Check an x402-paid API endpoint's trust score before paying it - live-probed, not self-reported.
Runs on your machine from its package; the steps are below.

Odel charges nothing per call. The publisher may charge for its own service.

This server isn't hosted — your MCP client launches it from a package registry. Use one of the commands below, or drop the config into your client (e.g. Claude Desktop).
Run
npx -y x402score-mcp
MCP client config
{
"mcpServers": {
"x402score": {
"command": "npx",
"args": [
"-y",
"x402score-mcp"
]
}
}
}Public client-side code for x402Score — free,
automated reputation scores for x402-paid API endpoints. The scoring backend itself is
closed-source (the exact weights, decay rate, and thresholds are deliberately unpublished,
to keep scores harder to game — see /docs).
This repo is just the two things a developer or agent needs to consume x402Score
programmatically.
sdk/ — x402score-sdk, published on npm. TypeScript client for the full
public API, plus signed-response verification. See sdk/README.md.mcp/ — x402score-mcp, an MCP server exposing four agent tools
(check_endpoint_score, search_leaderboard, get_calibration_report,
submit_endpoint), built on the SDK above. Not yet published to any MCP registry —
held until the on-chain payment signal's calibration gate closes (~2026-10-19, after
three weekly calibration cycles). See mcp/README.md.| Status | |

| SDK (npm) | Published — npm install x402score-sdk |
| MCP server | Built, tested, not yet published — see mcp/README.md for why |
Every API response can be verified two ways: a per-response signature proves a given
response really came from x402Score and wasn't altered in transit, and a daily
blockchain-anchored checkpoint proves the underlying historical data wasn't quietly
altered after the fact either. Full explanation at
/transparency.
