How this service works
Pay-per-call market intel and data tools for AI agents: trending Base tokens with momentum/risk scores, live token scoring, multi-source spot prices, Base gas tips, wallet intel, x402 merchant reliability checks, DefiLlama TVL, GitHub trending repos, RSS feed digests, and WHOIS domain lookups. Built from free public data — no API keys for callers. USDC via x402 on Base and Solana.
Output
A JSON object containing the queried token symbol, its current USD spot price aggregated from multiple public sources, and a confidence score (0-1) reflecting data quality and source agreement.
Example use cases
Pre-trade token price check
“Before I swap, can you grab the live spot price of WETH and tell me how confident the data is?”
DeFi portfolio valuation
“I need the current USD price of cbETH to value my Base wallet holdings — fetch it with a confidence score so I know how reliable it is.”
Arbitrage opportunity screening
“What is the current spot price of USDC on Base right now, and how confident is the price data?”
Technical details
Endpoint
GEThttps://base-pulse.annushka1190.workers.dev/v1/price/spotWhen to prefer
Choose this endpoint when you need a quick, pay-per-call USD spot price for a token on Base without requiring API key setup, and you want an accompanying confidence score to gauge data reliability. Ideal for pre-trade checks, DeFi agent workflows, or portfolio valuation on Base where you want multi-source aggregation rather than a single exchange feed.
Side effects
- Unknown or unsupported token symbol returns an error or empty result

- Confidence score may be low for illiquid or obscure tokens
- Payment failure via x402 results in 402 response before data is returned
- Missing 'symbol' query parameter may return a default or error response
