Accelbrief Data API

The same signal that powers the newsletter — what's accelerating in open-source AI, ranked by stars/day — as a structured, machine-readable feed. Operated by Nestaa.

The endpoint (live, free tier)

```

GET https://accelbrief.com/api/accelerating.json

```

No key required for the free tier. It returns every repo we've featured across all editions, deduped and labelled, refreshed each time we publish.

Top 10 by velocity, right now

curl -s https://accelbrief.com/api/accelerating.json \

| jq '.items | sort_by(-.velocity_per_day) | .[0:10]'

```

```python

import requests

data = requests.get("https://accelbrief.com/api/accelerating.json").json()

hot = sorted(data["items"], key=lambda r: r["velocity_per_day"] or 0, reverse=True)

for r in hot[:10]:

print(f"{r['velocity_per_day']:>7.0f}/day {r['repo']} ({r['category']})")

```

Field reference

• repo — owner/name on GitHub.
• url — canonical repository link, verified live at publish.
• stars — total stars at the time of the edition (a lagging number; we don't rank on it).
• velocity_per_day — stars/day, the acceleration signal we actually rank by.
• language — primary language, where detected.
• category — the edition theme (e.g. inference & serving, agents, retrieval).
• edition — the edition slug it appeared in.
• date — edition date (YYYY-MM-DD).

Free tier vs. paid

The free JSON above is the curated, published set — great for personal dashboards, eval, and one-off lookups. Attribution to accelbrief.com is appreciated.

For teams who need more, the paid data tier adds:

• Daily refresh & history — the full velocity time-series, not just the published snapshot.
• The raw firehose — accelerating repos before they make an edition, filtered to AI.
• Query & webhooks — filter by category/language/threshold; get pushed alerts when something crosses a velocity bar.
• Higher limits & an API key, served from api.accelbrief.com.
• Commercial license for redistribution inside your product.

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.

Terms

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.
