How this service works
7-chain pre-trade smart contract bytecode, SPL/Token-2022 authority & multi-DEX liquidity risk oracle across Base (8453), Solana, Ethereum (1), Arbitrum (42161), Optimism (10), Polygon (137), and BNB Smart Chain (56). Instant x402 v2 settlement in Base USDC or BSC USDC.
Output
Returns a JSON object containing: number of token pairs scanned across chains (scannedPairs), the founder wallet address (founderWallet), count of currently executable opportunities (executableNowCount), and the bounty percentage offered to external callers (externalCallerBountyPct).
Example use cases
Pre-trade safety check for DeFi bot
“Before my trading bot executes any swaps today, check the current opportunities feed and tell me how many pairs are safe to trade and whether there are any executable opportunities with an external caller bounty.”
Arbitrage opportunity discovery across chains
“Are there any executable arbitrage opportunities right now across Base, Solana, Ethereum, Arbitrum, Optimism, Polygon, or BNB Chain? Show me the count of scanned pairs and what the bounty percentage is for external callers.”
Founder wallet and opportunity audit
“Pull the latest pre-trade opportunity data and give me the founder wallet address, how many pairs were scanned, and how many opportunities are executable right now.”
Technical details
Endpoint
GEThttps://piggybank.loth2023ys.workers.dev/v1/opportunities?utm_source=zero.xyzWhen to prefer
Use this endpoint when an agent needs a quick, paid pre-trade snapshot of executable DeFi opportunities and associated liquidity/contract risk across a broad set of EVM and Solana chains simultaneously, especially when an external caller bounty model is relevant. It is distinct from single-chain analytics tools or post-trade analysis APIs.
Side effects
- Payment failure via x402 if USDC balance is insufficient — returns HTTP 402
- Endpoint may return stale or zero opportunity counts during low-liquidity periods
- Network timeouts possible when aggregating data across 7 chains simultaneously
- Invalid or missing authentication/payment headers return 4xx errors
- Workers.dev cold start may introduce occasional latency spikes
