How this service works
The Statement. REQUIRES ?wallet= on the paid request — a signed request without it is refused before the gate and no money moves. A signed JSON transfer record for one wallet on the supported EVM network or Solana selected by network (see the item input contract) — coverage (complete or window_unreadable), the exact block window (slots on Solana, and the artifact says which) and chain head at read, inflows and outflows each with count and total over the whole window plus up …
Output
A signed JSON document containing: full or partial coverage indication, the exact block window and chain head at read time, inflow and outflow counts and totals across the window, up to 200 individual transfers each with transaction hash, counterparty address, amount, and block number, a count of how many transfers are listed, an evidence hash bound into a purchase certificate's attests field, a timestamp, and a stable permanent URL where the statement can be retrieved for free indefinitely.
Example use cases
Audit agent wallet activity
“Give me a signed statement of all USDC in and out for my agent wallet 0xDead...Beef on Base over the last 3 hours — I need the evidence hash and a permanent link to the record.”
Verify counterparty payment history
“Can you pull a cryptographically attested USDC transfer record for wallet 0x1234...5678 on Polygon over the past 8 hours? I want to see their inflows and outflows before we transact.”
Document treasury flows for compliance
“Generate a signed USDC activity statement for treasury wallet 0xAaaa...Bbbb on Base for the default 6-hour window — label it 'MyDAO Treasury Agent' and give me the permanent statement URL.”

Endpoint
GEThttps://scvd.store/api/buy/the_statement?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a cryptographically signed, permanently accessible record of USDC transfers for a specific EVM wallet on Base or Polygon — particularly when auditability, attestation, or downstream verification of the statement is required. Prefer this over raw RPC queries or block explorer lookups when you need a structured, signed artifact with an evidence hash suitable for use in certificates or compliance workflows.
Side effects
- Invalid or malformed wallet address returns an error response
- Unsupported network value returns a rejection

- window_unreadable coverage returned if chain data is incomplete for the requested window
- Payment not received or x402 flow not completed results in no statement issued
