[DR-235] Add OpenAPI and AsyncAPI generation for docs - #21
Conversation
📝 WalkthroughWalkthroughThe PR adds a generator for RFQ OpenAPI and AsyncAPI specifications. It parses indexer OpenAPI data and protobuf sources, writes generated files under ChangesRFQ API specification generation
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🟡 Moderate · up to This change can publish stale or incomplete API specifications and currently advertises RFQ WebSocket routes that clients cannot reach, making the documentation unreliable for consumers. Merge should wait until the generation flow and published endpoints are corrected, or these bounded issues are explicitly accepted by the owner. Sequence Diagram(s)sequenceDiagram

generate-api-specs reads all_protos before the recipe rebuilds it. The generator parses all_protos/exchange/injective_rfq_rpc.proto, but generate refreshes all_protos from proto on the two lines after the generation step. The script therefore parses the previous tree, or, on a clean checkout where all_protos does not exist, prints a warning and skips AsyncAPI generation while make generate still succeeds. Every run then commits a specification that lags the current proto by one generation cycle.

Overview
Added make target to generate OpenAPi and AsyncAPI specs for TC Docs to serve from
/.well-known/api-catalogwith the goal of improving agent readiness.While there is an OpenAPI generation protoc plugin, the RFQ proto definitions lack grpc gateway http annotations, so the output from
protoc-gen-openapiv2isn't useable. AsyncAPI doesn't have a mature protoc plugin for bidirectional streaming RPCS, which is why both are ultimately generated via python script.Summary by CodeRabbit
