Payment #12Correct to the last decimal, but it will not say when it looked

The other half of the head to head. It answered correctly, cheaply and instantly, and it is the only thing keeping it from an A that it will not tell you which block it read.

• The number was right to six decimals. 1.999671 USDC, matching the chain at the moment it was asked, with the symbol, the decimals and the raw atomic value all correct. It quoted a tenth of a cent and charged a tenth of a cent. It also publishes its rate limit in headers, 100 per window with the remaining count and reset time, which is a courtesy most sellers skip.
• It stamps generatedAt but never blockNumber. For a balance that is the difference between a citation and an assertion. A block number lets you reproduce the exact reading forever; a wall-clock timestamp only tells you when their server replied, which is not the same thing and cannot be checked. Its rival answered the identical question fourteen seconds earlier and gave the block.
• Worth knowing: it runs a wide, cheap catalogue on the same pattern. Nonce, gas, token, wallet, spreads, funding and a Polymarket read, most at a tenth of a cent, with a fuller wallet report at half a cent. On price and correctness there is nothing to fault here. On provenance there is one field missing.

Correct against the chain at that instant. The rival's answer fourteen seconds
earlier was 2.000671, higher by exactly the fee I paid it in between.
