# SameDayDesk Solana Transaction Receipt

> SameDayDesk Solana Transaction Receipt is a paid API for AI agents from agents.samedaydesk.com, paid per call via x402, $0.002/call, status unknown (last checked 2026-09-15).

Looks up and verifies a finalized Solana mainnet transaction, returning its status, USDC token owner deltas, and payment verification details.

## Facts

- Endpoint: GET https://agents.samedaydesk.com/chain/solana-transaction-receipt
- Price: $0.002/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-15
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/samedaydesk-solana-transaction-receipt-360e3270
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_fWOa0shU-0dMJqphvX-VC

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability samedaydesk-solana-transaction-receipt-360e3270
```

Example prompt: Can you pull the Solana mainnet transaction receipt for signature 3CjY...GNZn and confirm whether the canonical USDC was actually transferred and the transaction is finalized?

## When to prefer this

Use this endpoint when you need deterministic, bounded on-chain proof that a specific Solana transaction occurred and USDC changed hands — particularly in agent-to-agent payment flows using x402 or MPP where you need settlement evidence without signing or broadcasting anything. Prefer this over generic Solana explorers when you need structured token-delta data and payment verification in a machine-readable format with explicit boundary attestation.

## Known failure modes

- Transaction signature not found on Solana mainnet — receipt.found returns false
- Transaction exists but not yet finalized — finalized returns false
- Invalid or malformed transaction signature format returns an error
- Network timeout or RPC unavailability may delay response
- Mint address provided does not match canonical USDC — deltas may be zero or misattributed

## How this service works

Deterministic agent APIs for web and company intelligence, repository security, agent-work economics, machine-service discoverability, payment preflight and settlement proof, wallet context, and Morpho decision evidence. Pay per call through Base x402 or native MPP, with a Circle Gateway Nanopayments path for gasless batched USDC.

## Output

Returns a JSON object with the transaction's slot, status (success/failure), block time, fee in lamports, finalization flag, USDC owner deltas (who gained/lost how much canonical USDC), total token owner delta count, a verification block indicating whether the payment matched a requested amount/recipient, a 'decision' field (found/not-found), and a boundary attestation confirming no wallet signing or private ledger access occurred.
