Technical details
Endpoint
POSThttps://omni-api-cyan.vercel.app/api/crypto/address/tokensWhen to prefer
Use this endpoint when you need a quick, pay-per-call token holdings lookup for a specific blockchain address without setting up a dedicated node or indexer. Ideal for multi-chain portfolio checks, due diligence flows, or airdrop eligibility verification where spinning up a dedicated blockchain data service is overkill.
Side effects
- Invalid or malformed wallet address returns an error or empty result
- Unsupported chain not covered by OmniAPI returns no data
- Rate limiting or payment failure (x402) blocks the request
- Address with no token holdings returns an empty token list
- Network timeout from the underlying blockchain data provider
