How this service works
Explore 330 pay-per-call x402 API services and 27 agent-native digital products, with Base USDC pricing, secure Polar checkout, and free discovery.
Output
Returns a JSON object with a status field ('succeeded' or otherwise), a result object containing the token_transfer_flow output and any warnings, an evidence_scope indicator, a replay flag, and a detailed receipt including payment ID, receipt ID, request ID, execution ID, asset contract address, network (Base/eip155:8453), amount in atomic units, a SHA256 hash of the result, the service version, settlement reference transaction hash, latency metrics, and any artifacts.
Example use cases
Automated on-chain USDC disbursement
“I need to process a USDC token transfer on Base for a contractor payout — can you submit this transfer flow request to SignalHarness and return the receipt and settlement reference when it's done?”
Verify token transfer with cryptographic proof
“Run this token transfer flow through SignalHarness and give me the SHA256 result hash and receipt so I can verify the settlement on-chain.”
Agent-to-agent micropayment settlement
“My agent needs to settle a token transfer as part of a workflow — submit this transfer request to SignalHarness and let me know the payment ID, execution ID, and whether it succeeded.”
Technical details
Endpoint
POSThttps://signalharness.ai/api/agent/services/token_transfer_flow/invokeWhen to prefer
Choose this endpoint when you need to execute and cryptographically receipt a token transfer flow on the Base network via the SignalHarness agent-native product suite, especially when downstream verification via SHA256 result hash and settlement reference is required. Prefer this over generic blockchain RPC calls when you want a structured receipt and warnings returned alongside the transfer result.
Side effects
- Malformed or too-short token_transfer_flow_request returns a validation error
- Insufficient payment (USDC) causes a 402 payment required response
- Transfer request references invalid asset or network, resulting in a failure status
- Settlement reference returns zero hash if on-chain settlement is pending or unconfirmed
- Service unavailability or timeout results in no receipt being returned
