Opportunity 3: Same question again, axp.one MVP

1. The moment

The app offered one Sponsored slot beside its answer. Only these fields reach the exchange.

TopicCrypto wallet toolsCoarse intent only; no user profile

Floor price0.001 USDCTest USDC; the lowest bid the app accepts

Must haveCrypto storage

Nice to haveHardware walletOffline key storageEthereumSolana

Same question, fresh answer

The app asked the same question as opportunity 1 and got a new completion: the answer is not cached. Both hashes are in the Inspector.

The answer on the left was written by the app's own model with no advertiser material. The Sponsored slot under it is separate.

2. Who may compete

A rule in code decides who can enter the auction: a campaign must declare every required capability.

Campaign	crypto storage	Ruling
ClearVault	✓Declared	ExcludedFrequency cap: placed twice this session
KeyForge	✓Declared	May compete
LeatherGuard	✕Not declared	ExcludedMissing crypto storage

An excluded agent was still asked here; its answer could never count. Funding is checked at auction time, and history never adds a capability.

3. What each agent was shown

Each agent got its own packet of ContextHint history (contexthint.com): past prompts, the ads that appeared beside them, and inferred targeting hints.

ContextHint had seen this exact question before

It appeared next to an ad from Mercari. Agents get that history as evidence. Real brands are past observations, not bidders.

4. What each agent decided

Decided with Jev, a judgment model. Each agent answers relevance (does the approved card fit?), buying intent (is the person ready to choose?) and whether its card fits, each with Jev's own confidence. Levels run from 0 to 3.

Excluded by rule (missing crypto storage); its agent was still asked (its answer could never count) and chose no fitting creative. History never adds a capability.

Only the answer with history was asked here

Only paired questions also ask without history. KeyForge's intent score was 2.49, so level 2.

5. Auction

Code turns levels into a bid: a share of the campaign's max bid. Highest bid wins; the model never names a price.

KeyForge was the only bidder and paid its own bid, 0.003 USDC.

A rule kept a bidder out. Agent said bid. Exchange did not admit it.

ClearVault had already been placed twice in this session, so the frequency cap kept it out of the auction (no bid, no amount). KeyForge, the only admitted bidder, won at 0.003 USDC with relevance 3, intent 2.

6. Award, not a charge yet

The winner's card is reserved for the slot. Budget is held; nothing is owed until the app proves delivery.
