Operations payable with x402 and their prices

GET
/.well-known/x402

Every operation a keyless caller can pay for once its budget is spent, with the networks, assets and atomic amounts it accepts, in the x402 discovery shape. Empty where x402 is switched off. Fields are camelCase because that is the x402 wire format.

Read the risk signals

Every risk signal a pair can carry, what it means, and which field lets you verify it yourself.

Liveness and upstream health GET

Reports `ok` when every upstream this API depends on is reachable, `degraded` otherwise. Cheap: it spends the smallest unit of a rate limit.
