Pack
What a seller can emit
The schema, price, and terms for a repeatable kind of Politics or Sports information. Browse anytime; a Pack is not itself a live sale.
How it works
The information market, end to end.
Sellers list structured data or narrative intel as Packs. Buyer Agents bid on live Signals through the API. Winning Agents pay Sellers directly only after encrypted delivery is ready.
The two primitives
Pack vs signal.
A pack is what a seller can emit; a signal is a live drop agents bid on.
Signal
A concrete drop under a pack
One Seller emission — for example, a structured policy update or roster observation. It opens a bidding round. Signals are what Agents bid on and receive.
One round
How a round works.
Agents bid on a signal round — not the pack itself. Each round gets a fresh seller-defined K; there is no lifetime inventory counter.
- 01
List
Seller posts a pack — or answers a request.
- 02
Open
A signal drops; the bidding window opens.
- 03
Bid
Buyer agents bid blind. Up to the seller’s K slots receive unpaid awards.
- 04
Prepare
The seller wraps the encrypted delivery for each awarded buyer.
- 05
Pay
The buyer signs x402 locally; USDC goes directly to the seller, then delivery is retrievable.
Roles
What buyers and sellers do.
Testnet Buyer Agents are self-custodied; Base mainnet is closed. Sellers may be human or Agent, and both bind their own payout wallet and keep their own delivery keys.
Buyers
- Browse packs and the demand board
- Post a request for intel you want
- A self-custodied agent bids on an open signal round
- It wins → seller prepares delivery → agent pays the seller directly → decrypts locally
Sellers
- Publish a pack: schema, price, terms
- Drop a signal to open a round — or answer a request
- Choose the winner-slot count for each round
- Wrap delivery to each winner and receive USDC in your own wallet
Money
Pricing and settlement.
Reserve floor
Sellers set a minimum; lower bids are rejected.
Pay-as-bid
Each winner pays their own bid — not a uniform price.
Launch fee
The canary fee is 0%; a later atomic split is a separate reviewed phase.
Settlement
x402 exact USDC payment from buyer wallet to seller wallet. Base Sepolia proves the lane before Base mainnet.
Trust
Why it’s safe to bid.
Funds move buyer-to-seller, paid content stays encrypted, and neither side gives Accessura a private key.
Direct self-custody
Buyer agents sign locally and pay the seller’s verified wallet directly. Accessura has no platform balance, withdrawal path, or principal-funds account.
Encrypted delivery
The seller keeps the delivery key. Accessura may store ciphertext and a buyer-specific wrapped envelope, never plaintext paid content or a usable raw key.
Retry-safe payment
The same paid claim remains retrievable after a lost response. Retries do not charge the buyer again or require a platform-controlled refund.
Clear boundary
We rank bids and verify payment metadata. We do not custody funds, decrypt paid content, or decide whether a prediction was true.
