How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, and we only credit what we can confirm. How we score →

Supply Chain Security87
  • No malware found by supply-chain analysis.Pass
  • Only part of the dependency tree could be resolved (113 of 117), so this covers what we could see, not the whole tree.Partial

Stability & Change Management23
  • Stability observed for 7 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial

Changelog

Every change we have recorded for this component, newest first. Security-relevant changes are always shown. ▲ marks a change for the better, ▼ a change for the worse; unmarked changes are neutral.

  • 3 Aug 26 +1

    No change was recorded against any check on this day. Stability & Change Management went from 20 to 23. That category is still filling its 30-day observation window: 6 days of observed history at the previous scan, 7 at this one. The score rises as the window fills, whether or not the server changes.

MCP tools — 10 exposed · ~1,057 tokens

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability.

Tool Tokens
alternatives ~124

Avoid paying unsafe x402 endpoints: ranked safe alternatives for the same capability.

NameTypeReqDescription
limitintegerMax alternatives to return (1..10, default 5).
taskClassstringService category hint (e.g. 'llm-completions', 'Inference'). Used as a fallback match key when `url` is unknown to the catalog, OR alone for category-only discovery.
urlstringURL flagged by preflight (or otherwise rejected). Looked up in the catalog to extract provider / domain / category / price band as match keys.

No output schema declared.

No examples provided.

buy_credits ~50

Prepaid credit pack for high-frequency x402 scam checks, preflight, and verified calls. Returns { creditId, balance, expiresAt }; use X-Credit-Id on subsequent preflight calls.

Input schema present but exposes no named parameters.

No output schema declared.

No examples provided.

catalog_decoys ~32

Searchable catalog of x402 endpoint risk signals; scam-like decoys, zombies, and price-traps flagged.

Input schema present but exposes no named parameters.

No output schema declared.

No examples provided.

credits_status ~107

Free, no payment required. Returns { creditId, balance, initialBalance, used, paidAmount, createdAt, expiresAt, expired, paymentTx, paymentNetwork }. UUID-only access — anyone holding the creditId can read state, same as decrement. 404 covers both 'malformed UUID' and 'no such credit' (same body so an attacker scraping random UUIDs can't tell them apart).

NameTypeReqDescription
creditIdstringyesThe creditId UUID returned by buy_credits.

No output schema declared.

No examples provided.

forensics ~51

Forensic x402 scam/risk report for a suspicious endpoint: probe history, signatures, decoy / price-trap patterns.

NameTypeReqDescription
urlstringyesThe full URL of the x402 endpoint to analyse.

No output schema declared.

No examples provided.

preflight ~66

Preflight x402 scam check: endpoint risk before you pay — decoy / zombie / price-trap / never-paid? Trust verdict in ~200ms before PAYMENT-SIGNATURE.

NameTypeReqDescription
urlstringyesThe full URL of the x402 endpoint the agent is about to pay.

No output schema declared.

No examples provided.

watch_status ~102

Returns the current state of a watch: active/expired, alerts remaining (out of 100 prepaid), last 10 alert deliveries with their delivery_status, and the last computed signal snapshot. Free — no payment required, secret-gated. The secret is the one returned by watch_subscribe.

NameTypeReqDescription
secretstringyesThe 64-char hex secret returned by watch_subscribe.
watchIdstringyesThe watchId UUID returned by watch_subscribe.

No output schema declared.

No examples provided.

watch_subscribe ~234

Monitor x402 endpoint risk; webhook on scam-like decoy / zombie / price-trap status changes. Returns watchId + secret; x402station.io posts HMAC-SHA256-signed JSON when subscribed signals fire or clear.

NameTypeReqDescription
signalsarraySignal names to alert on. Defaults to ['dead', 'zombie', 'decoy_price_extreme']. Full vocabulary covers preflight + forensics signals.
urlstringyesThe x402 endpoint URL to watch.
webhookUrlstringyesWhere x402station should POST alert payloads. Must be HTTPS, reachable from the public internet, and contain no userinfo (no user:pass@host). Loopback (127.0.0.1, ::1, localhost), private (RFC1918, l…

No output schema declared.

No examples provided.

watch_unsubscribe ~96

Deactivates the watch — no further alerts will be queued or delivered. The subscription is set is_active=false but the row + alert history is retained for audit. Free — no payment required, secret-gated. There is no refund for unused prepaid alerts.

NameTypeReqDescription
secretstringyesThe 64-char hex secret returned by watch_subscribe.
watchIdstringyesThe watchId UUID returned by watch_subscribe.

No output schema declared.

No examples provided.

whats_new ~195

Polling-friendly catalog diff. Body { since?, limit? } (default since=now-24h, limit=200, max 500). Returns added_endpoints[] (first_seen_at >= since AND is_active=true), removed_endpoints[] (flipped to is_active=false since), service-level counts, polls_in_window, and current active totals. Cheap ($0.001 USDC) so hourly polling stays under $1/month — perfect for aggregator agents that need a fresh delta without re-pulling the whole catalog. Internal ingest cron runs every 5 min, so polling more often than that returns identical data.

NameTypeReqDescription
limitintegerPer-list cap (1..500, default 200). Applied independently to added_endpoints and removed_endpoints.
sincestringISO 8601 timestamp. Default = now() - 24h. Cannot be older than 30 days or in the future.
