# Bond Reference Data (Terms)

> A golden copy of bond terms by ISIN: issuer LEI, dates, coupon, amounts, seniority and call, reconciled field by field from ESMA FIRDS and the US Treasury.

InfoTrie's bond reference dataset is a golden copy of bond terms, keyed by ISIN: the issuer's LEI, issue and maturity dates, coupon type, rate and frequency, floating-rate index and spread, inflation linkage, issued and outstanding amounts, seniority and call features. Several public sources give terms for the same bond; each field is chosen from one of them under a written precedence, every answer names the source of each field, and disagreements between sources go to a review queue. Terms only: no price, yield or valuation.

Status: In rollout — available on request.

## Key facts

| | |
|---|---|
| Sources | ESMA FIRDS (debt instruments admitted to EU trading venues) and the US Treasury's Fiscal Data (Treasury auctions) |
| Key | ISIN; a CUSIP is turned into its US and Canadian ISINs; search by issuer LEI too |
| Method | Field-by-field golden copy under a written precedence, each field's source named, conflicts between sources reviewed |
| Structured products | Kept, with their CFI code, but left out of search results unless asked for |
| Holders | From an ISIN, its issuer, the issuer's direct and ultimate parents, and the US funds and 13F managers holding it |
| Update frequency | Daily |
| Delivery | REST API and MCP tools (rollout), InfoTrie console datasets; Enterprise and Bespoke plans |

## FAQ

### Does it include prices or yields?

No. This dataset carries the terms of each bond only: no price, yield, spread or valuation.

### Can I search by FIGI or by name?

Not yet. Search is by ISIN, CUSIP (turned into its US and Canadian ISINs) or the issuer's LEI. A FIGI is refused, and there is no name search.

### How do I credit the sources?

Every answer names its sources by their public labels and carries the attribution to show with the data, for example ESMA, FIRDS and the U.S. Department of the Treasury, Fiscal Data.
