# Ambolt Solana Transaction Lookup

> Ambolt Solana Transaction Lookup is a paid API for AI agents from api.ambolt.dev, paid per call via x402, $0.005/call, status unknown (last checked 2026-10-11).

Fetches on-chain details for a Solana transaction by signature, returning slot, block time, signers, fee, compute units, SOL balance changes, and token changes.

## Facts

- Endpoint: GET https://api.ambolt.dev/v1/solana-transaction?utm_source=zero.xyz
- Price: $0.005/call
- Payment: x402
- Status: unknown
- Last checked: 2026-10-11

- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_ETPWFxPrzUgLY_DGPBjPP

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 ambolt-solana-transaction-lookup-8c1a8cf2
```

Example prompt: Can you look up the Solana transaction with signature 2sR4wGisrFXKoNBfcwCSxbgqfZwXZBk1eWDRW7CmBT9EvYoLiMoWCNzPEmLmaHTBm5pNmgFBLmWfBjd1PzSamPTv and tell me which accounts gained or lost SOL, which tokens moved, and whether it succeeded?

## When to prefer this

Use this endpoint when you need authoritative on-chain facts about a specific Solana transaction — particularly SOL and SPL token balance changes, fee details, and program invocations — without running your own RPC node. At $0.005 per call it is cost-effective for spot lookups and agent workflows that need to verify payments, audit trades, or reconcile wallet activity on Solana mainnet.

## Known failure modes

- Invalid or malformed base58 signature returns a validation error
- Transaction not found on mainnet returns found:false
- RPC node unavailability may cause timeouts
- Unconfirmed or very recent transactions may not be found yet
- Payment failure (x402) if USDC balance is insufficient

## How this service works

Pay-per-call data tools for developers and AI agents: company registers, documents, tenders, rates and on-chain facts as MCP tools, x402 endpoints and Apify Actors.

## Output

A JSON object containing: found/success flags, slot number, block time, checked-at timestamp, fee payer address, signer addresses, invoked program names, fee in lamports, compute units consumed, per-account SOL delta changes (deltaLamports), per-token changes (mint, owner, delta, decimals), and any error message. Source is Solana mainnet RPC confirmed state.
