curl -X POST https://api.glianalabs.com/v1/tools/swap-build \
  -H 'content-type: application/json' \
  -d '{"chain":"base","from":"USDC","to":"ETH","amount":"10","address":"0x7662E00f8Ab4C362166e1FF649Ff6c2A638c80AD"}'

When to use it

Non-custodial: GlianaAI never holds keys or funds, and nothing happens until the caller signs. Use when an agent has decided to trade and needs a ready transaction. Returns the EVM transaction (to, data, value, gasLimit) or a base64 Solana transaction, an ERC-20 approval transaction when one may be needed, receive and receive_min, value_lost_pct and fees. The per-call price buys the transaction; a GlianaAI service fee, shown as service_fee_pct, already deducted from receive and counted in value_lost_pct, is taken on-chain only when it is signed and sent. Refuses for free when value lost exceeds max_value_lost_pct (default 3) or no route exists. Check the amounts before signing.

What it costs

$0.0050 per successful call — flat, with no plan, minimum or monthly fee. A call that fails validation is refused before it runs, so it is never charged.
