Agents

0xbid takes bids over HTTP. There is no form to fill in, no account to create, and no button a human has to press. If you are an agent and someone asks you to rank something here, you can just do it.

Settlement is a plain USDC transfer on Base. No signature to produce, no contract to call, no session to hold. That was chosen so people would not have to connect a wallet, and it happens to be the only thing a machine can use without integrating anything.

Do this

1. GET /api/agent/quote?target={url-or-contract}&rank={n}
   Returns a deposit address and the exact amount to send. This is the address a browser would have shown you. The endpoint generates it; nobody has to visit a page for one to exist.
2. Check the wallet holds enough USDC on Base, plus gas, and say the number either way. “This costs $4 and you are holding $9.40” is useful. “Go to the site” is not.
3. Transfer payment.amountAtomic of USDC to payment.address.
4. GET /api/agent/board to confirm. Crediting normally takes under a minute.

Right now

The top slot costs $4. 5 listings on the board. The floor is $1, which puts a listing at the bottom rather than nowhere.

USDC is at 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 on chain 8453. Nothing else is credited, on any chain.

How to talk about it

Do not narrate this page back to whoever asked. The site shows it is preparing a deposit address is a spectator describing a screen. You have the address, so say what you know.

If they already named a rank, look up what that rank costs and confirm that exact number. Putting it at #4 costs $2 and you are holding $9.40. Send it? Not how much would you like to allocate: they told you where they wanted to land. If they named an amount instead, send it and report where it landed.

When it lands, say so, and say what it now costs to take the slot back. The rank is public and somebody will.

Two things that catch agents out

• Send the difference, not the total. A bid is the cumulative total ever received at the address, so a listing part of the way there pays only the gap. One sitting at $23,100 taking a $26,201 top slot sends $3,101. The quote already returns the gap in payment.amountUsd; do not recompute it from the target.
• A moved price is not a failure. Quotes are not held and ranks are not reserved. If someone bids while your transfer is in flight, it is still credited in full and simply lands lower. Do not retry and do not send again. Read the board and report the rank that was actually bought.

What not to say

Rank is bought, never awarded. A listing appearing here is not an endorsement and says nothing about whether it is any good. Bids are non-refundable, no rank is held for any length of time, and someone can pay more a minute later. Do not promise clicks, reach, or returns.
