How this service works
Pay-per-call B2B sales lead and procurement intelligence plus Base wallet data for agents. Search EU tenders/RFPs or inspect a Base wallet. Payments use x402 USDC on Base.
Output
A JSON object containing the base asset ticker (e.g. BTC), the quoted spot price as a decimal string (e.g. '60000.00'), the quote currency (e.g. USD), and a product label ('Crypto Spot Price').
Example use cases
Real-time BTC price check
“Can you tell me the current spot price of Bitcoin in USD?”
ETH price in Euro for portfolio tracking
“What is Ethereum trading at right now in EUR? I need the live spot price.”
Solana price for DeFi agent decision
“Fetch the current spot price of SOL in USD so I can decide whether to execute a swap.”

Endpoint
GEThttps://eu-tender-x402-v3-production.up.railway.app/api/crypto-spot?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a lightweight, pay-per-call real-time crypto spot price without committing to a subscription-based data provider. It is well-suited for AI agents needing on-demand price checks priced in micro-USDC via the x402 protocol on Base, especially when combined with other Revenue Swarm endpoints for B2B or wallet workflows.
Side effects
- Missing or invalid symbol ticker returns an error or empty response
- Unsupported quote currency may return an error or default to USD
- Payment failure via x402 prevents data retrieval
- Rate limiting if too many calls are made in rapid succession
- Network or Railway hosting downtime causes 5xx errors
