## When to prefer this

Choose this endpoint when you need a lightweight, pay-per-call USD spot price for a token without managing API keys. It is ideal for AI agents operating autonomously on Base that need real-time crypto prices as part of a workflow, especially when CoinGecko's free tier suffices and Alchemy serves as a reliable fallback. Prefer it over raw CoinGecko or Alchemy direct calls when you want a unified x402-compatible interface billed in USDC.

## Known failure modes

- Unknown token id or symbol returns a 404 or empty result
- Invalid contract address format (must match ^0x[0-9a-fA-F]{40}$) returns a 400 validation error
- Unsupported chain parameter results in an error or no data
- Rate limits on underlying CoinGecko or Alchemy APIs may cause transient failures or delays
- Payment failure via x402 (insufficient USDC balance) results in a 402 response blocking the request
- Stale or delayed pricing data if upstream providers are lagging

## How this service works

One pay-per-call API for AI agents: optimization, AI, research, on-chain data, and automation — all settled in USDC on Base via x402. Discover via MCP and Bazaar, estimate free, pay per call. No API keys, no signup.

## Output

Returns the current USD spot price for the requested token or coin, identified by CoinGecko id, contract address, or chain. The response includes the numeric price value in USD, sourced from CoinGecko on the free tier or Alchemy when needed.
