https://api402x.com/safe-authority-check

Shares a payout wallet with 18 other endpoints — its adoption is attributed from that shared wallet's traffic, not earned exclusively.

Cheap poll: has the spending authority over this Safe changed since you last looked? You pass the fingerprint this route gave you last time; it recomputes the current one and compares. Call it with no fingerprint to get a baseline. The fingerprint covers owners, threshold, guard, moduleGuard, the singleton implementation, and the whole module graph including the owners and threshold of modules that are themselves Safes -- a change one level down flips it, which a flat owner list would miss. It deliberately excludes the nonce, so ordinary transactions do not read as an authority change. Nothing is stored on our side: you hold the baseline, so there is no account and no subscription. No archive reads either, which is why this is cheap; when it reports changed, buy GET /safe-signer-drift for what changed and in which block. A truncated walk returns indeterminate, never unchanged. Required: chain_id and address. Optional: fingerprint.

Composite reliability — the weighted average of the dimensions below, on a 0–100 scale.
Availability
93

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
0

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 90% — how much probe evidence backs this score. A thin history is flagged, not hidden.

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 19 endpoints paid at it, since payments cannot be attributed to one of them. Only payments settled on chains and facilitators we index.

Linked by wallet — likely same operator

On-chain agent identity and the x402 endpoint that shares its settlement wallet.
