Costs $0.01 USDC per call via x402 payment protocol.

Technical details
Endpoint
GEThttps://obol-x402.fly.dev/v1/price/SOLWhen to prefer
Choose this endpoint when you need a trustless, cryptographically verifiable SOL/USD spot price that is cross-checked across two major exchanges (Coinbase and Kraken). Ideal for AI agents, trading bots, or audit pipelines that require tamper-proof price data with built-in divergence detection. Prefer over generic price APIs when non-repudiation and multi-exchange validation matter.
Side effects
- Exchange API unavailability: if Coinbase or Kraken are unreachable, the price feed may fail or return partial data
- Payment failure: if x402 payment of 0.01 USDC is not completed, endpoint returns 402 Payment Required
- Network timeout: fly.dev hosting latency may cause occasional delays or timeouts
- Signature verification failure: if the public key at /.well-known/obol-pubkey is unavailable, independent verification is blocked
