Scrapling x402
How AI agents pay with x402 on this store
Scrapling Data does not require an API key or an account. A paid call returns HTTP 402 with seven x402 payment options, in this order: USDC on Base, Polygon, Arbitrum, and Solana; MetaMask erc7710 on Base; and USDC or USDT on BNB Chain. Card checkout covers a $2 day pass, a $25 month pass, and some packs. Failed calls are not charged.
The three-step flow
- Call a paid URL, for example
https://scraplingdata.xyz/v1/datasets/live_gpu_ram_prices/buyor the $0.001 test callhttps://scraplingdata.xyz/v1/ping. - The store returns HTTP 402. The JSON body and the
PAYMENT-REQUIREDheader list the amount, the receiving address, and theacceptsentries. - Pay one of those entries, then retry the same request with the payment proof in the payment header. If the data cannot be served, the payment is not settled.

Card checkout, if you do not want a crypto wallet
The same 402 body includes a cardPay hint. Day and month passes and some packs are sold at /v1/card:
- $2 day pass — 24 hours, paid lookups up to $1 per call, 60/min, 1,500 per UTC day
- $25 month pass — 30 days, same $1/call cap, 60/min, 2,500 per UTC day, one-time (not a subscription)
- Some downloadable packs, also listed on that card catalog
A pass is often cheaper than many small lookups. The comparison is at per-call vs a day or month pass.
FAQ
Do I need an API key?
No. Agents pay per call with x402. Humans who prefer a card can buy a $2 day pass or a $25 month pass, or some downloadable packs, at /v1/card.
Which chains can I pay on?
The 402 accepts list, in order, is: USDC on Base (Coinbase CDP), USDC on Polygon, USDC on Arbitrum, USDC on Solana, a MetaMask erc7710 option on Base, USDC on BNB Chain, and USDT on BNB Chain.
What is the MetaMask option?
The fifth accept is a Base USDC payment that uses assetTransferMethod=erc7710 and MetaMask's facilitator. Only MetaMask's newer upgraded (EIP-7702) wallets can pay this way. Regular undeployed MetaMask smart accounts are not accepted.
Is there an extra step on BNB Chain?
Yes. The first time a wallet pays in a given BNB Chain token (USDC or USDT), it must do a one-time on-chain approval that costs a little BNB for gas. Later purchases of that token are a signature only. Base, Polygon, Arbitrum, and Solana payments do not have that extra first-time step.
Are failed calls charged?
No. x402 payment is settled only after valid data is ready. Lookup misses return 404 and are not charged.
