# Solana Inner Instructions Analyzer

> Solana Inner Instructions Analyzer is a paid API for AI agents from signalharness.ai, paid per call via x402, $0.015/call, status unknown (last checked 2026-09-15).

Analyzes Solana transaction inner instructions to extract CPI (Cross-Program Invocation) structure, program inventory, and account references

## Facts

- Endpoint: POST https://signalharness.ai/api/agent/services/solana_inner_instructions_analyze/invoke
- Price: $0.015/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-15
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/solana-inner-instructions-analyzer-542868dc
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_VZhoYBqDMRINEe-rMNnFO

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 solana-inner-instructions-analyzer-542868dc -d '<json body>'
```

Example prompt: Analyze these Solana inner instructions for me and tell me how many CPI calls were made, which programs were invoked, and whether there are any unresolved accounts: {paste inner instructions JSON here}.

## When to prefer this

Choose this endpoint when you have raw Solana inner instruction data and need structured analysis of CPI structure, program inventory, and account resolution without running a full Solana RPC node. Ideal for agents auditing smart contracts, debugging transaction failures, or mapping inter-program call graphs. Prefer this over manual RPC parsing when you need a clean JSON breakdown of the CPI tree in a single pay-per-call request.

## Known failure modes

- Malformed or invalid inner instructions JSON causes parse failure
- Missing inner instructions data (service does not infer them from transaction hash)
- Unresolved accounts remain unresolved if account lookup tables are not supplied
- Input JSON exceeds 65536 character limit
- Network inference may be incorrect if transaction data is ambiguous

## Output

Returns a JSON analysis containing: CPI count (number of cross-program invocations), grouped instruction tree with parent-child relationships, resolved and unresolved account indexes, full program inventory (list of program IDs invoked), the analyzed network name, and any warnings (e.g. missing inner instructions). Also includes a receipt with payment and execution metadata.
