How this service works
x402 pay-per-call. Payments are per request in USDC and are final. No refunds on-chain. Service is provided as-is and may change or stop without notice. Informational data only, not financial, investment, legal, or tax advice. Metrics such as net transfer volume estimates and wallet clusters are algorithmic estimates from public blockchain data and may be wrong or delayed. Provided as-is with no warranty. Methodology: https://crypto-data-api-zo95.onrender.com/methodology.
Output
Returns a JSON object with the estimated USD cost of a same-chain USDC transfer on the source chain, the total estimated USD cost of a cross-chain USDC transfer via CCTP Standard, a list of pipeline data freshness checks (including whether ingested data lag is under 300 seconds), the source chain, a UTC timestamp of when the data was generated, and a disclaimer noting the data is informational only.
Example use cases
Cheapest chain routing for USDC payments
“I need to pay someone in USDC — what's the cheapest option, sending it on Base directly or bridging from Base to Ethereum via CCTP? Give me the current cost estimates.”
Cross-chain DeFi cost analysis
“I'm moving funds from Optimism to Arbitrum in USDC. What's the estimated total cost of that cross-chain transfer via CCTP right now?”
Same-chain Ethereum transfer cost check
“Before I send USDC on Ethereum mainnet, can you tell me what the current estimated transfer cost is on-chain in USD?”
Technical details
Endpoint
GEThttps://crypto-data-api-zo95.onrender.com/v1/stablecoin/transfer-cost?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a quick, pay-per-call USD cost estimate for USDC transfers — either same-chain or cross-chain via CCTP — across Ethereum, Base, Optimism, and Arbitrum. It is ideal for agents that need to route stablecoin payments optimally or present fee transparency to users before executing transfers. Prefer this over manual gas estimation tools when you need a unified cost figure in USD rather than raw gas units.
Side effects
- Missing required 'from' query parameter returns a validation error
- Unsupported chain value (not ethereum/base/optimism/arbitrum) returns an enum validation error
- Data pipeline freshness check fails if ingested data lag exceeds 300 seconds
- Service may be unavailable without notice as it is hosted on Render's free/hobby tier
- Payment failure or x402 authentication issue prevents access to the endpoint
