fresh-feeds — trending/new/changed MCP servers + x402 change-data API

Search the continuously-maintained MCP server registry (deduped, quality-scored, refreshed every 30 min) by name/title/description. Free; returns up to 25 matching servers with score, status, remotes and packages. For the FULL corpus (~1500 servers) use get_mcp_registry_snapshot (paid, x402).

    "query": {
      "type": "string",
      "description": "case-insensitive substring matched against server name/title/description; omit for the top servers by quality score"
    },
    "limit": {
      "type": "integer",
      "description": "max results 1-25 (default 10)",
      "minimum": 1,

    }
  }
}

Top 10 MCP servers by quality score + trending (new arrivals / score risers) + snapshot freshness. Free.

Free preview-grade trust report for one registry MCP server: a transparent 0-100 grade from cached signals (registry status, endpoint presence, freshness). The full report with a LIVE endpoint reachability probe + component breakdown is paid (verify_mcp_server_report, x402).

List the x402 services discovery catalog's active edge, liveness-probed: know a service is up and correctly demanding payment before you pay it. Free; up to 25. For the full liveness-probed feed use get_x402_services_snapshot (paid, x402).

Freshness/health of both feeds (snapshot ages, counts, available change-baseline dates). Free.

Verify-before-you-pay: a read-only fraud/impersonation RISK assessment (0-100, higher = riskier) for an ERC-8004 agent on Base, cross-referencing its DECLARED identity (agent-card) against on-chain control (ownerOf). Flags owner-mismatch, registration-inconsistency, off-chain/unproven cards, dead endpoints, and orphaned identities. Free; from a maintained sample of the first agentIds. Look up by tokenId (agentId) OR by the counterparty wallet/payTo you're about to pay (address — 0x… or eip155:8453:0x…). Omit both to list the sample (riskiest first).

{
  "type": "object",
  "properties": {
    "agentId": {
      "type": "integer",
      "description": "ERC-8004 Identity tokenId on Base; omit to list the maintained sample",
      "minimum": 1
    },
    "address": {
      "type": "string",
      "description": "the wallet/payTo you're about to transact with (0x… or CAIP-10 eip155:8453:0x…); resolves to the matching agent(s)' risk in the sample"
    }
