Zopa API v0.5, A new techie toy to play with Options

[dave]

We're cooking up a Zopa API, but we thought we'd release an alpha version to see what you can do with it.

We've taken the XML data we use for the online marketplace screens and made it accessible directly via a URL.

You'll need to go to:

http://www.zopa.com/ZopaWeb/Reports/Marketplace/

and add one of the following filenames on the end (Explanation of data in brackets):

borrowers.xml (Details of Zopa borrowers)
demand.xml (Total amount requested by market in the last 7 days from our loan calculator)
lenders.xml (Details of Zopa lenders)
money.xml (Total amount offered in each market)
newmembers.xml (Details of the most recent Zopa members)
overview.xml (6 key stats from Zopa today)
rates.xml (Average rates for last 5 loans applied for by market)
zopas.xml (The high / low rates offered by lenders in a market, and the high / low of the Zopa in each market)

Any questions - just shout!

What else would you like to see included here?

Hi

Could I get up to date urls for all of the xml files available in the API. I might have a go at knocking something together too.

Thanks in advance

That doesn't help. If it is supposed to be a witty response to say go back a page I have. There is a link to the http://www.zopa.com/WebApi/flashapi.ashx which kinda works but I was asking for some more official info.

The api urls are:

http://uk.zopa.com/marketplace/borrowers.xml
http://uk.zopa.com/marketplace/demand.xml
http://uk.zopa.com/Marketplace/lenders.xml
http://uk.zopa.com/marketplace/newmembers.xml
http://uk.zopa.com/Marketplace/new-money.xml
http://uk.zopa.com/marketplace/overview.xml
http://uk.zopa.com/marketplace/rates.xml
http://uk.zopa.com/marketplace/zopas.xml

There's a few odd things in this:
new-money.xml - doesn't list the Y markets
rates.xml - The A* 60 and both Y markets have rates of 0.1%, which is obviously some mistake

There's no information on listings.
There's probably a lot more missing information that would be useful, but I haven't been through this enough yet. I would imagine that details of the loan that have gone through would be very useful

Install the Firebug console for Firefox, then enable the "Net" panel. If you go to the markets graphs pages you should see all the API calls being made by the flash movies. I haven't got them all documented, but I'm sure you'll find it rewarding to work them out yourselves

not at all, I was trying to give you a link to this thread.

Hi Ed,

Are there new versions of these feeds then? If not, should we be using calls to flashapi.ashx or is there no current official api?

Thanks

Ahh I see. Sorry and thanks

P.S the Market Information link mentioned in this thread doesn't seem to work:
http://uk.zopa.com/ZopaWeb/MI/

The MI data was removed well over a year ago!

Please shout if you're planning to turn them off - most of the data I plot comes from those feeds!

The feeds are no longer supported. We'll leave them on for now as you may be able to extract useful data, but we won't be developing them, or fixing them if they break.
In case you didn't get the new feeds, they are:

http://uk.zopa.com/api/markets/marketdemand.xml (7 day borrower demand)
http://uk.zopa.com/api/markets/marketmoney.xml (total money in each market)
http://uk.zopa.com/api/markets/marketrecentrates.xml (average rates of last 5 loans)
http://uk.zopa.com/api/markets/marketzopas.xml (the ZOPAs)
http://uk.zopa.com/api/markets/marketmoney...cumulative=true (Rate distribution, with example parameters)
http://uk.zopa.com/api/general/homepagenews.xml (the homepage news feed)

Each of these feeds can be accessed as an html table, or a JSON data feed by change the extensions to .html and .json respectively.

Hi Elljay,

Is there any way of getting a feed to show my position in the lending queue for each market? It would be great to see the number of lenders ahead in the queue and total cash on offer.

At present I have to copy/paste out of the window that appears upon clicking the market tab in the lending offers page. An automated method would be really useful.

I'm in the middle of writing an iPhone application that will be downloadable for free. For starters it will just show the 5 charts available on the lender's dashboard. I've actually compressed it into 3 charts by combining zopas/recent rates and demand/money.
Would zopa have any objections if I used any of their graphics in the app or used 'Zopa' in the title?

A reasonable request, I should think. I have referred this to Zopa fo comment.

There seems to be an issue with the json feeds. The xml and html feeds are working.

Sorry for the delay as I have just seen your post. I'll sit down with the development team and work with them on getting this running correctly.

Can you please provide an example request that no longer works - I can trace it quicker that way.

Hi Roger,
I use this url as one of my requests from the ZopaCheck app:
http://uk.zopa.com/api/markets/marketzopas.json

The XML and HTML extensions seem to work so I thought maybe the JSON was disabled?
I've been working with something else recently that polls the JSON feeds every 30 minutes. I hope this didn't cause any problems?

I've made some changes this end. Can you let me know if you see any more errors.

Polling any of the interfaces every 30 mins will not be an issue from my point of view.

Thanks for sorting it out . Will let you know if I notice anything else

Hullo
Is there an api to the default rates? It seems to me that this is a key piece of information in understanding the actual rate of returns. I can see that the data are available in the plots of default rates, but since they are so volatile, it seems reasonable to make them available through the api.
