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 (6)
🟢x402_market_stats
Get measured statistics about the x402 ecosystem economy: total 30-day revenue across sampled resources, revenue concentration, revenue at a given rank, price distribution and payer concentration. Free. Use this to decide whether building or buying on x402 is worth it.
Input Schema
{
"type": "object",
"properties": {},
"additionalProperties": false
}🟢x402_check_endpoint(url)
Check whether an x402 endpoint is alive and emits a valid HTTP 402 payment challenge, before you pay it. Free liveness check. Returns reachability, status code and whether a valid challenge was found.
Input Schema
{
"type": "object",
"properties": {
"url": {
"type": "string",
"description": "Absolute https URL of the x402 resource to check."
}
},
"required": [
"url"
],
"additionalProperties": false
}⚪x402_gas_price(chain)
Current gas price and estimated simple-transfer cost for an EVM chain. Free preview route. Supports base, polygon, arbitrum, optimism, ethereum.
Input Schema
{
"type": "object",
"properties": {
"chain": {
"type": "string",
"enum": [
"base",
"polygon",
"arbitrum",
"optimism",
"ethereum"
],
"description": "Which chain to query. Defaults to base."
}
},
"additionalProperties": false
}⚪x402_facilitator_guide
Which x402 facilitators actually settle payments, measured by probing each with a real signed EIP-3009 payload. Tells you which are keyless, which need API keys, which are testnet-only and which are unreachable. Free. Use before choosing a facilitator.
Input Schema
{
"type": "object",
"properties": {},
"additionalProperties": false
}🟢x402_verified_merchants
List x402 merchants that have been VERIFIED to accept payment — each one actually paid with real USDC on Base, with the settlement transaction hash. This is different from a liveness probe: public censuses only check whether a 402 is emitted, not whether paying works. Use this to find endpoints that will actually serve you. Free.
Input Schema
{
"type": "object",
"properties": {},
"additionalProperties": false
}⚪x402_audit_merchant(url)
Full paid due-diligence audit of an x402 merchant: live probe, price-drift detection between advertised and actual challenge price, settlement history, unique buyer count, and on-chain verification that USDC actually reaches the payTo address. Returns PASS/CAUTION/AVOID with evidence. Costs $0.01 USDC via x402 — returns payment instructions if called without payment.

"type": "object",
"properties": {
"url": {
"type": "string",
