Alchemy PayScore 42Hybrid fiat-crypto ramp with genuinely deep local-rail coverage (UPI, PIX, SPEI, African mobile money) and published numeric KYC tiers, but no public fee schedule anywhere, a licence story whose numbered registers (NMLS, AUSTRAC) belong to entities that are NOT the regional buyer's counterparty, and a sampled UPI all-in near 20%.Strength: Kyc friction time to coins — 6/10Watch-out: The widget will quote you a rate whose spread is never disclosed and can be enormous on exactly the rails this segment exists for — a sampled ₹22,153 UPI purchase delivered USDT at ₹111.9 apiece against the ₹95.79 interbank rate embedded in the same API response, a 19.7% all-in the buyer only discovers by doing the maths on the delivered amount — and if Alchemy Pay rejects your order after capture, clause 6.5 lets it charge you a processing fee to refund your own money.KoyweScore 41Chilean-anchored LATAM payments and treasury API (Koywe SpA, CMF register N°196; Alerce Argentina SRL, CNV PSAV N°24) whose ONRAMP product converts local-rail fiat (PIX, SPEI, PSE, Khipu) to crypto delivered to merchant-registered external wallets — register-verified licences, but zero public end-user pricing.Strength: Licence identity — 6/10Watch-out: You cannot see a price before you onboard: Koywe is a KYB-gated B2B API, the pricing pages 404, the fee schedule lives 'informadas en la Plataforma' behind login, and the only public number is a non-binding '0.5% - 2%' typical range in the developer docs — a buyer commits to merchant onboarding before learning what the PIX-to-USDC conversion actually costs.

FactKoyweAlchemy Pay
PricingSnapshotNo end-user fee schedule is published. Koywe developer docs "Quotes and exchange rates" (https://docs.koywe.com/en/core-concepts/quotes-and-exchange-rates), fetched 29 September 2026, HTTP 200, give only an integrator-facing typical range: Processing Fee, "All transactions", "0.5% - 2%"; Network Fee "Variable (blockchain fees)"; country-specific taxes on amount and on fee. The spread is acknowledged in the docs' example ("Slightly lower than buy rate (spread)") but not quantified or benchmarked. The pricing routes www.koywe.com/en/pricing and /es/precios still return HTTP 404 (29 September 2026). The Terms ("Fecha de última actualización: 18 de mayo de 2026") put actual fees behind login or contract: "El uso de los Servicios estará sujeto al pago de las Comisiones y tipo de cambio vigentes informadas en la Plataforma o establecidas en la documentación contractual aplicable." No representative purchase can be reconstructed: the quote API needs KYB-gated credentials and there is no public widget.No fee schedule is published. The Alchemy Pay docs page "Fiat currencies, Payment Method Coverages plus Other Details" (https://alchemypay.readme.io/docs/fiat-currency-country-payment-method-coverage-plus-fees-and-limits.md, updatedAt 21 November 2025), fetched 29 September 2026, HTTP 200, links a Notion table "On-Ramp Payment Methods" whose columns (processing time, KYC countries, currencies, KYC level, pay-way code, method type, minimum, maximum and daily limits, documents) include no fee column (read through the Notion API on 29 September 2026). The Crypto Ramp Terms ("Last updated: Dec 25, 2025") say only "9.1 All fees payable under this Agreement are displayed during the purchase flow", and the marketing page says "Your users will appreciate the lowest fees in the industry." Sampled from Alchemy Pay's public quote API on 29 September 2026 (not published prices): a card quote for 200 euros carried a ramp fee of 4.19 percent and delivered about 4.3 percent less USDT than the USD rate in the same response; a Pix quote for 1,206 reais carried a 2.67 percent ramp fee and about 4.5 percent all-in; a UPI quote returned no data that day.

Score dimensions
weights sum to 86
The published score is five dimensions, each weighted for the category. "Published criteria" is the criteria block above; the other four are the engine's own terms — availability, friction, trust record, measured data. Each bar is one side's points out of that dimension's maximum; the weight beside the name is its points of the 86-point weighted total. The published criteria above can fill 24 of the block’s 30. A weight marked “constant here” belongs to a dimension every ranked product in the category holds at the same value: it still counts in the total, and it orders nothing here.
