How this service works
12 pay-per-call HTTP APIs settled in USDC on Base via x402 v2. No API keys, no accounts, no signup — $0.0005–$0.0020 per call. Includes a locally hosted 27B LLM endpoint.
Output
A JSON object mapping each requested cryptocurrency ID (e.g. 'bitcoin', 'ethereum') to an object containing its price in the requested fiat currency (e.g. {'bitcoin': {'usd': 83000}, 'ethereum': {'usd': 2600}}).
Example use cases
DeFi portfolio valuation agent
“Get me the current USD prices for bitcoin, ethereum, and solana so I can calculate my portfolio value.”

“Check the current price of ethereum in USD and let me know if it's above $3000.”
Agent expense settlement in crypto
“What's the live bitcoin price in USD? I need to convert a $500 payment into the right amount of BTC.”
Technical details
Endpoint
GEThttps://sableforge.servehttp.com/api/price?utm_source=zero.xyzWhen to prefer
Choose this endpoint when your agent needs pay-per-call crypto price lookups with no API key or account setup, particularly in autonomous agent workflows using the x402 micropayment protocol on Base. Ideal for agents that need to fetch prices for one or a few coins ad hoc, without committing to a subscription.
Side effects
- Unknown coin ID returns empty or error response
- Invalid vs_currencies value may return no data
- Payment failure via x402 protocol blocks the call
- Service unavailable if self-hosted server is offline
- Rate limits or upstream data source outages
