 So this API proposal makes the following changes:
 
 - The Delegated Content Routing API is defined using HTTP semantics, and can be implemented without introducing Reframe concepts nor IPLD
-- There is a clear distinction between the RPC protocol (HTTP) and the API (Delegated Content Routing)
+- There is a clear distinction between the [Kubo RPC](https://docs.ipfs.tech/reference/kubo/rpc/)  and the vendor-agnostic Routing V1 HTTP API (introduced in [IPIP-377](https://specs.ipfs.tech/ipips/ipip-0337/).
 - "Method names" and cache-relevant parameters are pushed into the URL path
 - Streaming support is removed, and default response size limits are added.
   - We will add streaming support in a subsequent IPIP, but we are trying to minimize the scope of this IPIP to what is immediately useful

 - Preference for human-readable request and response encoding, such as JSON format

 ##### Serialization Format
 
-IPNS records use [ProtocolBuffer serialisation format](../ipns/IPNS.md#record-serialization-format).
+IPNS records use [`application/vnd.ipfs.ipns-record` protobuf serialization format](https://specs.ipfs.tech/ipns/ipns-record/#record-serialization-format).
 This format is widely in use in IPNS over PubSub and DHT routing systems.
 One of the motivations of this document is to introduce simple to use HTTP APIs and ultimately reduce barrier for interaction across alternative systems.
 Further, interoperability across the existing and HTTP APIs is also desirable in order to reduce the barrier for adoption of the delegated HTTP APIs.
 
 The specification here maintains backwards compatibility in terms of record serialisation, with preference for human-readable formats such as JSON.
-To maximize interoperability with existing ecosystem, the canonical [IPNS record serialization format](../ipns/IPNS.md#record-serialization-format) (`0x0300`) can be requested with content type `application/vnd.ipfs.ipns-record`.

 ### Security
 
 All interaction over the APIs should use TLS to protect against third-party observation and tampering.
-Additionally, the IPNS records are signed by the publisher's identity and contain sequence number to avoid replay attacks.
+Additionally, the IPNS records must be [validated according to the rules stated in the IPNS spec](https://specs.ipfs.tech/ipns/ipns-record/#record-verification) before further processing.
 
-To avoid Denial of Service attack, maximum IPNS record size of `10 KiB` applies.
+To avoid Denial of Service attack, [maximum IPNS record size defined in IPNS spec](https://specs.ipfs.tech/ipns/ipns-record/#record-size-limit) applies.
 Implements are permitted to set a lower limit. If lower than the default maximum, the limit should be discoverable via `OPTIONS` request with header key `X-Ipns-Allow-Max-Size` with value specified as the number of bytes.
 
 Similarly, a client may check if a server supports ProtocolBuffer formatted records by checking the `X-Ipns-Allow-Protobuf` header key in response to `OPTIONS` request. If present the header value must be either `true` or `false` the absence of the header indicates that ProtocolBuffer formatted records are not supported.
