Supported Chains

HYRE accepts x402 payments on three chains. All chains return identical API data — the only difference is the payment network and gas cost.

Solana (Recommended)

Solana is the primary payment chain for HYRE. Gas fees are sponsored by the HYRE fee payer, so callers pay only the endpoint price in USDC.

Facilitator: Dexter (x402.dexter.cash)
Payment format: Solana transaction with USDC transfer
URL prefix: Root paths (/trenches/new-tokens, /defi/tvl, etc.)

curl -X POST https://mpp.hyreagent.fun/defi/tvl \
  -H "X-PAYMENT: <solana-payment>" \
  -H "Content-Type: application/json" \
  -d '{"chain": "solana"}'

Base

Base (Coinbase L2) offers low gas fees and wide EVM wallet compatibility.

Facilitator: PayAI (facilitator.payai.network)
Payment format: EIP-3009 TransferWithAuthorization (EIP-712 signed)
URL prefix: /base/ prefix

curl -X POST https://mpp.hyreagent.fun/base/defi/tvl \
  -H "X-PAYMENT: <base-payment>" \
  -H "Content-Type: application/json" \
  -d '{"chain": "solana"}'

SKALE

SKALE offers zero gas fees through its sFUEL mechanism. Ideal for cost-sensitive agents and high-frequency queries.

Facilitator: PayAI (facilitator.payai.network)
Payment format: EIP-3009 TransferWithAuthorization (EIP-712 signed)
URL prefix: /skale/ prefix
Chain name: SKALE Europa (chain ID: 1187947933)

curl -X POST https://mpp.hyreagent.fun/skale/defi/tvl \
  -H "X-PAYMENT: <skale-payment>" \
  -H "Content-Type: application/json" \
  -d '{"chain": "solana"}'

SKALE USDC is bridged from Ethereum mainnet via the SKALE Bridge. The USDC contract on SKALE is 0x85889c8c714505E0c94b30fcfcF64fE3Ac8FCb20.
