Shares a payout wallet with 8 other endpoints — its adoption is attributed from that shared wallet's traffic, not earned exclusively.

Cancel a pending Payment Intent. Idempotent; 400 if already paid or refunded. Requires a Blackbird identity: link your agent wallet once at /connect, then call with x402 + SIWX (first call pays, later SIWX-signed calls are free); or pass a member JWT in the X-Blackbird-Token header.

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

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

Latency
not yet measured

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
36

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

Activity
1

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 36% — 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 9 endpoints paid at it, since payments cannot be attributed to one of them. Only payments settled on chains and facilitators we index.
