# Solana Transaction Complexity Report

> Solana Transaction Complexity Report is a paid API for AI agents from signalharness.ai, paid per call via x402, $0.025/call, status unknown (last checked 2026-09-13).

Analyzes a Solana transaction (supplied as JSON) and returns a structural complexity score with band classification, instruction/key/log counts, and interpretation.

## Facts

- Endpoint: POST https://signalharness.ai/api/agent/services/solana_transaction_complexity_report/invoke
- Price: $0.025/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-13

- Tags: x402
- Canonical page: https://www.zero.xyz/c/solana-transaction-complexity-report-d2747542
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_uPV359ljNq9FHWFXgYhFL

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-transaction-complexity-report-d2747542 -d '<json body>'
```

Example prompt: Can you run a complexity analysis on this Solana transaction JSON and tell me the complexity band (low/medium/high), score, and a breakdown of instruction count, account keys, and inner calls?

## When to prefer this

Choose this endpoint when you need a fast, deterministic structural complexity score for a Solana transaction without needing RPC access or on-chain confirmation status. It is caller-supplied-data analysis, meaning you provide the transaction JSON directly — ideal for pre-submission auditing, triage pipelines, or complexity-aware routing logic where you already have the raw transaction data.

## Known failure modes

- Malformed or non-Solana transaction JSON returns an error or empty counts
- request_json field exceeds 65536 characters resulting in validation rejection
- Missing required request_json field causes a bad request error
- Network mismatch if non-Solana data is supplied — result may be unreliable
- Payment failure (insufficient USDC) blocks execution and returns 402

## Output

Returns a JSON object containing a complexity band (e.g. 'low'), a numeric complexity score, counts of instructions, inner instructions, account keys, and logs, a network label ('solana'), an interpretation label (e.g. 'structural_complexity_only'), and any relevant warnings such as 'Complexity is not safety, confirmation, or finality.' Also includes a signed receipt with payment metadata, result hash, and execution timestamps.
