PulseFeed — x402 Agent-Payment Security & Trust (open data)
Independent, daily-updated trust & safety data for the x402 agent-payment economy (HTTP 402 + stablecoins on Base) and the MCP server ecosystem — by PulseFeed.
AI agents increasingly pay for APIs autonomously over x402 and connect to MCP servers that can run code on install. But ~76% of listed x402 endpoints are dead or invalid, and among the live ones there are recurring scams. This dataset is the free, public slice of PulseFeed's continuous audit. Last updated: 2026-07-21T04:00:03+00:00.
The audit, incident feed and reports are free and open. Live pages: /incidents · /status · /reports. Machine feeds: /incidents.json · /incidents.rss. Full per-service cross-domain data feed (paid, x402): /data.
Files
| File | What |
|---|---|
incidents.csv / incidents.json |
Active security incidents in the x402 economy — receiver hijacks, bait-and-switch pricing, honeypots, unverified receivers, price gouging — each with an on-chain proof URL. |
ecosystem.json |
Ecosystem aggregates: totals & dead %, catalog-accuracy audit, risk distribution, receiver-stability & on-chain receiver-profile distributions, top providers. |
mcp_security.json |
MCP server security summary: how many audited servers run an install script, are abandoned, ship no repo, etc. |

Honesty note
Findings are stated as facts from the data, not accusations of intent. "bait-and-switch" = advertised price != amount actually charged; "unverified receiver" = payTo has no on-chain USDC history (a risk signal, not a conviction); "possible hijack" = receiver changed on an established baseline (could be a legitimate key rotation). By-design receiver rotation is excluded.
Why it's unique
The signals here (receiver-stability over time, payTo/price change history, on-chain receiver profiles) are longitudinal — derived from continuously re-probing endpoints and recording changes as they happen. This history cannot be reconstructed after the fact.
