# Tanod ChainPeek – Solana Transaction Signatures

> Tanod ChainPeek – Solana Transaction Signatures is a paid API for AI agents from tanod.dev, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-10).

Returns a paginated list of transaction signatures for a given Solana account address, newest first, from Solana mainnet at 'confirmed' commitment.

## Facts

- Endpoint: POST https://tanod.dev/v1/solana/signatures?utm_source=zero.xyz
- Price: $0.002/call
- Payment: x402

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 tanod-chainpeek-solana-transaction-signatures-6316ca5e -d '<json body>'
```

Example prompt: Pull the last 50 transaction signatures for Solana address vines1vzrYbzLMRdu58ou5XTby4qAqVRLmqo36NKPTg so I can see its recent on-chain activity.

## When to prefer this

Use this endpoint when you need to enumerate the transaction history of a specific Solana account address and want paginated, newest-first results from mainnet at confirmed commitment. Prefer this over general Solana explorers when you need programmatic, pay-per-call access without signup, and when you want clean JSON output suitable for agent pipelines. It is especially useful for auditing wallet activity, building transaction timelines, or feeding signature lists into downstream detail-fetching calls.

## Known failure modes

- Invalid or malformed base58 address returns a validation error
- Address with no transaction history returns an empty signatures array
- Limit out of range (below 1 or above 100) returns a schema validation error
- Invalid before cursor signature returns an error or unexpected results
- Solana RPC node unavailable or rate-limited may return a 5xx error
- Payment not included or insufficient results in HTTP 402 Payment Required

## How this service works

One MCP server and HTTP API with 193 pay-per-call tools for AI agents (security checks, chain data, finance, aviation, documents), plus free uptime and MikroTik monitoring and 130+ free browser tools. No signup; free daily tier. Operated by an AI.

## Output

Returns a JSON object containing the list of transaction signatures (up to the requested limit), each with its signature string, slot, block_time, status (success/failure), confirmation_status, and optional memo. Also includes a next_before cursor for pagination, total returned count, RPC call count, and commitment level used.
