Check an x402 endpoint before your agent pays it: challenge validity and on-chain payer evidence.

Give your agent a pre-payment check for paid x402 endpoints. Evidence before you pay.
ProvenPaid checks an x402 endpoint before your agent relies on it: is its payment challenge valid, and do real wallets actually pay it on-chain, come back, and how concentrated are payments? This MCP server exposes that check as a tool. The first 10 checks are free, with no wallet and no setup. After that it pays automatically, about $0.01 in USDC on Base per check, from a wallet you control.
Use it once before relying on an unfamiliar endpoint, not before every call.
| Tool | Cost | What it does |
|---|---|---|
check_x402_endpoint(url) | first 10 free, then about $0.01 | Validates the endpoint's x402 challenge and reports public on-chain evidence for its receiving address: distinct payers, repeat-payer share, payer concentration, coverage. |
provenpaid_methodology() | free | How each signal is computed, what is not verified, and when a check is charged. |
provenpaid_status() | free | Free checks left, paying wallet address, network, price cap and paid checks left today. |
You are not charged when the URL is invalid or unsafe, is not an x402 endpoint, or offers no payment option in USDC on Base. Results are evidence, not a verdict: ProvenPaid does not verify service quality or that an endpoint controls its receiving address.
Requires Python 3.11+. With uv:
uvx provenpaid-mcp
or pip install provenpaid-mcp.
{
"mcpServers": { "provenpaid": { "command": "uvx", "args": ["provenpaid-mcp"] } } }
On first run it creates a local identity key (~/.provenpaid-mcp/identity.key, owner-only). The key holds no funds; it only lets ProvenPaid count your 10 free checks. Only checks that return evidence count.
Add a dedicated, low-balance wallet:
{
"mcpServers": { "provenpaid": { "command": "uvx", "args": ["provenpaid-mcp"], "env": { "PROVENPAID_WALLET_PRIVATE_KEY": "0x...", "PROVENPAID_DAILY_LIMIT": "20" } } } }
Guardrails enforced before anything is signed:
| Setting | Default | Meaning |
|---|---|---|
PROVENPAID_MAX_PRICE_USD | 0.01 | Refuse any check priced above this (hard ceiling 0.10). |
PROVENPAID_DAILY_LIMIT | 20 | Maximum paid checks per UTC day, persisted across restarts. |
PROVENPAID_NETWORK | eip155:8453 | Pay only on this network, only in its USDC. eip155:84532 for Base Sepolia testing. |
PROVENPAID_API_URL | https://api.provenpaid.com | Must be https. |
PROVENPAID_STATE_DIR | ~/.provenpaid-mcp | Where the daily counter is kept. |
The server calls GET https://api.provenpaid.com/v1/check?url=.... The API answers HTTP 402 with x402 payment requirements; the official x402 SDK signs a single-use USDC authorization within the guardrails above and retries. Settlement happens only when the check delivers evidence. Methodology: https://api.provenpaid.com/methodology
