Pricing
The APEX data API is paid per call over x402. No account, no API key, no subscription: you pay only for a call you make, and every payment goes to the public APEX faucet.
Prices are set in US dollars. You pay them in USDC on Arc (chain 5042), USDC on Base (chain 8453), USDC on Solana mainnet (1 USDC = $1), or in XNT on X1 at the live rate. Every 402 we return lists all of these, Arc first. The exact XNT amount for each call is in the 402 response and in /.well-known/x402. When no XNT rate is available, only USDC is offered, rather than a guessed XNT price.

How to pay
With a standard x402 client (recommended)
- Call the endpoint. It answers
HTTP 402with aPAYMENT-REQUIREDheader carrying anaccepts[]entry per rail —eip155:5042(Arc),eip155:8453(Base) andsolana:5eykt4Us...— each with the exact amount,payToand asset. The Solana entry also carries our fee payer inextra.feePayer. - Your client signs the USDC transfer and sends it in the
PAYMENT-SIGNATUREheader. You need USDC only; our fee payer covers the Solana network fee. - We check the transaction, settle it on Solana, and return the data with a
PAYMENT-RESPONSEheader naming the transaction. Nothing is served before Solana confirms the payment.
No crypto wallet? The $5 card pass
Pay $5 by card at /pass/ (tax included) and get a key worth $5 of calls at the prices below. Send it in the X-APEX-PASS header; each call takes its list price off the balance, and a call we fail to answer is not charged. The agent passports need an on-chain payment and are not sold against a pass.
Or pay yourself and replay
- Send the amount from
accepts[]to thepayToin the entry for the chain you are paying on. On Solana and X1 that isHYiepS7mNCVVKoaDmZLQ6rNtMWHTQqKheM1NLGn1x8kJ— the same address on both chains. On Arc and Base it is the EVM address in that entry; do not reuse the Solana one. - Repeat the request with the transaction signature in
X-PAYMENT-SOL(USDC) orX-PAYMENT(XNT). The server checks the payment on chain and returns the data.
Every payment unlocks one call, once. A replayed payment is refused, and a self-sent signature must be less than one hour old. Machine-readable: OpenAPI, x402 discovery. Terms: terms of use.
