- Appended VIN Decoder feasibility session to research/RESEARCH_LOG.md
- NHTSA vPIC: no rate limits, public domain, 1981-present coverage
- Competitor audit: 28,500+ combined RapidAPI subscribers across 4 listings
- Legal/ToS: 17 U.S.C. 105 public domain confirmed, no redistribution restrictions
- Decision: BUILD confirmed
- Added apis/vin-decoder/openapi.yaml with:
- GET /decode?vin={vin} - full single VIN decode

Documents why ZIP Enrichment, Holidays, and Air Quality were chosen:
- ZIP: 10-15k RapidAPI subscriber demand; USPS/Census free dataset
- Holidays: 50k subs on top competitor (AbstractAPI); Nager.Date gap
- AQI: 8k subs on top competitor; OpenAQ open dataset fills -49/mo gap
RapidAPI competitor subscriber counts documented for all 3 categories.
Identifies 3 new API candidates with data sources and demand evidence:
1. Business Hours API — OSM opening_hours — high revenue potential
2. Vehicle VIN Decoder — NHTSA vPIC (gov data) — high revenue potential
3. Time Zone by Coordinates — timezone-boundary-builder — medium-high
Decision: build VIN Decoder next (strongest paid demand evidence,
government data source, simple API surface).
