Teppi
Check what a paid x402 endpoint or MCP server delivered, from probes anyone can repeat.
Should I use this
Quality & Safety
Based on automated analysis of tool definitions and protocol compliance.
Context Cost
This is the approximate number of tokens consumed each time the server's tools are loaded into a model's context. Higher counts reduce the attention available for other tasks.

Tools (5)
🟢search_capabilities(query, max_usd, network, limit, sort)
Search 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.
Input Schema
{
"type": "object",
"properties": {
"query": {
"type": "string",
"minLength": 2,
"maxLength": 500
},
"max_usd": {
"type": "string",
"pattern": "^\\d+\\.\\d{1,6}$"
},

"sort": {
"type": "string",

}
},
"required": [
"query"
],
"additionalProperties": false
}🟢get_capability(id)
Full detail for one capability: schemas, pricing, networks, the seller behind it, and every observation recorded against it.
Input Schema
{
"type": "object",
"properties": {
"id": {
"type": "string",
"pattern": "^cap_[0-9A-HJKMNP-TV-Z]{26}$"
}
},
"required": [
"id"
],
"additionalProperties": false
}🟢plan_route(goal, budget_usd, min_grade)
Turn a goal and a budget into an ordered list of paid endpoints that could reach it, with a cost estimate and what has been verified about each step. Moves no money and buys nothing: it returns the plan for you to run yourself.
Input Schema
{
"type": "object",
"properties": {
"goal": {
"type": "string",
"minLength": 4,
"maxLength": 500
},
"budget_usd": {
"type": "string",
"pattern": "^\\d+\\.\\d{1,6}$"
},
"min_grade": {
"type": "string",
"enum": [
"A",
"B",
"C",
"D",
"F"
]
}
},
"required": [
"goal",
"budget_usd"
],
"additionalProperties": false
}🟢check_grade(id_or_url, method, pay_to)
Return 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, and a url never seen is put in line for a free handshake, so ask again in an hour.

}
},
"required": [
"id_or_url"
],
"additionalProperties": false
}🟢check_exposure(dependencies)
Look up every paid endpoint your agents call in one go, added up by the address each one pays: which are unknown to the record, which took money and returned nothing, which list what they do not serve, and how much monthly spend sits on each. Unknown is reported as unknown, never as bad.
