List your MCP service and get paid for free. The Verified badge is optional — add it once you're listed if you want a trust mark, ranking and featured eligibility. Buyers always pay you directly per call — FiatDock is never in the money path.
List and get paid, no strings.
Stand out once you're listed.
Verified is optional — list free first and add the badge whenever standing out matters. It never changes the money flow.
| Item | Cost | Notes |
|---|---|---|
| Listing a service | Free | Unlimited listings on the Free tier — a hosted endpoint or an npm package name (stdio); paid per-call listings need a hosted HTTPS endpoint |
| Verified badge | $20 / month | Identity-checked, ranking boost, featured eligibility — paid in crypto via x402 |
| Buyer → seller payment | Direct | Non-custodial via x402; FiatDock never holds funds |
| Marketplace gateway fee | 1% · 0% first month | 🎉 Launch offer: new sellers pay 0% for their first 30 days (the buyer pays 100% directly to the seller — a single x402 payment, no platform leg). After that, the buyer pays 99% to the seller and 1% to the platform in one x402 settlement, split on-chain at payment time — never by holding funds (ADR-0006 / ADR-0022) |
| Cash out to bank | provider fee + 1% | Optional — convert USDC earnings to your bank via the cash-out ramp (licensed provider) |
| Endpoint / tool | Price | Notes |
|---|---|---|
GET /v1/quote · get_quote | Free | Real net-of-fees quote before any payment |
GET /v1/token/price · token_price | Free | Real-time token price, liquidity & volume |
POST /v1/stablecoin/intel · stablecoin_intel | $0.002 | Stablecoin supply, peg deviation, per-chain breakdown — never charged if data is unavailable |
POST /v1/token/safety · token_safety | $0.01 | Honeypot / rug-risk verdict — never charged if data is unavailable |
POST /v1/offramp/session · POST /v1/onramp/session | $1.00 | Ramp session fee; malformed requests are rejected free before the paywall, and a provider outage is never charged |
All per-call fees settle in USDC on Base via x402 — no account, no API key, no subscription. The exact terms always come from the endpoint's own 402 response.
First month free for new sellers: the 1% marketplace gateway fee is waived for a seller's first 30 days — during the window a paid call is a single x402 payment of the full price straight to the seller (FiatDock takes 0%), then it reverts automatically to the 99% / 1% split (ADR-0022). Either way payments flow directly buyer-wallet → seller-wallet; FiatDock is non-custodial end to end and never holds your funds. (This is the marketplace gateway fee only — the $1.00 ramp fee and the $20/mo badge are unchanged.)
