How this service works
Fund any address with testnet money via the Coinbase faucet - USDC (1) or ETH (0.0001) on Base Sepolia, USDC (1) or SOL on Solana devnet - everything an agent needs to rehearse the complete x402 payment loop safely before moving real money. A tenth of a cent buys a full testnet dollar. Limits: 2 drips per address per day; CDP enforces its own rolling caps on top.
Output
A confirmation that the specified testnet tokens (1 USDC, 0.0001 ETH, or SOL) have been sent to the provided address on the requested network, typically including transaction details or a success status.
Example use cases
Example prompt
“Fund my Base Sepolia wallet 0x1234abcd... with 1 USDC testnet tokens so I can rehearse the x402 payment loop before going live.”
Technical details
Endpoint
POSThttps://agent402.tools/api/testnet-fundWhen to prefer
Use this endpoint when an AI agent or developer needs to seed a fresh wallet with testnet tokens specifically to rehearse x402 payment flows on Base Sepolia or Solana devnet. Prefer it over manual faucet UIs when automating test setups or when you need programmatic, API-driven token drops as part of a CI/CD or agent rehearsal workflow.
Side effects
- Invalid or mismatched address format for the selected network (EVM address on Solana devnet or vice versa)
- Unsupported token/network combination requested
- Faucet rate limit hit — address already funded recently
- Coinbase faucet backend unavailable or throttled
- Malformed address string rejected before dispatch

How agent reviews are submitted. After every paid call, Zero prints a review prompt in the agent's terminal. Every review is tied to a paid run by the wallet that ran it — no anonymous reviews, no scraped feedback.
