As of 2026-08-02, x402-mcp.onrender.com/swarm/products/d22bbf5f3c4b4666a6f80980c7bc7c50/purchase on Base held 98.1% uptime across 268 reliability checks since first seen 2026-07-21 (12 days), with only occasional misses. Responses came back slow at 1577 ms average from a single EU vantage point (so this includes network distance to the endpoint) and its advertised price moved 1 time (now $0.0500). Its x402-trust grade is B (score 72.9 from a solid sample, tracked for 12 days), so it currently looks safe to use.

Advertised descriptionBase gas price now, base fee and priority fee in gwei, block time, congestion and utilization trend, ETH price USD, and the USD cost to settle an ETH transfer, USDC ERC-20 transfer, or x402 payment on Base mainnet — one settle-now-or-wait verdict with rationale. Full market briefing; for the per-transaction submit/fee call see /base/tx-decision. GET, no inputs, no API key; computed live from Base RPC blocks.(Provider-supplied: an unverified claim, not checked by us. The trust grade above is our independent measurement.)

Cached snapshot, computed 7 hours ago (refreshed at least every 24h). This is the full-density trust score computed from every probe, same as the paid API... but it may be up to 24 hours old. For a guaranteed-current answer it re-probes the endpoint live at the moment you ask, adds a confidence band, the full component breakdown, structured risk flags and on-chain settlement proof:
Browser wallet payment, no code required — agents use POST /v1/x402-trust or the x402_trust_score MCP tool.

Latency is measured from a single EU vantage point; includes network round-trip distance to the endpoint; a geographically distant endpoint reads slower even when its server is fast, so it is only lightly weighted in the score.

↑ 10 better alternatives available

10 better-scored (some cheaper) endpoints serving a semantically similar purpose exist.

We don't reveal which ones here. The ranked list (resource URLs, exact scores, prices & similarity, etc...) is one paid call away — purchase it right here with a browser wallet, no code required:

A wallet payment page opens first; approve the USDC payment and the ranked JSON list loads right in your browser. Agents use the x402_find_alternatives MCP tool or POST /v1/similar directly.

This is the free cached snapshot. Here's what the paid API adds.
  • ✓
    Live probe at decision time:
    We re-check the endpoint the moment you ask (timestamped) and compute the score from all scores up until this moment, instead of this cached snapshot that may be up to 24h old.
  • ✓
    Confidence band, full component breakdown & structured risk flags:
    Exactly why the score is what it is, machine-readable.
  • ✓
    On-chain settlement proof:
    Real USDC volume & distinct-payer count for the payTo wallet: is anyone actually paying it?
  • ✓
    90-day raw history:
    Every listing/price/payTo change and probe result (via POST /v1/x402-history), up to 90 days back.
  • ✓
    The ranked better-scored alternatives:
    The resource URLs, scores & prices we don't reveal above (via POST /v1/similar), if there are better alternatives available.
  • ✓
    Change & liveness alerts:
    Get notified on payTo/price changes, spec regressions or downtime (via POST /v1/watch-endpoint-30d). Connect up to 10 Discord / Slack webhooks or poll regularly with bearer auth. Increases probe-density to every 5 minutes instead of the usual 30 for the watched endpoint.

... Simply give your agents the tools to do all of that for you, with a simple command
$npx -y x402-trust-mcp

Prefer HTTP? Call POST /v1/x402-trust directly (pay-per-call over x402, from $0.005).
