How this service works
Get real-time token price, market cap and more. Pass an EVM chain plus ERC-20 contract address; returns current price (USD or any quote currency), 24h/7d/30d percentage changes, market cap, fully diluted valuation, 24h volume, all-time high/low, total / circulating / max supply, and basic community stats. Cached server-side for ~7 minutes for low-cost agent lookups.
Output
Returns a JSON object containing the token's current price in the requested quote currency, percentage price changes over 24h, 7d, and 30d windows, market cap, fully diluted valuation, 24h trading volume, all-time high and low prices, total/circulating/max supply figures, and basic community statistics. Data is cached server-side for approximately 7 minutes.
Example use cases
DeFi portfolio price check
“Can you pull up the current price, market cap, and 24h/7d price changes for the token at 0x6B175474E89094C44Da98b954EedeAC495271d0F on Ethereum in USD?”
New token due diligence
“I'm looking at a token on Base at address 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 — what's its fully diluted valuation, circulating supply, and all-time high right now?”
Cross-chain price comparison
“Get me the current price in ETH for the token at 0x2791Bca1f2de4661ED88A30C99A7a9449Aa84174 on Polygon so I can compare it against the same token on Arbitrum.”
Technical details
Endpoint
POSThttps://x402.blocknotify.com/v1/token-priceWhen to prefer
Choose this endpoint when you need comprehensive token market data — price, market cap, supply, volume, and historical changes — for a known ERC-20 contract address on a supported EVM chain (Ethereum, Polygon, Arbitrum, Optimism, Base). Prefer this over on-chain RPC calls when you want aggregated market data (not just on-chain state) and when the ~7-minute cache latency is acceptable. Use this instead of general crypto price APIs when you already have the contract address and want structured multi-metric output in a single call.
Side effects
- Invalid or non-ERC-20 contract address returns an error or empty result
- Unsupported chain value outside the allowed enum causes a validation error
- Token with no price feed or very low liquidity may return null/missing price fields
- Unsupported quote currency may return an error or fall back to USD
- Payment failure (insufficient USDC balance) blocks the request under x402 protocol
