avoid grade C x402 inference gateway Base found on CDP Bazaar delisted confidence 1.00
https://agent-production-1daa.up.railway.app/v1/embeddings

As of 2026-08-15, agent-production-1daa.up.railway.app/v1/embeddings on Base responded to 87.4% of 388 reliability checks over the past 30 days, often enough to use but with outages frequent enough to plan around. Responses came back sluggish at 1024 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 $0.0010. Its x402-trust grade is C (score 55.0 from a solid sample, tracked for 35 days), so it is best avoided for now. It is no longer listed in the x402 directory.

Advertised descriptionText embeddings API for AI agents: OpenAI-compatible /v1/embeddings paid per request in USDC on Base — no account or API key. Embed documents for RAG, semantic search, clustering, deduplication with text-embedding-3-small or text-embedding-3-large. Embeddings are deterministic, so repeated texts hit our cache and bill at 55% of provider price — re-embedding a corpus costs roughly half. Misses at cost + 4%, from $0.001/call. Standard OpenAI POST format.(Provider-supplied: an unverified claim, not checked by us. The trust grade above is our independent measurement.)

Cached snapshot, computed 68 hours ago. 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.

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).
