Overview

Returns one ready-to-sign selfBatchDeposit transaction on the strategy's chain, covering local vault deposits plus per-remote-chain CCTP burns. The matching intent (kind deposit) is written server-side; do not post an intent separately. No auth; no request body (the id is in the path).

Strategy must be pending_setup (top-ups are not supported).

Timing: expiresAt is an advisory ~1h plan-freshness bound. The intent itself has a 30-day TTL; regenerating an unchanged plan within it returns the same intentId, and regenerating after expiry or fulfillment mints a new one. A strategy that has never received a deposit is purged about one hour after it was last touched, taking its intent with it; calling this endpoint refreshes that hour. If signing takes longer than an hour (e.g. a multisig), regenerate at least hourly until the transaction is broadcast.

Approve vault share tokens and USDC before calling: live allowances affect vault selection, and approvalsNeeded reflects what is still missing.

Submit the returned data verbatim (re-encoding breaks intent attribution) and use gasHint as the gas limit (wallet re-estimates can run out of gas).

Endpoint

POST https://earn-api.quicknode.dev/functions/v1/api/v1/strategies/{id}/calldata/deposit

Authorization

Include the published apikey header. This endpoint is public and does not require a SIWE signature.

Rate limits

This operation belongs to the calldata rate-limit bucket. It allows 10 requests per 60 seconds, keyed by strategy+ip. A coarser limit of approximately 30 requests per 60 seconds also applies per IP across deposit, withdrawal, and claim calldata requests.

Parameters

Parameter	Location	Type	Required	Description
id	path	string	Yes	Strategy UUID.

Request body

Deposit calldata request body. Public (no SIWE). The deposit endpoint takes no parameters, so send no body or an empty JSON object ({}).

Example request

curl --request POST \
  --url 'https://earn-api.quicknode.dev/functions/v1/api/v1/strategies/<PENDING_STRATEGY_ID>/calldata/deposit' \
  --header 'Accept: application/json' \
  --header 'apikey: <EARN_PUBLIC_API_KEY>' \
  --header 'Content-Type: application/json' \
  --data '{}'

transactions[].description	string	Yes	Human-readable transaction summary.
transactions[].gasHint	string | null	Yes	Recommended gas limit, or `null` when it cannot be estimated.
transactions[].gasHintReason	string	No	`approvals_required` or `estimation_failed` when `gasHint` is `null`.
approvalsNeeded[].chainId	integer	Yes	Chain where approval is required.
approvalsNeeded[].token	string	Yes	Token contract requiring an allowance.
approvalsNeeded[].spender	string	Yes	Quicknode Earn proxy address.
approvalsNeeded[].currentAllowance	string	Yes	Current allowance in token base units.
approvalsNeeded[].requiredAllowance	string	Yes	Required allowance in token base units.
approvalsNeeded[].tx	object	Yes	Ready-to-sign token approval transaction.
approvalsNeeded[].tx.to	string	Yes	Token contract receiving the approval call.
approvalsNeeded[].tx.data	string	Yes	ABI-encoded approval calldata.
approvalsNeeded[].tx.value	string	Yes	Native-token value, normally `"0"`.
plan.totalUsdc	string	Yes	Total allocated USDC as a six-decimal base-unit string.
plan.vaults	array<string>	Yes	Local-chain vault addresses.
plan.amounts	array<string>	Yes	Base-unit amounts aligned with `plan.vaults`.
plan.burns	array<object>	Yes	Combined CCTP burns for remote chains.
plan.burns[].destDomain	integer	Yes	CCTP destination domain.
plan.burns[].mintRecipient	string	Yes	Bytes32-padded mint recipient.
plan.burns[].destinationCaller	string	Yes	Bytes32-padded destination caller.
plan.burns[].amount	string	Yes	Burn amount in USDC base units.
plan.burns[].maxFee	string	Yes	Maximum CCTP fee in base units.
plan.burns[].minFinalityThreshold	integer	Yes	Minimum CCTP finality threshold.
plan.burnVaultBreakdown	array<array<object>>	Yes	Destination vault allocations aligned with `plan.burns`.
plan.burnVaultBreakdown[][].vault	string	Yes	Destination vault address.
plan.burnVaultBreakdown[][].amount	string	Yes	Vault allocation in USDC base units.
plan.burnVaultBreakdown[][].name	string	Yes	Destination vault name.
plan.burnVaultBreakdown[][].apy	number	Yes	Destination vault APY percentage.
plan.apys	object	Yes	Map of vault keys to APY percentages.
plan.vaultNames	object	Yes	Map of vault keys to vault names.
plan.chainIds	object	Yes	Map of vault keys to chain IDs.

HTTP responses

Status	Description
200	One deposit transaction, approvals needed, plan transparency, and an advisory expiry.
400	One of: the strategy is not `pending_setup` (`invalid_state`); no eligible vaults (`no_eligible_vaults`); gas estimation failed (`gas_estimation_failed`, the tx would revert, usually unfunded or unapproved); or a malformed JSON body (`invalid_request`).
404	Resource not found.
429	Rate limit exceeded. `Retry-After` (seconds) tells you when to retry. Reads, feedback, and push writes are keyed per IP; create/update/delete are keyed per wallet+IP; deposit/withdraw/claim calldata is keyed per strategy+IP.
500	Internal error, or `burn_route_unavailable` when a required remote chain has no CCTP burn route configured.
503	The hide list could not be loaded (`hide_lookup_failed`, fails closed).
