Shares a payout wallet with 5 other endpoints — its adoption is attributed from that shared wallet's traffic, not earned exclusively.

Should I submit this Base transaction now, and at what fee? One call returns submit-or-wait, max fee per gas and priority fee in gwei (EIP-1559), and the estimated cost in USD for an ETH transfer, USDC ERC-20 transfer, or x402 settlement on Base mainnet. Live gas price and congestion from Base RPC blocks, no API key. For bots that queue transactions: call before every send.

Composite reliability — the weighted average of the dimensions below, on a 0–100 scale.
Availability
98

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
10

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.

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.

Payout address changed 2 times, last on 9/22/2026

  • 0x8A89…fF4e → 0x05e1…6357 (base) · 9/22/2026
  • 0xAB74…423D → 0x8A89…fF4e (base) · 9/2/2026

A changed payout address is worth a second look — it can be routine, but it is also how a hijacked listing redirects funds.

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.
