check_x402_endpoint | Before paying an unknown x402 endpoint, check whether it is safe: liveness, trust score (0-100), anomaly flags (receiver address changed between observations, catalog price vs. challenge price, invalid receiver, testnet listed as production, scheme outside the x402 spec), receiver stability and obse |
mcp_check_server | Before installing an MCP server or npm package, audit it: does it run an INSTALL SCRIPT (arbitrary code execution at `npm i`), is it abandoned, does it ship a repository and license, weekly downloads, provenance — with a safe/caution/avoid verdict. ~11% of audited MCP servers run install scripts. Fr |
mcp_drift_check | The rug pull check. `mcp_check_server` answers whether a package is safe TODAY; this answers what CHANGED after it was adopted: an install script added in a later version (arbitrary code on `npm i` that was not there at review time), package ownership swapped, repository removed, package unpublished |
mcp_security_report | State of MCP Security: how many audited MCP servers run an arbitrary install script, are abandoned, ship no repository or license — with day-over-day deltas and a sample of currently-flagged servers. From a daily audit of the MCP server catalog. Free. |
pulsefeed_products | List PulseFeed's paid products and how to pay via x402 (USDC on Base): deep trust check, endpoint track record, bulk trust dataset, full MCP drift series, the cross-domain Data API and on-chain token signals. Includes the client-side spend-cap gotcha for x402-fetch. |
x402_changes | What changed in the x402 ecosystem recently: services that stopped returning a valid challenge, receiver (payTo) changes, price changes, recoveries, newly-seen services. Derived from compounding time-series that cannot be reconstructed after the fact. Free. |
x402_data_sample | FREE sample of the PulseFeed Data API: top-10 live x402 services as FULL records (compounding payTo/price history, anomaly flags, on-chain receiver profile), top-10 MCP servers with full audit profile, and 3 live incidents. |
x402_ecosystem_stats | Live health of the whole x402 agent-payment ecosystem: tracked/alive/dead counts, catalog-accuracy audit (what share of listings called 'healthy' actually work), risk-level distribution, receiver stability and on-chain receiver profiles. Free. |
x402_incidents | Anomalies observed in live x402 endpoints by continuous independent measurement: receiver-address changes between observations, catalog price vs. challenge price mismatches, invalid receivers, testnet endpoints listed as production, payment schemes outside the x402 spec — EACH WITH AN ON-CHAIN REFER |
x402_leaderboard | Top x402 services ranked by the open PulseFeed Trust Score (0-100), with price and network — the most reliable live agent-payment endpoints right now. Free. |
x402_working_services | List x402 agent-payment services that are currently ALIVE and return a valid x402 challenge, ranked by PulseFeed Trust Score, plus ecosystem risk map. Use this to pick a service with a track record instead of paying an endpoint you have not checked. Free. |
