Reading the signals

Evidence before rankings.

The Radar groups endpoint records by operating business, then publishes the underlying evidence instead of collapsing it into an opaque score. A listing can prove that a provider published a payable contract. Reported activity can show that calls occurred. Neither proves independent adoption, correct output, or safe execution.

DISCOVERY

What is being sold?

Description, method, URL, input schema, output contract, price, network, and merchant address.

ACTIVITY

What has been observed?

Thirty-day calls, endpoint-payer observations, and the latest recorded call supplied by the discovery feed.

BOUNDARY

What remains unverified?

Output quality, ownership, independent demand, settlement correctness, security, and delivery after payment.

OPEN API

Reuse the attributed index.

GET /api/x402/v1/businesses returns lightweight provider summaries, per-record EXVIV directory links, and canonical attribution. The raw resource feed remains available for endpoint-level work.

PAID QUERY · $0.05

Buy the aggregated answer.

GET /api/x402/v1/query returns nested endpoint contracts, activity evidence, payer observations, additional constraints, and explicit sorting after x402 settlement.

Pay for one answer, not another workspace.

Agents can inspect the exact inputs and $0.05 USDC price, receive an x402 challenge, and buy the filtered directory response without registering.
