Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Microsoft Azure API Management

  • Prices are not shown on the pricing page itself; every tier renders as a placeholder and routes to the calculator or sales
  • Two parallel generations of tiers, classic and v2, so the choice is which lineage before which size
  • The Developer tier is explicitly not for production
  • Self-hosted gateways and workspace gateways are charged separately from the service

Bud Financial

  • It is an enrichment and intelligence layer, not connectivity, so most buyers also pay an aggregator and the total cost of the open banking stack is higher than the Bud contract suggests.
  • Categorisation accuracy is market specific, and merchant coverage tuned for the UK does not transfer cleanly to other countries, so non-UK buyers should insist on accuracy testing against their own data.
  • Sending complete customer transaction histories to a third party triggers a data protection and vendor risk review at any bank, and that process routinely takes longer than the technical integration itself.
  • Pricing is unpublished and blends a committed fee with usage, so an institution whose enriched volume grows faster than the value it extracts can find the contract repricing against it at renewal.
  • The product set spans enrichment, decisioning, staff analytics and consumer features, which means a buyer wanting only enrichment may be steered towards a broader platform commitment than the problem requires.

Answered from the vendors’ own pages

Source
Bud Financial: Does Bud provide open banking connections?

It can, but its differentiator is enrichment of transaction data. Many customers already have the data and buy Bud to make it usable.

Microsoft Azure API Management: What are the API request limits for Azure API Management's v2 tiers?

Basic v2 includes 10 million API requests monthly, Standard v2 includes 50 million monthly, and Premium v2 includes unlimited API requests. Additional requests beyond included amounts incur standard rates.

Source
Bud Financial: Is it UK only?

It is UK founded and its merchant coverage is strongest there, with expansion into the US. Accuracy outside the UK should be tested on your own data.

Microsoft Azure API Management: What cache capacity does each Azure API Management tier provide?

Basic v2 provides 250 MB built-in cache, Standard v2 provides 1 GB cache, and Premium v2 provides 5 GB cache capacity for response caching.

Source
Bud Financial: What does it cost?

Not published. Typically a recurring committed fee plus usage-based charges, priced by product mix and enriched transaction volume.

Bud Financial: Why not build categorisation in house?

Because it is not a one-off build. Merchant naming changes continuously and an in-house model degrades unless someone maintains it permanently, which is the cost most institutions underestimate.
