California municipal bond issuance — every state and local government bond, note, certificate of participation and Mello-Roos special-tax deal reported to the California Debt and Investment Advisory Commission (CDIAC) since 1984, at issue level: principal, sale date, debt type, purpose, ratings, interest cost, issuance fees and the underwriter, municipal advisor and bond counsel on the deal.

This is primary-market issuance, not the secondary trade tape. It carries no MSRB/EMMA content and no CUSIP dependency — CDIAC publishes it as California public data.

Tools

• ca_debt_search_issues(...) — search 76,000+ California issues by issuer, county, debt type, purpose, tax status, ESG label, sale date and principal amount. The workhorse.
• ca_debt_issue(cdiac_number) — full detail for one issue, including issuance costs broken out by participant (underwriter takedown, advisor fee, bond and disclosure counsel fees, trustee fee, rating agency fee) and any Annual Debt Transparency Report rows filed against it in later years.
• ca_debt_issuer_profile(issuer) — one issuer’s borrowing history: total principal, issue count, date range, breakdown by debt type and purpose, largest and most recent issues.
• ca_debt_statewide_totals() — the state treasurer’s headline totals (debt issued YTD, local debt issued YTD, proposed but unsold, recent long-term volume).
• ca_debt_filter_options(field?) — the exact wording CDIAC uses for each enumerated filter.
• ca_debt_resolve_issuer(name) — partial name → the exact issuer names CDIAC uses.

Data sources

• https://debtwatch.treasurer.ca.gov/env.json — the API base the SPA itself reads. Resolved once per isolate rather than hardcoded, with a fallback to the current value.
• PUT /api/dataset/issues/search — issuance search. PUT, not GET or POST.
• GET /api/dataset/issues — column metadata, including the accepted values for every enumerated filter.
• GET /api/dataset/issues/element/Issuer/search?q=&pageNumber=N — issuer typeahead (7,600+ issuers). Paginates at ten and ignores every page-size parameter (pageSize, take, limit all no-op) while reporting the true count in totalValues; only pageNumber works. Reading page one alone makes “san diego” look like 10 issuers when it is 47, and makes an exact name that sorts onto a later page (San Diego Unified Port District) come back as ambiguous with candidates that do not contain it. This pack pages, bounded, and reports when it stopped early.
• GET /api/report/issuance-detail-with-history/{cdiacNumber} — single-issue detail plus later ADTR filings.
• GET /api/fast-stat — headline statewide totals.

Things worth knowing before you touch this

• A malformed filter is an empty HTTP 500, not a 400. No body, no validation message. Filters are keyed by column id with a type discriminator, decoded from the SPA bundle: StringOneOf / StringContainsOneOf (options: []), DateBetween / DateOnOrAfter / DateOnOrBefore / DateEqualTo (minimum / maximum / exactly), NumberBetween / NumberGreaterThanOrEqualTo / NumberLessThanOrEqualTo, BooleanEqualTo (exactly). Anything else is a 500.
• IssuerCounty is the multi-value column and needs StringContainsOneOf; sending StringOneOf against it matches nothing without erroring.
• Text filters are exact-match on CDIAC’s spelling, and a near-miss returns a clean zero-row 200 rather than an error — Los Angeles is a different issuer from Los Angeles Unified School District. Every enum argument in this pack is resolved against the upstream’s own option list first, and every issuer argument through the typeahead endpoint, so a caller naming things the way a person would still gets rows. An argument that cannot be resolved is answered with candidates rather than dropped.
• There is no values endpoint per filter. The option lists live inline in GET /api/dataset/issues, under columns[].filter.values.all, for columns whose strategy is AllAtOnce. High-cardinality columns are ByAsyncSearchOnly and only reachable through the element/{col}/search typeahead.
• SaleDate carries future dates for proposed issues, so a descending sort surfaces deals that have not happened yet. sold_status separates them.
• Scope is California only. There is no national equivalent on a free path — MSRB/EMMA’s terms bar building a redistributable database from it.
