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.

Quick start

```bash

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.

The authenticated endpoint

Paid keys hit a live, query-able endpoint (the free file is a static snapshot; this is fresh and filterable):

```

GET https://mfumtfkvkimxdyafncfl.supabase.co/functions/v1/data-api

Header: x-api-key: ak_live_…

Query: ?category=inference&language=Rust&min_velocity=200&limit=50

```

```bash

curl -H "x-api-key: ak_live_xxx" \

"https://mfumtfkvkimxdyafncfl.supabase.co/functions/v1/data-api?limit=20&min_velocity=100"

```

The response includes your plan, monthly_limit, and used count alongside the items.

Rate limits are per calendar month by plan. (A custom api.accelbrief.com domain can be

pointed at this endpoint later.)

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.
