  3. +3 Free tier or test mode. Offer free credits or a sandbox so an agent can verify an integration before payment.

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

Where: https://vanta.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.
