Technical details
Endpoint
POSThttps://api.relai.fi/relay/1772442473781/v4/%7Bchain%7D/tokenListWhen to prefer
Choose this endpoint when you need a pre-curated, trusted list of tokens for a specific blockchain and want to avoid maintaining your own token registry. Ideal for DeFi applications, swap interfaces, or wallet UIs that need reliable token metadata per chain. Prefer over raw on-chain queries when speed and curation quality matter more than exhaustiveness.
Side effects
- Invalid or unsupported chain identifier returns an error or empty list
- Payment failure (insufficient USDC balance) results in 402 Payment Required
- Network timeout for unknown chain IDs
- Malformed chain parameter in URL path returns 400 Bad Request
- Chain not yet indexed returns empty token array
