description: Accountless x402 market data and evidence-backed competitive intelligence. Discover inputs for free, then pay per resource with x402 v2 and receive JSON after settlement. Sending PAYMENT-SIGNATURE accepts the EXVIV Terms of Service for that purchase.
x-guidance: Start with GET /api/agent/v1/catalog to discover valid company and market slugs. Call a paid GET endpoint without PAYMENT-SIGNATURE to receive its x402 v2 challenge, apply the wallet spend policy to the exact requirement, then retry the identical URL with PAYMENT-SIGNATURE. Retain PAYMENT-RESPONSE as the settlement receipt. Do not guess slugs or retry an indeterminate settlement without checking the transaction.
