Authoritative pricing: agents should always read the live catalog immediately before paying. The catalog declares whether commerce is enabled, which inputs are valid, and which network will settle the purchase.
Agent interface
Discovery, payment, and delivery in five HTTP steps.
- Read the instructions.
Start at /llms.txt, then fetch the free machine catalog and OpenAPI 3.1 contract.
- Choose a valid resource.
Select a reviewed company slug or market from the catalog instead of guessing an input.
- Receive the payment requirement.
Call the resource without payment. EXVIV responds with HTTP 402 and a base64-encoded
PAYMENT-REQUIREDheader. - Apply the wallet’s spend policy.
If approved, sign the exact requirement and repeat the same request with
PAYMENT-SIGNATURE. - Receive JSON and the receipt.
After successful settlement, EXVIV returns the purchased intelligence and
PAYMENT-RESPONSEwith the transaction result.

Machine-readable does not mean unreviewed.
EXVIV’s paid interface exposes reviewed public changes and reviewed pricing snapshots. It excludes raw page captures, pending observations, dismissed changes, and unreviewed pricing extraction.
No invented outcomes
The response separates observed evidence from interpretation and does not claim a commercial result that was never measured.
Indeterminate means stop
If settlement does not return a final result, the agent should inspect the transaction before attempting another payment.
Purchase terms are explicit
Sending the payment signature accepts the terms for that purchase; refund and duplicate-payment handling are published.
Common questions
What an agent needs to know before it pays.
Does the buyer need an EXVIV account?
No. The signed payment is the purchase credential. These endpoints do not require cookies, sessions, subscriptions, or an EXVIV API key.
What does the buying agent need?
An x402-compatible wallet with the required USDC, the supported network, and a spend policy that approves the advertised price.
Can the price change between requests?
The live 402 requirement is authoritative for that attempt. The buyer must sign the exact amount, asset, network, and recipient it received.
What if payment settles but delivery fails?
Retain the transaction, request URL, network, and response. EXVIV publishes redelivery and refund handling in its purchase policy.
Give the agent a contract, not a checkout form.
Start with the free catalog, import the OpenAPI description, and let the wallet decide whether the evidence is worth the posted price.
