The short version

  • Each has a real cost: Astra push-to-card costs materially more per transaction than ACH, so a platform that switches all payouts to instant sees payment costs rise sharply, and the usual answer of charging the recipient for speed only works where recipients will pay.; Ozone API it provides the API layer, not the core connectivity, so the bulk of the project is still integrating your own core banking systems and that cost is not in the licence.
  • They diverge on capability: Astra covers Instant disbursements, Ozone API covers Multi-standard support.
  • Prices and features above were last checked on 1 September 2026.

Where each one falls short

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

Astra

  • Push-to-card costs materially more per transaction than ACH, so a platform that switches all payouts to instant sees payment costs rise sharply, and the usual answer of charging the recipient for speed only works where recipients will pay.
  • Original Credit Transaction support is not universal across card issuers, so a proportion of payouts fall back to slower rails and you must build and explain a two speed experience rather than promising instant to everyone.
  • The programme depends on Cross River Bank as sponsor, a bank with concentrated fintech exposure and a documented regulatory history, so a single supervisory action on that institution is a direct operational risk to your payouts.
  • Nothing is published on pricing, and per transaction economics vary by rail and volume, so small platforms cannot estimate cost before a sales conversation and have limited leverage in it.
  • FedNow reach still depends on the recipient bank participating, so instant account-to-account is not available to every recipient and the routing logic has to degrade gracefully, which is more integration work than the single API framing suggests.

Ozone API

  • It provides the API layer, not the core connectivity, so the bulk of the project is still integrating your own core banking systems and that cost is not in the licence.
  • Value is driven by regulatory obligation, so an institution not under a mandate struggles to build a business case for the spend.
  • It is a small UK vendor selling to large regulated institutions, which raises procurement and vendor viability questions during bank due diligence.
  • Premium API monetisation is a genuine capability but few banks have found real demand, so revenue projections used to justify the purchase often do not materialise.
  • Standards evolve continuously and each revision means a change programme in your own systems, even where Ozone absorbs the specification work at the API edge.

Answered from the vendors’ own pages

Astra: Who is the sponsor bank?

Cross River Bank. All banking and payment services run through that relationship, so the bank should be part of your diligence rather than an implementation detail.

Ozone API: Is this a competitor to Plaid or TrueLayer?

No, the opposite side. Ozone is bought by the bank exposing data; Plaid and TrueLayer consume it on behalf of third parties.

Astra: Do I have to prefund payouts?

Not necessarily. Astra offers a net debit arrangement where disbursements settle against a reserve rather than a permanently funded float account, which is the main working capital argument for the product.

Ozone API: Does it connect to my core banking system?

It provides the standards-compliant API surface and adapters, but connecting your core is an integration project you scope separately.

Astra: Is every payout instant?

No. Push-to-card requires the recipient card issuer to support Original Credit Transactions, and FedNow requires the recipient bank to participate. The rest fall back to ACH.

Ozone API: Which standards does it support?

UK Open Banking, Berlin Group, FDX, Consumer Data Right and Gulf regional standards, among others, from one platform.

Astra: What does it cost?

Nothing is published. Pricing is per transaction and varies by rail and volume, and card rails cost considerably more than ACH.
