At present, there’s no easy way to make a single API call to get that, but you could synthesise that information by comparing two reasonably small bodies of data. There are two bulk data downloads that you can use for this: <a href="http://ftp.ripe.net/ripe/atlas/measurements/">measurement metadata</a> (already mentioned, updated weekly) and the <a href="http://ftp.ripe.net/ripe/atlas/probes/archive/2015/10/">probe data</a> (daily). Basically, you need to do three things: <ul style="margin: 1.2em 0px;padding-left: 2em;"> <li style="margin: 0.5em 0px;">Compile a list of probe ids that represent probes within the AS you want. You can do this by looping over the probes in the daily dump and capturing the id for any probe that has <code style="font-family: Consolas,Inconsolata,Courier,monospace;margin: 0px 0.15em; padding: 0px 0.3em; white-space: pre-wrap; border: 1px solid rgb(234, 234, 234); background-color: rgb(248, 248, 248); border-radius: 3px; display: inline;">asn_v4</code> or <code style="font-family: Consolas,Inconsolata,Courier,monospace;margin: 0px 0.15em; padding: 0px 0.3em; white-space: pre-wrap; border: 1px solid rgb(234, 234, 234); background-color: rgb(248, 248, 248); border-radius: 3px; display: inline;">asn_v6</code> equal to the AS in question.</li> <li style="margin: 0.5em 0px;">Compile a list of measurements using these probes. You can do this by looping over the list of measurements, capturing the ids of measurements that have the aforementioned probe ids in the <code style="font-family: Consolas,Inconsolata,Courier,monospace;margin: 0px 0.15em; padding: 0px 0.3em; white-space: pre-wrap; border: 1px solid rgb(234, 234, 234); background-color: rgb(248, 248, 248); border-radius: 3px; display: inline;">probes</code> list.</li> <li style="margin: 0.5em 0px;"> Fetch the probe-specific data from the API using both ids: <pre style="font-family: Consolas,Inconsolata,Courier,monospace;font-size: 1em; line-height: 1.2em;margin: 1.2em 0px;"><code style="font-family: Consolas,Inconsolata,Courier,monospace;margin: 0px 0.15em; padding: 0px 0.3em; white-space: pre-wrap; border: 1px solid rgb(234, 234, 234); background-color: rgb(248, 248, 248); border-radius: 3px; display: inline;white-space: pre; overflow: auto; border-radius: 3px; border: 1px solid rgb(204, 204, 204); padding: 0.5em 0.7em; display: block ! important;"> <a class="moz-txt-link-freetext" href="https://atlas.ripe.net/api/v1/measurement/**measurement_id**/result/?prb_id=**probe_id**,**probe_id**&format=txt">https://atlas.ripe.net/api/v1/measurement/**measurement_id**/result/?prb_id=**probe_id**,**probe_id**&format=txt</a> </code></pre> </li> </ul> The above call will return all of the results for measurement <code style="font-family: Consolas,Inconsolata,Courier,monospace;margin: 0px 0.15em; padding: 0px 0.3em; white-space: pre-wrap; border: 1px solid rgb(234, 234, 234); background-color: rgb(248, 248, 248); border-radius: 3px; display: inline;">#${measurement_id}</code>, but only for probes with one of those two ids. That last bit, <code style="font-family: Consolas,Inconsolata,Courier,monospace;margin: 0px 0.15em; padding: 0px 0.3em; white-space: pre-wrap; border: 1px solid rgb(234, 234, 234); background-color: rgb(248, 248, 248); border-radius: 3px; display: inline;">format=txt</code> will ensure that the returning data is in bite-sized chunks so you don’t gobble up 