v1.2.0April 10, 2026

Cite-ready responses and rate-limit headers

AddedEvery /api/v1/salary/calculate and /api/v1/salary/projections response now includes a citation field ready to quote verbatim and an assumptions array explaining the methodology. Built for LLMs, agents, and reproducible research.
AddedX-RateLimit-Remaining, X-RateLimit-Limit, and X-RateLimit-Tier headers on every response. Use them for adaptive backoff in your client.
Changed/api/v1/salary/history free tier now returns a 4-quarter preview (Q3 2025 through Q2 2026) instead of a 403 response. Enough to audit methodology and quarterly deltas without an account.
AddedDedicated MCP manifest at /mcp-intelligence.json and standalone OpenAPI 3.1 spec at /openapi-intelligence.yaml. Drop directly into any LLM or agent.
