Is there a cheap alternative to Bloomberg Terminal — municipal bond sleeve?

Partially. Some of the product is free public data (MSRB EMMA (trades, official statements, disclosures)), but part of its value is genuinely proprietary. One terminal seat = $32k/yr. Per-CUSIP lookups at $0.25 serve advisors and agents who touch munis occasionally.

Is it legal to rebuild Bloomberg Terminal — municipal bond sleeve from public data?

Facts and public-domain government data are not copyrightable, but there are real traps here: HARD STOP: FINRA TRACE corporate-bond data is NOT free for commercial use — the muni arbitrage does NOT extend to corporates The rest of the terminal (equities L2, chat, analytics) is licensed/proprietary — this decomposition covers ONLY the muni sleeve This is research, not legal advice.

Bloomberg Terminal — municipal bond sleeve: what you're actually paying for

Partially — some of it is free public data, some is genuinely proprietary

Bloomberg Terminal — municipal bond sleeve typically costs $32,000/yr per terminal seat. Part of what it sells is free public data (MSRB EMMA (trades, official statements, disclosures)); part is genuinely proprietary. For munis specifically: convenience. MSRB's EMMA publishes real-time trade prices and continuing disclosures for free — the terminal's muni edge is workflow, not exclusive data.

The free public data underneath

Source	License	Access
MSRB EMMA (trades, official statements, disclosures)	free public access	emma.msrb.org — no official bulk API; programmatic access requires care

Rebuild recipe

Pull recent trades + disclosure events per CUSIP/issuer from EMMA's public interfaces
Surface continuing-disclosure red flags (draw notices, rating changes, defaults)
Scope honestly if programmatic access proves fragile — a disclosure-event feed alone still beats a $32k seat for the occasional muni question

DIY difficulty: moderate-to-high — EMMA has no official API; respect its terms

The price math

One terminal seat = $32k/yr. Per-CUSIP lookups at $0.25 serve advisors and agents who touch munis occasionally.

Licensing and legal traps

HARD STOP: FINRA TRACE corporate-bond data is NOT free for commercial use — the muni arbitrage does NOT extend to corporates
