Data Pipelines on API Coding

A Tiny ETL Binary Competes With curl, jq and SQLite in a Cron Job, So Build It That Small

Mon, 05 Oct 2026 00:00:00 +0000

The real competitor is a shell script in a crontab, and it usually looks like this:

curl -s "https://api.example.com/v1/launches?limit=100" \
  | jq -r '.data[] | [.id, .name, .net] | @csv' \
  | sqlite3 -csv launches.db ".import /dev/stdin launches"

It works on the day you write it. Then the API answers 429 and curl pipes an error page into jq. Or the API has a second page, and the script never asks for it. When the job dies halfway, the rerun inserts the same rows again or trips over the primary key, depending on how the table was made. A field that starts arriving as a string goes unnoticed until a chart looks wrong. Retries, backoff, pagination, incremental state, idempotent writes and schema drift: that’s the list, and shell scripts get every item on it wrong in predictable ways. (To be fair, curl --retry covers the first two.)

Make for APIs: Rerun Only the Steps Downstream of an Endpoint That Changed

Mon, 05 Oct 2026 00:00:00 +0000

A nightly job pulls a users endpoint and an orders endpoint, normalizes both, joins them on customer ID and renders a report. On most nights the upstream data hasn’t changed since the last run. The job doesn’t know that, so it downloads and parses everything, reruns every transform and writes the same report again. If the API bills per call, or one step takes twenty minutes, you pay for the same answer every night.

The Best Small Infrastructure Tools Reduce Data Near the Source Instead of Storing More

Mon, 05 Oct 2026 00:00:00 +0000

A gigabyte of disk costs almost nothing. The same gigabyte sent to a log vendor that prices by ingestion costs real money, and pasted into a model’s context window it costs money and answer quality at the same time. Storage is cheap per byte. Everything that touches the bytes afterward is not: ingestion fees, query time, bandwidth on a thin link, a context window that holds only so much, and the attention of whoever has to read the result. Observability is the oldest place this shows up, and agents have just made it louder.

Audit an API Field's Completeness Before You Build a Feature on It

Mon, 21 Sep 2026 00:00:00 +0000

An API’s documentation lists the fields a record can have. It rarely tells you how many records actually have them. Those are different numbers, and on open data APIs the gap is often enormous.

The failure looks like this. You read the schema, spot a field that would make a great feature, build the feature, and then discover the field is populated on four percent of the data. By then the feature is written and the pitch has been made.

Why Private Domain Data Is the Real Key to AI That Actually Works

Tue, 28 Apr 2026 00:00:00 +0000

Every enterprise racing to deploy AI hits the same wall eventually: the outputs are technically impressive but commercially useless. The model knows everything about everything and nothing about your business. That gap — between general capability and contextual intelligence — is a data problem, and it’s the problem KeyAPI.ai is built to solve.

The Generic AI Problem Is a Data Problem

General large language models are trained on public datasets. That makes them broadly knowledgeable and entirely generic. Ask one to help with e-commerce user preference analysis, social media content strategy, or brand marketing targeting, and it will produce polished, plausible, competely undifferentiated output. It has no idea what your customers actually buy, what your community actually says, or what your competitors are actually doing.
