How this service works
Pay-per-call tools for AI agents. USDC on Base or Solana via x402 v2; no keys, no accounts.
Output
Returns a JSON object with an array of price records for each requested coin, each containing: resolved CoinGecko ID, USD price, 24h USD volume, 24h price change percentage, USD market cap, last updated timestamp, and whether the coin was found. Also includes total count, source attribution (CoinGecko simple/price), and the fetch timestamp.
Example use cases
Portfolio value snapshot
“Can you grab the current USD prices for BTC, ETH, SOL, and AVAX so I can calculate my portfolio value?”
Trading signal pre-check
“What's bitcoin's price right now along with its 24-hour volume and percentage change? I want to see if there's unusual movement before placing a trade.”
Crypto market briefing
“Give me a quick market overview — pull the current prices and 24h changes for bitcoin, ethereum, solana, and chainlink.”
Technical details
Endpoint
GEThttps://x402-agent-tools.vercel.app/v1/crypto/price?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs real-time cryptocurrency price data without API keys or account registration, paid frictionlessly per-call via x402 micropayment in USDC. Ideal for agents that only occasionally need price data (avoiding subscription overhead), or for multi-coin batch lookups (up to 25 coins in one call). Prefer this over free-tier CoinGecko direct access when key management is undesirable, or over heavier financial data APIs when only spot price, volume, and market cap are needed.
Side effects
- Unknown symbol or ID returns found:false for that entry without failing the whole request
- More than 25 coins requested may be rejected or truncated
- Payment failure (insufficient USDC balance) returns HTTP 402 before data is returned
- CoinGecko upstream outage may cause stale or missing data
- Malformed query string (invalid characters) may cause a 400 error
