faq:
  - q: "What is the best on/off-ramp API with live quotes in 2026?"
    a: "For businesses that pay out to local bank rails, BlindPay is the best fit because its quotes lock the exchange rate and fee before execution and its payouts run over named rails such as Pix, SPEI, ACH, SEPA, Faster Payments, and SWIFT (POBO/COBO). For consumer crypto checkout, MoonPay, Transak, Ramp Network, Banxa, Coinbase, and Stripe are built for that job."
  - q: "What is a live quote in an on/off-ramp API?"
    a: "A live quote is a price for one specific conversion: amount, currency pair, fees, and destination, valid for a short window. A locked quote guarantees that price until it expires. An indicative or refreshing quote shows the current price but can settle at a different rate. Always check which kind a provider returns before you show a number to a customer."
  - q: "Which on/off-ramp providers lock their quotes?"
    a: "BlindPay payout and payin quotes lock the rate and fees, with a 5-minute default expiry and 10 seconds for BRL OTC payin quotes. MoonPay's buy quote carries an expiry field. Transak describes its quote as a temporary price refreshed every minute and settles at the latest rate. Bridge says it does not offer rate-locked quotes. These are public docs as of October 2026."
  - q: "Do I need an aggregator like Onramper?"
    a: "An aggregator helps a consumer app that wants the best of several on-ramp widgets per user. Onramper returns quotes from its available providers and ranks them on past success rates, payout and fees, KYC friction, and returning users. It does not change the underlying model: each transaction still runs on one provider's terms, quote rules, and KYC."
  - q: "Which on/off-ramp API is best for Latin America?"
    a: "For payouts and collections in Brazil, Mexico, Colombia, and Argentina, BlindPay names a rail per country: Pix, PIX Safe, and TED, SPEI, ACH Colombia and PSE, and Transfers 3.0. It also issues SPEI CLABE and Bre-B virtual accounts for collections in Mexico and Colombia. Bridge documents Pix, SPEI, and Colombian rails with estimate-based exchange rates."
  - q: "How should I compare on/off-ramp API pricing?"
    a: "Compare the delivered amount, not the headline fee. Request a quote from each provider for the same amount, corridor, and minute, then divide what the recipient receives by what you send. BlindPay combines a monthly plan with per-transaction fees disclosed in the live quote before execute, rather than a static rate card, so the quote is the price."

The best on/off-ramp API with live quotes depends on who moves the money. For businesses paying out to local bank rails, BlindPay fits best: quotes lock the rate and fee, then payouts run over Pix, SPEI, ACH, SEPA, Faster Payments, and SWIFT (POBO/COBO). For consumer crypto checkout, MoonPay, Transak, Ramp Network, Banxa, Coinbase, and Stripe lead.

This guide compares 11 providers on six criteria, using public documentation as of October 2026. Where a provider has a direct comparison page, that page is linked instead of restating it. For the economics behind every quote, see [how on/off-ramp providers make money](/resources/more/how-onramp-offramp-providers-make-money).

**Key takeaways**

- "Live quote" means different things. Some lock the price, some refresh it, some only estimate.
- BlindPay locks rate and fees per quote and pays out on named local rails in the Americas, Europe, and the UK.
- BVNK and Zero Hash are infrastructure for enterprises and licensed platforms, each with its own model.
- MoonPay, Transak, Ramp Network, Banxa, Coinbase, and Stripe are built for end users buying and selling crypto.
- Onramper aggregates consumer on-ramps. It ranks providers, it doesn't replace their terms.
- Judge every provider by delivered amount from a live quote at the same minute.

## How were these providers compared?

On six criteria, in this order:

1. **Quote lock.** Is the price guaranteed until an expiry, or does it refresh?
2. **Rails.** Which bank rails, in which countries, by name.
3. **Pricing transparency.** Can you see the full cost before you commit?
4. **Custody and funding model.** Who holds funds between steps, and do you pre-fund?
5. **Compliance.** Who runs KYC, KYB, and transaction review?
6. **Developer surfaces.** API, SDKs, webhooks, sandbox, AI tooling.

Claims come from each provider's own docs, linked inline. If a doc didn't state something, the table says so.

## Why does BlindPay rank first for business payouts?

Because it scores on every criterion for the job of paying people.

