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 — one per requested coin — each containing the resolved coin ID, current USD price, 24h USD volume, 24h percentage price change, USD market cap, and last-updated timestamp. Also includes total count of coins found and the data source (CoinGecko simple/price) plus a fetchedAt timestamp.
Example use cases
Portfolio snapshot at market open
“Pull the current USD prices and 24-hour change for btc, eth, sol, and bnb so I can see how my portfolio is doing this morning.”
Crypto price alert trigger
“Check the current price of ethereum — if it's dropped more than 5% in the last 24 hours I want to know the exact figure and volume.”
DeFi yield comparison research
“What are the current prices and market caps for solana, avalanche, and near so I can compare their relative sizes before deciding where to deploy liquidity?”
Technical details
Endpoint
GEThttps://api.gptshopltd.com/v1/crypto/price?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs fast, no-account-required real-time crypto price data paid per-call with USDC via x402 — ideal for autonomous agents that need on-demand pricing without API key management. Prefer it over free tiers when you need pay-as-you-go access with no rate-limit negotiation, or when the agent operates in a crypto-native payment context already using x402.
Side effects
- Unknown coin symbol or CoinGecko ID returns found:false for that entry without erroring the whole request
- Requesting more than 25 coins in a single call may be rejected or silently truncated
- CoinGecko upstream downtime may cause stale or missing data
- Malformed comma-separated query string results in a 400 or empty response
- Payment failure (insufficient USDC balance) results in HTTP 402 before the data is returned
