How this service works
Chainlink For Agents: submit a signed operation payload.
Output
Returns confirmation that the signed operation has been accepted and submitted, along with a status or receipt indicating whether the operation was successfully dispatched into the Chainlink agent infrastructure.
Example use cases
Finalize on-chain oracle data request
“I've already constructed and signed my Chainlink operation for fetching the ETH/USD price feed — can you submit the signed payload with operation ID 'op_eth789' and signature '0xabcdef12…' to the Chainlink agent network so it gets executed on-chain?”
Broadcast signed Data Streams payload
“My trading bot just signed a Data Streams operation with ID 'op_ds456' and signature '0x1a2b3c4d…' — please dispatch it to the Chainlink agent infrastructure so the stream data pull gets triggered trustlessly.”
Complete pending cross-chain agent operation
“I have a signed cross-chain operation ready to go — operation ID is 'op_xchain321' and the signature is '0xfeed9876…'. Submit it to agents.chain.link so the operation is finalized and executed through the Chainlink agent network.”