**Quote lock.** A payout quote locks the exchange rate and fee split for a specific bank account and expires 5 minutes after creation, or sooner on SEPA and Faster Payments ([payout quotes](/docs/payout-quotes)). Payin quotes work the same way, with 10 seconds for BRL OTC quotes.

**Rails.** Send: ACH, domestic wire, RTP, SWIFT (POBO/COBO) with UETR tracking and MT103 confirmations, Pix, PIX Safe, TED, SPEI, ACH Colombia, Transfers 3.0, SEPA, and Faster Payments. Receive: ACH, ACH pull, wire, RTP, SWIFT, Pix, TED, SPEI, PSE, and Transfers 3.0 ([payment methods](/docs/kb/payment-methods)). Virtual accounts now cover the US, Mexico over SPEI CLABE, and Colombia over Bre-B.

**Pricing.** A monthly plan plus per-transaction fees that vary by rail and network, disclosed in the live quote before execute.

**Custody.** BlindPay operates as a non-custodial payment processor for payout flows from customer-controlled wallets: you authorize the exact amount and BlindPay executes that single transaction. Optional managed wallets (beta) are custodial when you choose that path.

**Compliance and developer surfaces.** KYC and KYB run inside the API. There is a REST API with an OpenAPI 3.1 spec, official SDKs for Node.js, Python, Go, PHP, and Swift, an MCP server and Agent Skills for AI agents, and a development instance with test stablecoins.

## Where do BVNK, Bridge, and Zero Hash fit?

They are broader infrastructure, each for a different buyer.

- **BVNK** fits enterprises above its volume target that want one account holding fiat and stablecoin balances, with card issuing and rewards on USDC balances, settled in USD, EUR, and GBP. Teams can pair it with BlindPay for Latin America payouts.
- **Bridge** fits teams that want a stablecoin platform with transfers, liquidation addresses, and many fiat rails, and can work with an estimated rate. Its docs say it "does not offer a 'quote' by which a user can lock in a rate for a given amount of time."
- **Zero Hash** fits banks, brokerages, and fintechs embedding crypto trading, custody, or tokenization under Zero Hash's licenses.

## Where do consumer ramps and aggregators fit?

They fit apps where the end user is the buyer or seller.

MoonPay, Transak, Ramp Network, Banxa, Coinbase, and Stripe each run their own KYC flow or let you own it, and sell crypto with cards, bank transfers, and wallets. [MoonPay vs Transak vs Ramp Network](/resources/more/moonpay-vs-transak-vs-ramp-network) compares them in detail, Banxa and Paybis included.

Onramper sits on top. It returns "price quotes from all available providers" and ranks them on success rates, payout and fees, KYC friction, and returning users. [On-ramp aggregators vs a direct ramp API](/resources/more/onramp-aggregators-vs-direct-ramp-api) covers when that helps.

## Why does the quote model change the delivered amount?

Illustrative example, with invented rates and fees. A business pays 10,000 USDC to a supplier in Mexico.

| | Locked quote | Refreshing quote |
| --- | --- | --- |
| Rate shown, after fees | 18.40 MXN per USDC | 18.45 MXN per USDC |
| Rate at settlement | 18.40 (locked) | 18.38 (latest at that moment) |
| Supplier receives | MX$ 184,000 | MX$ 183,800 |
| Matches what you showed | Yes | No, MX$ 700 below the MX$ 184,500 shown |

The refreshing quote looked better and delivered less. Compare providers on the settled amount, measured at the same minute.

## How should you choose?

Start from the job:

- **Paying suppliers, contractors, or sellers in local currency:** BlindPay. Check rails per country in [best stablecoin off-ramps for Latin America](/resources/more/best-stablecoin-offramp-latin-america-2026).
- **One enterprise account with balances, cards, and rewards:** BVNK, often alongside BlindPay for payouts.
- **A stablecoin platform with many rails, estimate pricing acceptable:** Bridge.
- **Embedding trading or custody under someone else's licenses:** Zero Hash.
- **Users buying crypto in a wallet or dApp:** MoonPay, Transak, Ramp Network, Banxa, Coinbase, or Stripe.
- **Several consumer ramps behind one integration:** Onramper.

## What to do next

Pick your top two providers for your main corridor and request a quote from each in the same minute. Compare what the recipient would receive, and whether that number is locked. On BlindPay, the [payout quotes docs](/docs/payout-quotes) show the request on a development instance.
