API reference

GET /chains · GET /status?id=0x{64 hex} · GET /quote?originChainId=8453&destinationChainId=42161&originCurrency=0x0000000000000000000000000000000000000000&destinationCurrency=0x0000000000000000000000000000000000000000&amount=1000000000000000&user={your EVM address}. Quotes are estimates only, with executable:false. Base-unit amounts are decimal strings. Initial quote networks: 1,10,56,137,4663,8453,42161,43114,59144; provider route support still applies. Chain 4663 is mainnet, not testnet 46630. Shared quotas: 10/minute and 500/day. No bodies, extra parameters, arbitrary URLs, hooks, fee recipients, permits or execution. No Apiary gateway fee; provider transaction fees are separate. Admin reporting is private. SEPARATE TESTNET BRIDGE: GET https://www.apiary.world/api/relay/testnet for agent instructions. POST /api/relay/testnet/prepare with JSON {id:new UUID,wallet:owner EVM address,amount:integer wei string} returns a proposal and reviewUrl, never sends funds. Native ETH only, fixed Sepolia 11155111 to Base Sepolia 84532, same sender/recipient, 0.0001–0.01 ETH, five-minute quotes. Open https://www.apiary.world/relay/testnet for wallet ownership login, exact review and user wallet approval. POST /api/relay/testnet/status with {requestId} to track public Relay testnet status; source receipt alone is not delivery. Mainnet execution stays disabled. Testnet fees/gas have no real-dollar billing value. All testnet API calls are logged as zero-charge operations in private admin usage.

Integration scope

Independent Relay integration for supported-chain discovery, EVM cross-chain quotes and public status checks. No signing, approvals, calldata or transaction execution. Gateway reads have no Apiary fee; provider route fees and network gas apply only if the user later executes a transfer outside this tool. No extra affiliate fees or sponsorship. Mainnet data is not Robinhood testnet execution. Private administration distinguishes provider usage, earned app fees and manual financial records; no prepaid balance or invoice feed is invented.
