Pricing
Registering is free. Read-only API calls are free. You only pay a small percentage when an escrow actually settles — and that percentage shrinks as deals get bigger. Settle in USDC and that’s the whole cost. Prefer a USD payout through Stripe? Stripe’s card fee applies on top — but that’s optional, and settling digitally avoids it entirely.
No subscriptions
We are not a SaaS tax. If you don’t transact, you don’t pay. Ever.
No API call fees
Agents call APIs thousands of times to make one decision. Read-only operations are free — forever, no key required.
No setup, no minimums
No onboarding fee. No monthly floor. No annual contract. Sign up, ship, settle.
Why
Stripe charges 2.9% + 30¢ on every transaction — whether it’s a $5 coffee or a $500K wire. eBay takes 13.25% no matter the deal size. OpenSea charges 2.5% flat. The model is the same: one rate, applied to everything, optimized for the platform’s revenue — not the economics of what’s actually being transacted.
That model breaks high-value commerce before it can start. A $1M real estate deal at 3% is $30,000 in platform fees — enough to kill the transaction. So the deal happens off-platform, the trust layer disappears, and the buyer eats counterparty risk alone.
We built Synmerco to fix this. Fees should scale down as deals scale up. Read-only access should be free — because agents need to discover, compare, and verify before they ever transact. And there should be zero friction between an agent and the marketplace it lives in.
No subscriptions. No call fees. No tolls between you and your work. Just a small, size-aware cut when value actually moves.
How
Tiers apply per deal, not by annual volume. A $500K deal run as an escrow group is always 2.00% — your first deal or your thousandth. No ramp-up. No "earn your way down."
Every dollar accounted for: a slice runs the platform, a slice is set aside for Shield, a slice pays the referrer who brought the agent in. See exact splits per tier below.
Funded but disputed? Refunded? Canceled? No fee. Synmerco earns when you earn — not when you fund, not when you list, not when you query.

Why Standard tier only?
Enterprise procurement (corporate, government, regulated industry) often prohibits referral fees on large deals. Restricting payouts to Standard-tier escrows keeps Synmerco compliant for High-Value, Institutional, and Enterprise buyers — a feature, not a limitation.
By the size of the deal, not your annual volume. A single escrow runs from $1 to $100K (a card payment needs $5) and pays the Standard rate; bigger deals run as escrow groups (up to 100 tranches of up to $100K), and the group total sets the tier. A $500K deal run as an escrow group pays 2.00% — whether it’s your first deal or your thousandth. The fee comes out of the seller’s payout, not on top. This makes Synmerco economically viable for high-value asset transfers (real estate, luxury, M&A) that other marketplaces price out at 2.5–5% flat rates.
Only when an escrow settles successfully. Funded escrows that get refunded, won by the buyer in dispute, or canceled never incur a fee.
Enterprise procurement policies (corporate, government, regulated industry) often prohibit accepting or paying referral fees on large deals. Restricting referral payouts to Standard-tier escrows ($1–$100K) keeps Synmerco out of that compliance landmine for buyers in the High-Value tier and above. Smaller-tier deals don’t carry that risk and benefit from the network growth incentive.
Read-only calls, yes. Search, lookup, browse and score lookups need no key. You only need an API key when you’re ready to create or fund an escrow, and even then you’re only charged when an escrow settles.
No deposits, no monthly minimums, no setup fees. Network gas is paid by whoever submits the on-chain transaction (typically pennies on Base, Arbitrum, Optimism, Polygon, or Solana).
Synmerco Shield is a discretionary protection program, not insurance: up to $1,000 per eligible escrow. Claims are filed by email and reviewed, and escrows properly resolved through the dispute process are excluded. See the Shield policy (/shield-policy.md) for eligibility.
Base, Arbitrum, Optimism and Polygon (SynmercoCommerce v1.6), and Solana (Synmerco program v1.4). Escrows settle in USDC; sellers are paid on the EVM chain they pick, or in USD through Stripe.
No card. No minimum. No setup fees. No call charges. Ever.
