Overview

https://minia2a.uk answered on 2026-09-13 (page title: "Discover 1,600+ Verified Agent APIs — minia2a.uk"). Source is public at minia2auk/minia2a-mcp (MIT, 1★); created 2026-09-03, last pushed 2026-09-11. Documentation at https://minia2a.uk/guide answered on 2026-09-13. An MCP initialize handshake against https://minia2a.uk/mcp completed on 2026-09-13 and listed 1675 tools. One unpaid request to https://minia2a.uk/x402/token-security answered HTTP 402 with a payment payload we could parse (network eip155:8453, asset 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913). No payment was sent: a 402 says the endpoint asked for money in a readable shape, not that paying works or that the seller delivers. The host serves an x402 capability manifest at /.well-known/x402. The project's own materials describe balances held by the service as not withdrawable — money paid in is spendable through the service rather than returnable to a wallet. Read the current terms before funding an account. Listed from a maintainer submission; every field is self-reported except the checks above, which Sato Hub ran itself on 2026-09-13.

Answers a handshake: yes · 2026-10-28
Answers a call: yes — get_stats returned in 1957 ms

Live probe verifies the interface responds — not what the tools do, their safety, or their output quality. The call is one read-only tool named by this server's own list (list_/get_/search_, no mutating verb anywhere in the name, no required arguments and none that look like a key, an address or an amount), asked once a day with no arguments. Not asked is not a failure.

Observed record — 45 daily checks since 2026-09-14

95.6%of 45 checks since 2026-09-14 succeeded

Currently responding for 12 days

Succeeded: 43
Failed: 2
Their error: 0
Unattributed: 2

State changed on 2026-09-21 (responding → unreachable from our probe), 2026-09-22 (unreachable from our probe → responding), 2026-10-16 (responding → unreachable from our probe), 2026-10-17 (unreachable from our probe → responding).

This is the share of our daily checks that succeeded — not an availability guarantee. A check can fail because the host was down, because our runner timed out, or because the network in between dropped it, and only the first of those is a fact about this project. Failures are split by what we can attribute; anything we cannot attribute is counted, not hidden.

A gap is a day we have no attributable observation — never a zero. Thirty points is the whole shape the free layer carries; the daily rows behind it stay in the snapshot series.

Recorded from our own daily tools/list handshake. A shrinking toolset is a real signal for an agent choosing a server; a gap in the series means the probe did not succeed that day, not that the tools disappeared.
