We track 100K bond ISINs of which ca. 80K are frequently priced (i.e. at least one transaction in past 2 weeks). They cover 32 currencies, 127 issuer countries and about 6,800 corporate issuers. We have built a proprietary methodology for curves fitting: ca. 3,700 curves are fitted on a daily basis, 2,484 of them public (rest available in the STUDIO tier). React + FastAPI.
