This one has been quiet for a while

Quiet is not dead — but it is worth knowing when it wakes up, or when someone else takes it over. We watch the repository and tell you either way.

verify

verify

Checks x402 protocol conformance for a target service URL: a live 402 probe (well-formed challenge, non-empty accepts, atomic-unit amounts) plus price coherence against the target's own well-known. PAID ($0.10 USDC via x402). This MCP server holds no wallet, so calling this tool returns the upstream payment requirements rather than a result — pay them with your own x402 client, or call the endpoint directly. A signed, permanently published attestation of the same check is available at /midas-ops/attest ($0.50). Does NOT measure output quality, uptime history, or on-chain transaction volume — see the returned scope_note.

verify_before_pay

The question to ask BEFORE paying any x402 service: does MIDAX have a signed conformance verdict for this URL? FREE, ONE call. Returns the verdict with its age and freshness if one exists in MIDAX's signed registry, plus the authenticity verdict when that feature ships (always present in the payload, null with a note until then). If nothing exists yet, says so plainly and returns the exact price and route for the next paid step -- never a vague 'contact us'. Reads MIDAX's own registry only: it never probes the target live, so it adds minimal latency to your payment decision.

market

get_market_verdict

Runs a paid MIDAX402 analysis tier. Payment is x402-native: called WITHOUT payment_signature it returns the HTTP 402 payment requirements (decoded + raw PAYMENT-REQUIRED header) for your x402-capable wallet to sign; call again WITH payment_signature (the signed payment proof, as sent in the PAYMENT-SIGNATURE header) to receive the full analysis. This server NEVER holds keys and never signs — your wallet does.

sample

get_sample

Free sample of MIDAX402's analysis: returns ONLY the calibrated verdict and confidence score for an x402-ecosystem question, plus pointers to the paid tiers that serve the full analysis. Rate-limited; the full analysis is the paid product.

tiers

list_tiers

Lists the paid analysis tiers with their CANONICAL prices, fetched live from https://midax402.com/.well-known/x402 (resource_details) — the same first-party source directories crawl, so it can never drift.

Midax402 — questions

Answers built from our own checks of this server.

What can Midax402 do?

It exposes 5 tools, read directly from the server on our last check. Among them: get_market_verdict, get_sample, list_tiers, verify, verify_before_pay. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

Is Midax402 working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 91 checks got a reply (100.0%), average response time 551 ms. The bar chart above shows every period we have measured.

Is Midax402 still maintained?

The linked repository no longer exists on GitHub — it was deleted or made private. We show this because it changes what you can expect: an unmaintained server may keep answering for months and then stop without warning.

How do I connect Midax402?

Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does Midax402 need an API key?

No. Midax402 completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 5 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is Midax402?

It answers our handshake in 551 ms on average, which is faster than 24% of all working MCP servers we measure. That is on the slow side — worth knowing if the tool sits inside an interactive loop. The comparison comes from our own checks across the whole registry, every 15 minutes.
