Yes. No key and no signup. A signup wall on public data defeats the point of publishing it.

Can I use this commercially?

Yes, with attribution and a link back. The one thing we ask beyond that is that you carry the disclaimer: GMP is unofficial, and an API makes it easy to consume a number at a scale that quietly launders its uncertainty away.

What are the rate limits?

There is no hard limit, and responses are cached for around a minute. Please poll no more than once a minute — the data does not change faster than that, and there is one small server behind it.

Market Data API

Free · no key · no signup · updated 19 Sept 2026, 1:29 am IST

The same data the pages on this site are built from, as JSON. No Indian IPO site publishes structured data, so anyone wanting a feed currently has to scrape a table. These endpoints exist so they do not have to.

Terms, in three lines

1. Attribute Xflot with a link back.

2. Poll no more than once a minute. Responses are cached anyway, and there is one small server behind this.

3. Carry the disclaimer. Every response includes one — please keep it with the data.

Know what the GMP field is. It is unofficial, unverifiable, and where our sources disagree by more than half the premium we flag it with gmpDisputed. An API makes it easy to consume a number at a scale that quietly launders that uncertainty away. The flag is there to be read, not ignored.

Notes

All responses are JSON with ok: true and a disclaimer field.
Dates are ISO 8601 UTC. The site displays IST; the API does not convert.
Money is in rupees. issueSizeCr and valueCr are in crore.
Subscription multiples are "times", so 81.65 means 81.65×.
gmpSources is how many independent sources reported today; gmpSpread is the range between them.
Missing data is null, never zero. A GMP of 0 means a premium of zero was reported, which is not the same as none being reported.

Example

curl -s "https://xflot.com/api/public/market/ipos?status=OPEN" | jq '.ipos[] | {name, lastGmp, lastSubX}'

Something missing?

If a field you need is on a page here but not in the API, say so — it is usually a small change and the endpoints exist to be used.
