Tracepay

Use this whenever you need to determine whether a supported stablecoin payment completed, failed, or is delayed — where the money currently is, who owns the next step, and what should happen next. Typical triggers: 'the recipient says the payment never arrived', 'this payout is stuck', 'did this transaction go through?'. Give it a Base transaction hash, Solana signature, Bridge transfer ID, Circle payment ID, or a Base/Solana wallet address (USDC). Trace correlates blockchain and provider evidence into one deterministic normalized state: completed/terminal flags, health, current stage and owner, an evidence-backed diagnosis code with a machine-readable suggested action and retry timing, and a knowledge model separating observed facts from inferences from what Trace cannot see (e.g. beneficiary bank credit — onchain finality never proves the recipient's bank credited funds; unknown never means failed). Public blockchain data works without authentication; provider-connected state requires an API key. If the user has no identifier, ask for a transaction hash, provider payment ID, or supported wallet address. Read-only: this tool never moves funds, retries payments, signs transactions, or guarantees beneficiary receipt — do not use it to send or swap anything. If a payment's state is unresolved, do NOT send a replacement payment; follow the returned warnings and suggested action instead.

Retrieve an existing Trace payment trace by its trace_id (tr_...), including the stage timeline. Read-only. Same normalized representation as trace_payment.

List what Trace supports and can do: assets (USDC), chains with public tracing (Base, Solana), providers requiring connected credentials (Bridge, Circle), and explicit capability flags (read-only; cannot send, retry, or sign). Call this when unsure whether a payment is in scope for trace_payment.
