Four tools on one bench.

Ticker API

Private alpha · Financial data

Financial-market data infrastructure for applications, analysis, and research.

One dependable source for Indian mutual fund and ETF data. Scheduled pipelines ingest it into our own store, so reads never depend on an upstream site being available. It is also what ArkFolio reads from.

Indian mutual funds & ETFs Owns its data

Scattered, then structured.Editorial study

Coverage · open a row for the evidence behind it

Mutual fund NAV and history Available internally

Roadmap Phase 0 verified end to end at 14,219 schemes; Phase 1 completed a ~5-year backfill of 62/62 windows into the nav hypertable.

Scheme catalogue and categories Available internally

Phase 1 complete: normalized category_group / sub_category taxonomy on the funds table, with filters and facets.

Returns and drawdown analytics Available internally

Phase 2 complete: trailing 1M-5Y/YTD/since-inception, point-to-point, rolling-window statistics, and maximum drawdown.

Data quality and freshness Available internally

Phase 1 dq_findings scan for jumps, gaps, stale and non-positive NAV; Phase 4 adds freshness gauges. Every ingestion run is recorded.

ETF market prices Partial coverage

Phase 6 is code complete for NSE v1 (prices table, ingestion, reads, DQ checks), but the roadmap still lists a stale/unmapped/divergence DQ review as outstanding.

Monthly scheme holdings In development

Phase 5 is in stabilization: seven AMC profiles are fixture-tested, HDFC is unsupported pending a verified source, Kotak is weight-only, and 38 of 56 AMCs have no code yet.

Verified 2026-08-06 by read-only inspection of the Ticker API repository. No endpoint path or credential is published here.

Built to earn its keep, one product at a time.

Four products across finance, nutrition, developer tooling, and market data look unrelated until you notice what they have in common: each one takes data that is messy, scattered, or hard to trust, and turns it into something you can act on. Ticker API feeds ArkFolio. The rest earn their place the same way.

A silent editorial film: a blue paper arch, precisely cut templates, a folded-paper food still life, ordered archival sheets, and a shared workbench. Ends with “Four tools on one bench” and the names ArkFolio, APIWatch, MacroArk and Ticker API. Created from Higgsfield-generated artwork.

Honest stages

Every product is labelled at whatever stage it is really in, not polished up to look further along. One of the four has no public access at all, and the page says so.

Evidence over claims

Explore real demo data, readable machine output, and the evidence behind each coverage state. Every recorded stage carries its verification date.

Real captures only

Product captures come from running software. Editorial studies express the ideas behind the tools; they never stand in for a product interface.

One address for everything.

Product feedback, bug reports, early-access requests, collaboration, or business enquiries — all of it goes to the same place.
