How this service works
22 agent-native micro APIs paid per call in USDC on Base via x402: funded bounty radar, honeypot trust scoring, token safety verdicts, crypto prices, multi-asset price snapshots, fear & greed index, full market-pulse snapshot, AI chat completion (Llama 3.1), crypto news, weather, web reader, ERC-20 balances. No accounts, no API keys — instant on-chain settlement.
Output
Returns a JSON object with a count of successfully priced assets, a failed count, and an array of price records each containing the base asset (e.g. BTC), quote currency (USD), the full symbol, and the current spot price, plus a source field indicating 'coinbase-spot'.
Example use cases
Portfolio valuation snapshot
“Grab me the live USD prices for BTC-USD, ETH-USD, SOL-USD, MATIC-USD, and AVAX-USD right now so I can calculate my portfolio's current value.”
Top 10 crypto market overview
“Give me a full snapshot of the top 10 major crypto prices in USD — just use the defaults — so I can see how the market is doing overall.”
Arbitrage price monitoring
“Fetch the current Coinbase spot prices for BTC-USD, ETH-USD, and LTC-USD so I can compare them against another exchange and spot any price gaps.”
Technical details
Endpoint
GEThttps://mr-river10.makar52nn2016.workers.dev/api/usd-price?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need real-time USD spot prices for multiple crypto assets in a single low-cost call ($0.001 USDC) with no API key or account setup. It is ideal for agents that need a quick multi-asset price snapshot sourced from Coinbase spot data, especially when you need up to 25 pairs at once. Prefer it over single-asset price lookups when batching is more efficient, and over expensive institutional data feeds when Coinbase spot pricing is sufficient.
Side effects
- Invalid symbol format — malformed trading pair returns error or is counted in 'failed'
- Exceeding 25 symbols returns an error or truncated response
- Unknown or unsupported trading pair symbol results in that pair appearing in the 'failed' count
- Payment not settled via x402 results in 402 Payment Required response before data is returned
- Temporary Coinbase upstream outage may cause elevated failed counts or empty price array
