Shares a payout wallet with 21 other endpoints — its adoption is attributed from that shared wallet's traffic, not earned exclusively.

Agent-visibility check: does an AI crawler (GPTBot, ClaudeBot, PerplexityBot, OAI-SearchBot) actually see your site? BEST-RATE pack: 4 checks for $5 ($1.25/check). Same service, smallest entry $2 at https://402registry.com/buy/one. Ladder: 1/$2, 2/$3, 4/$5. All packs: https://402registry.com/.well-known/402registry.json. A passing check earns a dated badge and a registry listing. No account, no card, no human.

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

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 100% — how much probe evidence backs this score. A thin history is flagged, not hidden.

This payout wallet is shared: figures cover all 22 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.
