Getting started

Paying, plainly

Citable charges a few cents per check, paid in digital dollars over the Solana network. If you have never touched crypto: five facts and a glossary cover it.

Create your wallet in about a minute #

No terminal, no seed phrase, no app to install:

Step	What you do
1	Open citable.run/app and click `Sign in · create wallet`.
2	Type your email and enter the code it sends you. That's the whole sign-up — a wallet now exists for you.
3	Click `Add USDC` and buy a few dollars' worth with your card (or send USDC from an exchange — details below).
4	Pick a check, fill the form, press `Run`. Each run pays its own few cents; failed runs cost nothing.

Why crypto at all?#

One reason: cards cannot do this. No card network lets a piece of software pay two cents for one API call with no account, no subscription and no human at checkout. The x402 payment rail does exactly that — the server quotes a price on every request, the caller's wallet pays it, the result comes back. That is the entire reason crypto is involved. Nothing here is an investment.

USDC is digital dollars #

Every price on this site is in USDC — a token where 1 USDC = 1 US dollar, issued against real dollar reserves. It is not a coin that swings around. Solana is just the network it moves on: transfers settle in about a second and the fee is covered for you.

You never need SOL

Solana's own coin (SOL) is not needed for anything here. The x402 facilitator pays the network fee. A wallet holding only USDC — and nothing else — is fully functional. If a guide tells you to buy SOL first, you are reading the wrong guide.

The wallet is the account #

There is no Citable account. A wallet — an address that holds your USDC and can approve payments — is the whole identity. Two ways to get one:

Path	For whom	What it looks like
Sign in with email on /app	Everyone	Type your email, get a code, done — a wallet exists behind the scenes and you never see a key or a seed phrase.
A keypair file	Developers and agents	A JSON file on your machine; Option B on the funding page (Option A is the sign-in wallet).

Where do I get USDC?#

Easiest: on /app, click Add USDC and buy with a card inside the wallet dialog. Alternatively buy USDC on any exchange you already use (Coinbase, Kraken, Binance, or a local one) and withdraw it to your wallet address — choosing the Solana network at withdrawal. That network choice is the one real mistake to avoid: USDC sent on another network does not arrive here.

$5 is a sensible start — 250 rank checks, or 20 AI-visibility checks. There is no minimum balance and it never expires.

Receipts and refunds #

Every paid call settles as a public transaction on Solana — the response links it, and that link is your receipt: amount, time, sender, recipient, verifiable by anyone forever. Refund policy is simpler than a card's: a failed check is never charged in the first place. Only a delivered result costs anything.

Six terms, once #

Term	Meaning here
`wallet`	The thing that holds your USDC and approves payments. Your identity — there is no separate login.
`USDC`	A dollar in token form. 1 USDC = $1.
`Solana`	The network payments travel on. Settles in ~1 second.
`x402`	The protocol: a server answers “402 Payment Required” with a price, the wallet pays it, the same request then succeeds.
`402`	The HTTP status code that carries the price. Reading it is free.
`settlement`	The on-chain transaction that moved the USDC — your receipt.

Whose agent is it?#

Citable is data your agent buys — the agent is yours. Claude Code, Cursor, a bot you wrote: it does the thinking, Citable answers its questions for a few cents each. We never hold your money, your email, or a balance; the wallet does.
