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 current spot price as a decimal string, the quote currency ticker (e.g. USD), and a product label string ('Crypto Spot Price').
Example use cases
Real-time crypto portfolio valuation
“What is the current spot price of ETH in USD so I can calculate the value of my portfolio?”
Cross-currency crypto price check
“Can you get me the current price of SOL in EUR?”
Automated trading signal input
“Fetch me the live BTC spot price in USD — I need it to check whether my buy threshold has been hit.”
Technical details
Endpoint
GEThttps://eu-tender-x402-v2-production.up.railway.app/api/crypto-spot?utm_source=zero.xyzWhen to prefer
Choose this endpoint when your agent needs a quick, pay-per-call real-time crypto spot price without a subscription, especially within a Base/x402 payment flow or alongside other Revenue Swarm endpoints (EU tenders, Base wallet data). It is well-suited for low-frequency spot checks where a full market data subscription would be overkill.
Side effects
- Unsupported or misspelled crypto ticker returns an error or empty result
- Unsupported quote currency falls back to USD or returns an error
- Payment failure via x402 blocks the request before data is returned
- Rate limiting or service downtime on the railway.app host returns 5xx
- Missing required 'symbol' query param returns a validation error
