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.

Example use cases

Verify customer USDC payment on Solana

“A customer says they paid me in USDC on Solana — the signature is 2sR4wGisrFXKoNBfcwCSxbgqfZwXZBk1eWDRW7CmBT9EvYoLiMoWCNzPEmLmaHTBm5pNmgFBLmWfBjd1PzSamPTv. Can you confirm the transaction went through, how much USDC moved, and who sent it?”

Audit DeFi trade execution

“I made a swap on Solana and want to understand exactly what happened. Look up transaction 5xHt3rK9mNpQwJzLqVd7YcBfEuRsTgAmXoPlWvDbCkNiZjMeHyGqFsSJnTbOuIwAr8cV2dP6hEXlKz4mY1RfgWBs and tell me which programs were invoked, how much SOL I paid in fees, and how many compute units were used.”

Reconcile on-chain wallet activity

“Can you pull up all the SOL and token balance changes for Solana transaction 3mQkPr7wXdFbGsNeYhCjTvLuZaKiWoApRqMxOfBtScDgEpNnIrJyHbUlVeSmTz9w2cY5kAj8fXdQzLh1muBVPRoC so I can reconcile it against my records?”

Technical details

Endpoint

GEThttps://api.ambolt.dev/v1/solana-transaction?utm_source=zero.xyz

When to prefer

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.

Side effects

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
