Check what a paid x402 endpoint or MCP server delivered, from probes anyone can repeat.
Teppi is a remote MCP server published at api.teppi.xyz. It has been probed 7 times since 9/12/2026. It answered in 7 of them (100.0%), a near-uninterrupted record. Median response time is 1,848 ms, a delay an agent will notice. It offers a narrow, focused set of 4 tools. On the protocol side it still runs 2025-11-25 and has not moved to the newer spec.
Can an LLM agent pick the right tool here — names, descriptions and parameter clarity are assessed.

tools/list structure, inputSchema validity, and a functional smoke test — the components of the 0-100 score.
Tools the server advertised in the latest measurement — measured, not catalog-claimed.
search_capabilitiesSearch paid agent capabilities by task description. Returns the price, the input and output schemas, the networks each one settles on, and what has been verified about it. Sort by verified to put the ones with the most evidence behind them first. Use before paying an x402 endpoint you have not used.
querystringrequiredmax_usdstringnetworkstringlimitintegersortstringget_capabilityFull detail for one capability: schemas, pricing, networks, the seller behind it, and every observation recorded against it.
idstringrequiredplan_routeTurn a goal and a budget into an ordered list of paid endpoints that could reach it, with a cost estimate and what has been verified about each step. Moves no money and buys nothing: it returns the plan for you to run yourself.
goalstringrequiredbudget_usdstringrequiredmin_gradestringcheck_gradeReturn what has been verified about an x402 endpoint or its url: whether it answers, what it charges, and whether that price has moved. Answers unrated rather than guessing when the evidence is thin. Works for endpoints Teppi does not operate.
id_or_urlstringrequiredEach block is one measurement round. Green: working response. Amber: responded but the server was returning errors (5xx). Red: no response at all.
Each cell is one probe run. Faded cells are incomplete probes — one leg did not answer, so the era is inconclusive.
The two probe legs separately: modern server/discover and legacy initialize.
Derived by comparing consecutive probes — changes in era, protocol version, build and reachability.
