agent402.tools/v1/metered/responses
As of 2026-09-15, agent402.tools/v1/metered/responses on Base held 95.2% uptime across 21 reliability checks since first seen 2026-08-28 (17 days), with only occasional misses. Responses came back sluggish at 879 ms average from a single EU vantage point (so this includes network distance to the endpoint) and its advertised price moved 1 time (now $0.0010). Its x402-trust grade is B (score 76.8 from a moderate sample, tracked for 17 days), so it currently looks safe to use.
The latest analysis recorded 2 warnings for this endpoint.
This page is a cached snapshot (computed 2 hours ago, refreshed at least every 24h): it tells you what the verdict is, not why. What each flag says, which wallet or network it concerns and the evidence behind it is the paid trust report, re-probed live at the moment you ask.
A wallet payment page opens first; approve the USDC payment and the full JSON report loads right in your browser. Agents use the x402_trust_score MCP tool or POST /v1/x402-trust directly. Want a taste first? Read a free full sample report.
OpenAI Responses API billed per request from what the call costs: the 402 quotes exact-BPE input (instructions + input items + tools) plus your max_output_tokens at the model's list price, times 1.15, never under $0.001; an upto (Permit2) or credits buyer settles actual usage under that quote. Point the OpenAI SDK's responses.create(), the OpenAI Agents SDK, or OpenAI Codex CLI's model_providers base_url at https://agent402.tools/v1/metered.(Provider-supplied: an unverified claim, not checked by us. The trust grade above is our independent measurement.)
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-scored 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:

- ✓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. - ✓Instant snapshot refresh:
Every paid call also re-writes this cached snapshot, so the page, badge and card update immediately instead of waiting for the 24h cycle. - ✓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 (viaPOST /v1/x402-history), up to 90 days back. - ✓The ranked better-scored alternatives:
The resource URLs, scores & prices we don't reveal above (viaPOST /v1/similar), if there are better alternatives available. - ✓Change & liveness alerts:
Get notified on payTo/price changes, spec regressions or downtime (viaPOST /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-mcpPrefer HTTP? Call POST /v1/x402-trust directly (pay-per-call over x402, from $0.005).
