Token Amount to Raw Units
x402
Token Amount to Raw Units is a paid API for AI agents from api.delx.ai, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-15).
Converts a human-readable ERC-20 token amount into its on-chain raw integer representation by scaling by the token's decimal places.

How this service works
Scale human token amounts by decimals into on-chain raw units. Call when building ERC-20 transfer/approve amounts from UI-facing quantities. Returns raw integer string, amount, and decimals used as deterministic JSON for $0.001 USDC via x402 on Base. First-party local math only—no RPC, live market feed, API keys, storage, or mediagen. Advisory only; the caller owns capital, risk, and production controls.
Output
A deterministic JSON response containing the raw integer string (e.g. '1000000' for 1 USDC with 6 decimals), the original human-readable amount, and the decimals value used in the computation. No external calls are made — the result is pure local arithmetic.
Example use cases
ERC-20 transfer amount preparation
“I want to send 50 USDC to a wallet address — USDC has 6 decimals. What's the raw integer amount I need to put in the transfer function?”
ERC-20 approve amount for DeFi protocol
“I'm approving a DeFi contract to spend 1000 DAI on my behalf. DAI has 18 decimals — give me the exact raw integer I need for the approve call.”
Micro-payment amount scaling for x402
“I need to charge exactly 0.001 USDC as a micro-payment using 6 decimals. What's the raw on-chain unit value I should include in the payment transaction?”
Technical details
Endpoint
POSThttps://api.delx.ai/api/v1/x402/token-amount-to-rawWhen to prefer
Use this endpoint when you need a fast, deterministic, local-math conversion from a human-readable token amount to its on-chain raw integer representation — especially when building ERC-20 transfer or approve payloads. Prefer this over manual arithmetic to avoid floating-point errors. No API key, RPC node, or market feed is required.
Side effects
- Missing 'amount' field returns a validation error
- Missing or invalid 'decimals' field (non-integer or negative) returns an error
- Very large decimal values may cause integer overflow edge cases
- Floating-point precision issues if amount has more significant digits than decimals allows
