For teams who need more, the paid data tier adds:
api.accelbrief.com.Built for VC scouts, devtool teams, and founders who pay for timing. Indicative pricing $99–500/month, by seat or API volume; checkout via merchant-of-record (Lemon Squeezy / Dodo) with a proper invoice.
The free tier is provided as-is for personal and evaluation use. Don't hammer it (it's a static file — cache it), don't resell it, and credit Accelbrief if you publish from it. Commercial or bulk use needs the paid tier.
Email care@accelbrief.com with your use case and volume and we'll set you up with a key and the right tier.
