papertax

Buy the full report for one wallet and tax year ($29 up to 500 events, $59 up to 5,000, $99 above; upgrades charge the difference). method "card" charges the account owner's saved card: needs Authorization: Bearer ptx_… and the owner's opt-in; set max_price_cents to cap it. method "usdc" returns a quote: send exactly that USDC amount on HyperEVM (chain 999) to the given address, then call again with quote_id and tx_hash. (x402 clients can instead pay in USDC on Base or Solana at GET https://papertax.xyz/api/buy?address=…&year=….) Returns an unlock_token and export links. This spends money: confirm with the user first.

Read a wallet's results for one tax year from the chain and return a public, signed link (https://papertax.xyz/v/…) with a share image, for posting on X or anywhere else. Free, and nothing is stored. Dollar amounts are included only when amounts is true. With private true (the default) the wallet address is left out of the link and the page; with private false the page shows it, so check with the user first. It proves what the wallet did, not who owns it.
