Quick start (curl)

# 1) First call returns 402 with x402 envelope:
curl -i -X POST https://wallet-intel-meta-mcp.mtree.workers.dev/v1/wallet/dossier_summary \
  -H 'content-type: application/json' \
  -d '{"address":"0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045","chains":["ethereum","base"]}'

# 2) Settle the envelope (sign EXACT-scheme USDC payment on Base, payTo as advertised),
#    then retry with X-PAYMENT header. The response is the actual data.

Why this exists

EVM wallet intelligence today is fragmented across 7+ specialized data sources - each requires a separate integration, separate auth, separate billing. This service is the x402-native one-call door: agents settle a single payment and get all 7 axes back in parallel with per-axis source attribution. Fail-soft means you never lose the whole dossier because one axis timed out. Built for compliance triage, treasury risk dashboards, and MCP-aware agents that need a single composite signal instead of 7 round-trips.
