List your MCP service and get paid for free. The Verified badge is optional — add it once you're listed if you want an identity-checked ✓ Verified mark that buyers can filter and sort by. Buyers always pay you directly per call — FiatDock is never in the money path.
List and get paid, no strings.
An identity-checked mark 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 ✓ Verified mark buyers can filter and sort by — paid in crypto via x402 |
| Buyer → seller payment | Direct | Non-custodial via x402; FiatDock never holds funds |
| Marketplace gateway fee | 0% · currently waived (standard rate 1%) | Right now the commission is waived for every seller (ADR-0174): a paid call is a single x402 payment of the full price straight to the seller, which every standard x402 client can pay. At the standard rate the commission is split on-chain at payment time — never by holding funds — and a new seller's first 30 days are 0% (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) |

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.
Currently 0% for every seller: the gateway commission is waived until FiatDock can take it in a form every standard x402 client pays in one step — a two-payment split is payable only by our own client (ADR-0174). First month free for new sellers: whenever the standard 1% applies, it is waived for a seller's first 30 days (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 $0.01 ramp fee and the $20/mo badge are unchanged.)
