How this service works
Four x402-paid agent utilities: safe JSON Patch evaluation, multi-source crypto price consensus, normalized Polymarket movers, and deterministic JSON repair/canonicalization.
Output
Returns a JSON object with a timestamp, per-asset breakdown including per-source quotes (Coinbase, CoinGecko, Kraken), a computed median consensus price in USD, spread in basis points, min and max prices, source count, the aggregation methodology, and a list of any assets that were unavailable.
Example use cases
Pre-trade price sanity check
“Before I execute this BTC trade, can you pull the consensus price across Coinbase, CoinGecko, and Kraken and tell me if there's any meaningful spread I should be aware of?”
DeFi portfolio valuation
“I need the current consensus USD prices for BTC, ETH, and SOL from multiple sources so I can calculate my portfolio's total value — make sure you include the spread so I know how reliable the numbers are.”
Exchange discrepancy alert
“Check the current prices for ETH and SOL across all available sources and let me know if the spread in basis points is unusually wide — I'm looking for signs of price discrepancy between exchanges.”
Technical details
Endpoint
POSThttps://patch-guard-api.me-e51.workers.dev/v1/crypto-price-consensusWhen to prefer
Use this endpoint when you need a trustworthy, multi-source cryptocurrency price rather than a single-exchange quote — ideal for any scenario where price accuracy, cross-exchange consistency, or manipulation resistance matters. Prefer it over single-source price APIs when building trading logic, portfolio valuation, or any agent workflow where a single compromised or stale feed would cause downstream errors. Supports only BTC, ETH, SOL, and USDC.
Side effects
- Fewer than two sources available for an asset — consensus cannot be computed, asset listed in unavailableAssets
- Invalid or unsupported asset symbol submitted — validation error
- Network timeout fetching one or more price sources — partial results or degraded consensus
- Request with empty or malformed assets array — schema validation error
