Kyber (on-chain spot)

Category: Trading

Catalog provider: trading (Kyber is the primary on-chain swap router behind spot actions, not a separate provider filter).

Thirdfy exposes Kyber quote and swap execution through governed catalog actions such as swap, get_best_trading_quote, and execute_optimal_swap. Sponsored Kyber execution is validated on Base mainnet; other chains may be quote-only or deployment-specific.

Credential model

No Kyber API keys in Thirdfy. Execution is on-chain through validated router calldata.

Discovery

Use it

Ask your agent:

Using Thirdfy, quote a swap of 10 USDC to WETH on Base and show the route. Do not swap anything.

Kyber has no venue readiness check. The quote is the setup step: it shows the route and output before any swap.

One read. get_best_trading_quote compares routes and may pick Thirdfy, Kyber, Li.Fi or 0x:

agentRun { action: "get_best_trading_quote", params: { tokenIn: "USDC", tokenOut: "WETH", amountIn: "10", chainId: 8453 } }

thirdfy-agent run --action get_best_trading_quote --provider trading --params '{"tokenIn":"USDC","tokenOut":"WETH","amountIn":"10","chainId":8453}' --json

curl -s -X POST https://mcp.thirdfy.com/tool/agentRun \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer $AGENT_API_KEY" \
  -d '{"action":"get_best_trading_quote","params":{"tokenIn":"USDC","tokenOut":"WETH","amountIn":"10","chainId":8453}}'

The agent's policy must allow the action. If it does not, the run fails with Action "get-best-trading-quote" is not allowed and lists the allowed actions.

What to check: confirm the chain and token addresses the quote resolved, the route provider and the output amount. slippageTolerance defaults to 1%. Quote again right before a swap.

One write. The swap itself:

agentRun { action: "swap", params: { tokenIn: "USDC", tokenOut: "WETH", amountIn: "10", chainId: 8453, maxSlippage: 1 } }

thirdfy-agent run --action swap --provider trading --run-mode agent_wallet --chain-id 8453 --params '{"tokenIn":"USDC","tokenOut":"WETH","amountIn":"10","chainId":8453,"maxSlippage":1}' --estimated-amount-usd 10 --confirm-writes --json

execute_optimal_swap is an alias of swap. amountIn is in token units; pass one amount field only. A high price impact is refused unless you set allowHighImpact: true. Run thirdfy-agent preflight with the same flags to check the params before you send it.

Readiness checklist

• Correct chainId (Ethereum, Optimism, Unichain, Polygon, Base, Arbitrum per catalog).
• Slippage and token addresses match catalog param schema.
• Delegation active before delegated-user swaps.
• Preflight swap or execute_optimal_swap before live runs.
