PulseFeed x402 Trust Oracle

https://pulsefeed.dev/a2a

Ask before you pay: PulseFeed tells an AI agent whether an x402 payment endpoint is safe to pay — liveness, anomaly scan (receiver-address changes between observations, catalog price vs. challenge price, invalid receivers, asset/network mismatch), on-chain receiver verification on Base, and an open 0-100 Trust Score. Built on a continuous independent audit of the x402 ecosystem (15508 endpoints probed of 25836 tracked, 17% of probed dead or invalid) plus a security audit of the MCP server ecosystem.

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
94

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

Security
94

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

Transparency
42

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

Activity
not yet measured

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 88% — 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.
