Cross-chain price gap finder returning raw arbitrage opportunities across 7+ EVM chains and Solana.
What it does
This endpoint scans multiple blockchain networks for cross-chain token price discrepancies and returns raw data on profitable routing opportunities. It is part of the Einstein AI x402 API suite, which provides blockchain intelligence powered by Bitquery data. The endpoint accepts optional parameters for chain selection (base, ethereum, bsc, arbitrum, polygon, optimism, solana), result limits (up to 500), and time periods (1h to 30d), returning structured JSON with price gap data.
Payment is handled via the x402 protocol at $1.00 per request, payable in USDC on Base (0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913), USDC on Solana, or BTC via Lightning Network (~1,310 sats). The "/raw" suffix indicates this endpoint returns unprocessed query results without AI-generated analysis, distinguishing it from the related arbitrage scanner endpoint which includes AI interpretation at $1.15 per call. No API keys are required; authentication is purely payment-based via the X-PAYMENT header.
The endpoint is live and returning a valid x402 payment challenge. It is part of a broader suite of 20+ blockchain intelligence endpoints covering market data, whale tracking, launchpad monitoring (Pump.fun, Zora), security audits (rug pull detection, MEV detection), and DeFi analytics. Supported chains vary by endpoint but this one covers base, ethereum, bsc, arbitrum, polygon, optimism, and solana.
Capabilities
Use cases
- —Automated trading agents scanning for cross-chain arbitrage opportunities
- —Portfolio management bots identifying mispriced tokens across DEXes
- —DeFi dashboards displaying real-time price gaps between chains
- —Research tools analyzing cross-chain market efficiency
- —MEV strategy development using raw price gap data
Fit
Best for
- —AI agents needing programmatic cross-chain price gap data without AI interpretation
- —Automated arbitrage bots that process raw data with their own logic
- —Developers building multi-chain DeFi tools who want pay-per-use pricing
Not for
- —Users wanting AI-interpreted arbitrage recommendations (use /x402/bitquery/arbitragescanner instead)
- —Applications requiring free or subscription-based access without per-call payments
- —Single-chain-only analytics where a direct DEX API would suffice

Quality
The endpoint is live with a valid x402 402 challenge, has a full OpenAPI spec with input/output schemas, and clear pricing. However, the specific /pricegaps/raw path is not explicitly listed in the OpenAPI paths (only the arbitragescanner is), so the exact response structure is inferred from the outputSchema in the challenge and the generic BitqueryResponse schema. No actual response example with real price gap data is available.
Warnings
- —The /x402/bitquery/pricegaps/raw endpoint is not explicitly listed in the OpenAPI spec paths; its schema is inferred from the x402 challenge outputSchema and the generic BitqueryResponse schema.
- —The /api route returned a 522 (host error) during crawl, suggesting intermittent backend availability issues.
- —Response data structure for price gaps is not documented in detail — the 'result' field contents are unknown.