30gb of memory just to parse what comes out. Write that in a loop with a reasonable wait time between each request or we’ll get mad at you and you’ve got a decent body of data to work with. Note that there’s no reason to fetch the entire history of a measurement either. You can always pass <code style="font-family: Consolas,Inconsolata,Courier,monospace;margin: 0px 0.15em; padding: 0px 0.3em; white-space: pre-wrap; border: 1px solid rgb(234, 234, 234); background-color: rgb(248, 248, 248); border-radius: 3px; display: inline;">start=<timestamp></code> to the above URL and it’ll only give you results returned since that date. <div title="MDH:SWYgSSdtIHVuZGVyc3RhbmRpbmcgeW91ciBzaXR1YXRpb24gY29ycmVjdGx5LCB5b3Ugd2FudCB0byBzZWUgYSBsaXN0IG9mIG1lYXN1cmVtZW50cyB0aGF0IGluY2x1ZGUgcHJvYmVzIGZyb20gYSBw YXJ0aWN1bGFyIEFTIGFzIHRoZWlyIHNvdXJjZS7CoCBBdCBwcmVzZW50LCB0aGVyZSdzIG5vIGVh c3kgd2F5IHRvIG1ha2UgYSBzaW5nbGUgQVBJIGNhbGwgdG8gZ2V0IHRoYXQsIGJ1dCB5b3UgY291 bGQgc3ludGhlc2lzZSB0aGF0IGluZm9ybWF0aW9uIGJ5IGNvbXBhcmluZyB0d28gcmVhc29uYWJs eSBzbWFsbCBib2RpZXMgb2YgZGF0YS48YnI+PGJyPlRoZXJlIGFyZSB0d28gYnVsayBkYXRhIGRv d25sb2FkcyB0aGF0IHlvdSBjYW4gdXNlIGZvciB0aGlzOiBbbWVhc3VyZW1lbnQgbWV0YWRhdGFd KGh0dHA6Ly9mdHAucmlwZS5uZXQvcmlwZS9hdGxhcy9tZWFzdXJlbWVudHMvKSAoYWxyZWFkeSBt ZW50aW9uZWQsIHVwZGF0ZWQgd2Vla2x5KSBhbmQgdGhlIFtwcm9iZSBkYXRhXShodHRwOi8vZnRw LnJpcGUubmV0L3JpcGUvYXRsYXMvcHJvYmVzL2FyY2hpdmUvMjAxNS8xMC8pIChkYWlseSkuPGJy Pjxicj5CYXNpY2FsbHksIHlvdSBuZWVkIHRvIGRvIHRocmVlIHRoaW5nczo8YnI+PGJyPiogKipD b21waWxlIGEgbGlzdCBvZiBwcm9iZSBpZHMgdGhhdCByZXByZXNlbnQgcHJvYmVzIHdpdGhpbiB0 aGUgQVMgeW91IHdhbnQqKi7CoCBZb3UgY2FuIGRvIHRoaXMgYnkgbG9vcGluZyBvdmVyIHRoZSBw cm9iZXMgaW4gdGhlIGRhaWx5IGR1bXAgYW5kIGNhcHR1cmluZyB0aGUgaWQgZm9yIGFueSBwcm9i ZSB0aGF0IGhhcyBgYXNuX3Y0YCBvciBgYXNuX3Y2YCBlcXVhbCB0byB0aGUgQVMgaW4gcXVlc3Rp b24uPGJyPiogKipDb21waWxlIGEgbGlzdCBvZiBtZWFzdXJlbWVudHMgdXNpbmcgdGhlc2UgcHJv YmVzKiouwqAgWW91IGNhbiBkbyB0aGlzIGJ5IGxvb3Bpbmcgb3ZlciB0aGUgbGlzdCBvZiBtZWFz dXJlbWVudHMsIGNhcHR1cmluZyB0aGUgaWRzIG9mIG1lYXN1cmVtZW50cyB0aGF0IGhhdmUgdGhl IGFmb3JlbWVudGlvbmVkIHByb2JlIGlkcyBpbiB0aGUgYHByb2Jlc2AgbGlzdC48YnI+KiBGZXRj aCB0aGUgcHJvYmUtc3BlY2lmaWMgZGF0YSBmcm9tIHRoZSBBUEkgdXNpbmcgYm90aCBpZHM6PGJy Pjxicj7CoCDCoMKgIMKgwqAgaHR0cHM6Ly9hdGxhcy5yaXBlLm5ldC9hcGkvdjEvbWVhc3VyZW1l bnQvKiptZWFzdXJlbWVudF9pZCoqL3Jlc3VsdC8/cHJiX2lkPSoqcHJvYmVfaWQqKiwqKnByb2Jl X2lkKiomYW1wO2Zvcm1hdD10eHQ8YnI+PGJyPlRoZSBhYm92ZSBjYWxsIHdpbGwgcmV0dXJuIGFs bCBvZiB0aGUgcmVzdWx0cyBmb3IgbWVhc3VyZW1lbnQgYCMke21lYXN1cmVtZW50X2lkfWAsIGJ1 dCBvbmx5IGZvciBwcm9iZXMgd2l0aCBvbmUgb2YgdGhvc2UgdHdvIGlkcy7CoCBUaGF0IGxhc3Qg Yml0LCBgZm9ybWF0PXR4dGAgd2lsbCBlbnN1cmUgdGhhdCB0aGUgcmV0dXJuaW5nIGRhdGEgaXMg aW4gYml0ZS1zaXplZCBjaHVua3Mgc28geW91IGRvbid0IGdvYmJsZSB1cCAzMGdiIG9mIG1lbW9y eSBqdXN0IHRvIHBhcnNlIHdoYXQgY29tZXMgb3V0Ljxicj48YnI+V3JpdGUgdGhhdCBpbiBhIGxv b3AgKndpdGggYSByZWFzb25hYmxlIHdhaXQgdGltZSBiZXR3ZWVuIGVhY2ggcmVxdWVzdCBvciB3 ZSdsbCBnZXQgbWFkIGF0IHlvdSogYW5kIHlvdSd2ZSBnb3QgYSBkZWNlbnQgYm9keSBvZiBkYXRh IHRvIHdvcmsgd2l0aC48YnI+PGJyPk5vdGUgdGhhdCB0aGVyZSdzIG5vIHJlYXNvbiB0byBmZXRj aCB0aGUgZW50aXJlIGhpc3Rvcnkgb2YgYSBtZWFzdXJlbWVudCBlaXRoZXIuwqAgWW91IGNhbiBh bHdheXMgcGFzcyBgc3RhcnQ9Jmx0O3RpbWVzdGFtcCZndDtgIHRvIHRoZSBhYm92ZSBVUkwgYW5k IGl0J2xsIG9ubHkgZ2l2ZSB5b3UgcmVzdWx0cyByZXR1cm5lZCBzaW5jZSB0aGF0IGRhdGUuPGJy Pg==" style="height:0;width:0;max-height:0;max-width:0;overflow:hidden;font-size:0em;padding:0;margin:0;"></div> </div> </body> </html>
