AMFI — mutual fund scheme & NAV

tip

Status: LIVE — Real-time data from the upstream regulator. Updated on the regulator's publication cadence.

What it does

AMFI publishes daily NAV files, scheme details, and AMC mappings for every Indian mutual fund. Our API normalizes their daily text dumps into a queryable JSON surface with consistent scheme codes, ISIN cross-references, and historical NAV time-series.

Error codes

Code	Meaning	Recommended action
400	Malformed request (missing required param, invalid format)	Fix request shape. Response body includes error.field pinpointing the issue.
401	Missing or invalid Authorization header	Verify key prefix matches your tier and that the header is Authorization: Bearer ….
403	Key valid but not entitled to this endpoint	Sandbox keys cannot call live-tier endpoints. Upgrade or request entitlement.
404	Resource not found	Check identifier format. Some endpoints return 200 with empty results[] instead of 404 — verify the endpoint convention.
429	Rate limit exceeded	Honor Retry-After header. Sandbox 30 r/m, Starter 300 r/m, Growth 1500 r/m.
503	Upstream regulator unreachable after retries	Live-tier only. Sahayak retries 3× with backoff before surfacing. Implement circuit-breaker on caller side.
