Refund Webhook
Refund Webhook is an asynchronous notification that reports creation or a later status change of a refund operation. It reports an event…
Remote Procedure Call (RPC)
Remote procedure call is a communication model that lets software invoke an operation on another process or machine as if calling a…
Request Deduplication
Request Deduplication identifies repeated requests and prevents or suppresses repeated processing according to a defined operation identity. It may use idempotency keys,…
Request Schema
A Request Schema defines the permitted structure, data types, formats, required fields, constraints, and nested objects of an API request. It can…
Request Signature
Request Signature is a cryptographic signature that covers selected components of an HTTP or API request so the receiver can verify integrity,…
Request Signing
Request signing uses a cryptographic key to create a verifiable signature over selected request data so a server can authenticate integrity and…
Request Timeout
A Request Timeout is the maximum time a client, proxy, server, or dependency waits for a request stage to complete before treating…
Response Schema
A Response Schema defines the structure, types, fields, constraints, and variants an API may return for a particular status or operation outcome.…
REST
REST is an architectural style for distributed systems that organizes interactions around resources, representations, uniform interfaces, and stateless communication. REST standardizes a…
Retry Policy
Retry Policy is the documented rules that determine whether, when, and how a failed or uncertain operation is attempted again. It is…

RPC Latency
RPC Latency is the elapsed time between sending a remote procedure request and receiving its response, measured at a defined observation point.…
RPC Monitoring
RPC Monitoring observes blockchain endpoint availability, latency, correctness, capacity, chain synchronization, and method behavior. It should detect both obvious outages and subtle…
RPC Rate Limit
An RPC Rate Limit restricts the request count, compute units, method cost, or concurrent workload allowed against a blockchain RPC service. Limits…
RPC Retry
RPC Retry is a repeated remote procedure call after a transient failure, timeout, throttling response, or unavailable endpoint. Retry behavior must account…
RPC Subscription
RPC Subscription is a persistent or long-lived RPC registration through which a client receives notifications when selected blockchain or node conditions change.…
RPC Timeout
