FAQ
Is there a token?
Section titled “Is there a token?”No. There is no Superspice token, and the x402 protocol itself has no token. Payments are plain USDC — a stablecoin backed 1:1 by dollars. Nothing here is speculative: agents pay dollars, sellers receive dollars.
Do I need crypto experience to sell?
Section titled “Do I need crypto experience to sell?”You need a wallet address on Base to receive your money — that’s it. No gas, no contract deployment, no token management: Superspice deploys and operates the on-chain plumbing, and your earnings arrive as USDC at the address you set. If you can paste an address into a form, you’re qualified.
What happens when a call fails?
Section titled “What happens when a call fails?”An agent never pays for a failed call — and you never serve an unpaid one. This is the Superspice Guarantee, and it’s guaranteed by architecture rather than promise:
- Payment is verified before your origin answers, so there’s no freeloading.
- The money settles only after the response is delivered. If your origin fails, the payment doesn’t settle; failed prepaid draws are re-credited automatically. A reconciliation process recovers every edge case, so a payment is never silently lost.
Can a buyer charge back a payment?
Section titled “Can a buyer charge back a payment?”No. USDC payments are cryptographic and final — there is no card network behind them and structurally nothing to dispute. The buyer’s protection is delivery-gated settlement (above), which does the job a chargeback exists to do, without the fraud surface.
Will this hurt my SEO or my human visitors?
Section titled “Will this hurt my SEO or my human visitors?”No. Human visitors always see your own domain and your normal pages — no interstitials, no checkout walls. Google and Bing search crawlers are never tolled, so indexing and ranking are untouched. Only AI agents meet the paid wall, and how they meet it is your choice of shield mode.
What if Superspice disappears?
Section titled “What if Superspice disappears?”Your money doesn’t. Payouts flow through your own on-chain splitter contract, and sweeping it to your wallet is permissionless — it works whether or not Superspice exists. Funds at your splitter are recoverable by you alone, forever. Leaving is just as undramatic: delete two DNS records and your domain is exactly as it was.
Does my origin URL become public?
Section titled “Does my origin URL become public?”No. Agents only ever see your gw.superspice.xyz gateway URL; your origin stays private
behind it. You can also have your origin reject any request that didn’t come through
Superspice — see Securing your origin.
What can I sell?
Section titled “What can I sell?”Any HTTP API (market data, search, geo, ML inference, scraping…), data feeds and datasets, tools and actions agents invoke, and website content via per-page tolls or passes. If it speaks HTTP, it can be priced.
Can my rate ever change?
Section titled “Can my rate ever change?”Only downward. Your fee rate is enforced by your on-chain splitter, and an existing seller’s rate can never be raised — the contract, not a pricing page, is what locks it.
What are USDC and Base?
Section titled “What are USDC and Base?”USDC is a regulated stablecoin redeemable 1:1 for US dollars, issued by Circle. Base is a low-cost Ethereum layer-2 network built by Coinbase, where a payment settles in about a second for a fraction of a cent. Together they make sub-cent, machine-speed payments practical — which is the whole point.
How is this different from a regular API marketplace?
Section titled “How is this different from a regular API marketplace?”Marketplaces sit between you and the money: they bill the buyer, hold the funds, take their cut, and pay you on their schedule. Superspice is non-custodial — payment settles on-chain straight to your wallet, we never hold a balance for you, and the fee is paid by the buyer on top of your price. You keep 100% of your list price and can leave any time.
