https://x402-echo-service.onrender.com/echo

Shares a payout wallet with 16 other endpoints — its adoption is attributed from that shared wallet's traffic, not earned exclusively.

Echo service for x402 protocol research. POST a JSON body with a "message" string; the response returns the message, its SHA-256 digest and a server timestamp. Payment is live: $0.001 USDC on Base is verified and settled via the Coinbase CDP facilitator, so callers ARE charged. The response is computed before settlement, and the settlement tx hash is returned in the body and in PAYMENT-RESPONSE.

Composite reliability — the weighted average of the dimensions below, on a 0–100 scale.
Availability
0

How often it was reachable when we probed it (weight 35%).

Latency
not yet measured

How quickly it answers when it is up — fast scores high (weight 20%).

Security
100

Whether it serves over working TLS / https (weight 15%).

Transparency
36

Whether the operator disclosed what it does — description, schema, identity (weight 15%).

Activity
15

Observed on-chain payments to this endpoint's wallet — transactions, volume, and distinct paying wallets over the last month (weight 15%; not yet measured when we have not seen its wallet settle).

Confidence 16% — how much probe evidence backs this score. A thin history is flagged, not hidden.

This payout wallet is shared: figures cover all 17 endpoints paid at it, since payments cannot be attributed to one of them. Only payments settled on chains and facilitators we index.
