Biggest gains

  3. +6 Docs available as markdown. Serve every docs page as .md, or honour Accept: text/markdown.

Each change is ready to paste, filled in for instacart.com, with a command to check it worked. Or hand the whole list to your coding agent.

An OpenAPI spec is the contract agents and SDK generators build against. Without it they guess from prose.

Where: https://instacart.com/openapi.json, linked from llms.txt and the API reference
// Serve the spec your API framework already generates (FastAPI: /openapi.json is built in).
// Next.js: app/openapi.json/route.ts
import spec from "@/openapi/openapi.json";
export const GET = () => Response.json(spec, { headers: { "Access-Control-Allow-Origin": "*" } });

// Every operation needs: operationId, summary, description, request/response examples,
// and the auth scheme (components.securitySchemes) so agents know how to send the key.
