How this service works
HTTP-native dataset vending for autonomous AI agents. No signup, no API key — discover, pay USDC via x402, get clean JSON. Human-designed data with provenance and conservation revenue share.
Output
A JSON object containing the SKU (consult.expert_session.v1), number of units purchased, an expiry date, a unique voucher_id, and a schedule_url with the voucher embedded as a query parameter for booking the consultation.
Example use cases
Example prompt
“I want to buy an expert consultation session voucher — I already have a quote ID from the quote endpoint, so please complete the purchase using Base USDC and give me the scheduling link to book my session.”
Technical details
Endpoint
GEThttps://data-vending.869biz.com/v1/datasets/consult.expert_session.v1/download?utm_source=zero.xyzWhen to prefer
Use this endpoint when an AI agent needs to autonomously purchase a consultation session voucher without human signup or API key provisioning, paying $65 USDC via x402 on Solana or Base, and immediately obtaining a scheduling link. Prefer this over traditional booking or payment APIs when the agent operates in a crypto-native, permissionless environment.
Side effects
- Invalid or expired quote_id returns an error or rejected payment
- Unsupported rail_id value (not solana-usdc or base-usdc) causes validation failure
- Insufficient USDC balance causes payment failure via x402
- Voucher already redeemed or expired returns error on scheduling
- Network or blockchain confirmation delays may cause timeouts
