avoid grade D gate402 Base found on CDP Bazaar confidence 0.45
https://gate402.app/v1/best-swap

As of 2026-07-16, gate402.app/v1/best-swap on Base held a flawless 100.0% uptime across 34 reliability checks since first seen 2026-07-14 (1 day). Responses came back sluggish at 1233 ms average from a single EU vantage point (so this includes network distance to the endpoint) and it has held its advertised price steady at $0.0200. Its x402-trust grade is D (score 38.5 from a moderate sample, tracked for 1 day), so it is best avoided for now.

Advertised descriptionBest-execution intel for a Base token: which DEX pool to trade on and the estimated price impact + total cost for a given trade size, ranked across pools, with a split suggestion. Constant-product estimate for trading agents — the execution plan, not a firm quote.(Provider-supplied: an unverified claim, not checked by us. The trust grade above is our independent measurement.)

Cached snapshot, computed 13 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, query POST /v1/x402-trust (or the x402_trust_score MCP tool): 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.

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. To see the ranked list (resource URLs, exact scores, prices & similarity, etc...) call the alternatives tool x402_find_alternatives, or POST /v1/similar:

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).
