%).

Latency
100

How quickly it answers when it is up — fast scores high (weight 20%).

Security
100

Whether it serves over working TLS / https (weight 15%).

Transparency
61

Whether the operator disclosed what it does — description, schema, identity (weight 15%).

Activity
2

Observed on-chain payments to this endpoint's wallet — transactions, volume, and distinct paying wallets over the last month (weight 15%; not yet measured when we have not seen its wallet settle).

Confidence 32% — how much probe evidence backs this score. A thin history is flagged, not hidden.

See the scoring methodology for exactly how each number is computed.

Operator context is derived from public RDAP/TLS records and unverified. Company and country are only available for endpoints that publish them (an OV/EV TLS certificate or a non-redacted domain record); most endpoints are CDN-fronted and disclose neither.

This payout wallet is shared: figures cover all 38 endpoints paid at it, since payments cannot be attributed to one of them. Only payments settled on chains and facilitators we index.
