How this service works
Open x402 funding rail: POST target+amount or provision:true+label+amount; pay 0.25% (min $0.001, max $0.25) via x402 on Base or Solana; net forwarded on the same chain. Optional managed child wallets (CDP, Base only). Optional public receipt when storage is configured.
Output
Returns a JSON object confirming the payment was received, including: the receipt ID and URL for auditing, the gross amount paid (net + 1% fee), the fee amount, the net deposit amount forwarded, the target wallet address, the forward settlement status, and a boolean indicating whether a new child wallet was provisioned.
Example use cases
Top up autonomous trading agent
“Fund my trading agent at 0xAbC123...def456 with $200 USDC on Base — add a memo saying 'weekly trading budget'.”
Provision new managed child wallet
“Create and fund a brand-new managed wallet for my data-scraping agent — label it 'scraper-agent-1' and deposit $25 USDC into it.”
Refill low-balance agent mid-workflow
“My order-execution agent at 0x1234...5678 is running low on funds — send it $10 USDC right now so it can keep running.”
Technical details
Endpoint
GEThttps://deposit.now/api/depositWhen to prefer
Choose this endpoint when an AI agent needs to programmatically fund an EVM wallet or spin up a new managed CDP child wallet with USDC on Base, particularly within x402-native agentic workflows where no API key is desired. Prefer it over manual wallet transfers or centralized fiat on-ramps when the caller already holds USDC on Base and needs a low-friction, receipt-generating funding rail with a stable 1% fee model. It is especially well-suited for multi-agent architectures where sub-agents need their own funded wallets provisioned on demand.
Side effects
- Insufficient USDC balance in the calling agent's wallet to cover amount + 1% fee — payment rejected at x402 layer
- Missing or invalid target EVM address when provision is false — request rejected
- provision:true sent alongside a target address — conflicting parameters cause request failure
- label not provided when provision:true and no Idempotency-Key set — required field missing error
- Amount below $0.01 or above $100,000 — out-of-range validation error
- x402 payment handshake failure — network or facilitator unavailability
- memo exceeding 256 characters — validation error
