## 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-priority-fee-oracle-873ebc38
```

Example prompt: What priority fee should I use for my Solana transaction right now — give me the p50, p90, and the high/veryHigh suggestions, scoped to the pump.fun program account.

## When to prefer this

Choose this endpoint when you need real-time, percentile-rich Solana priority fee data with actionable tier suggestions (low/medium/high/veryHigh) and the ability to scope fees to specific hot accounts like DeFi programs. Prefer it over generic RPC calls to getRecentPrioritizationFees when you want pre-computed statistics and tier recommendations without writing aggregation logic yourself.

## Known failure modes

- Invalid or malformed account address in ?accounts= returns an error or ignored entry
- More than 10 accounts provided may be rejected or truncated
- Slot data temporarily unavailable if the RPC node is lagging
- Network timeout if Solana mainnet RPC is slow or congested
- Empty or zero fee data during extremely low-activity periods

## How this service works

Recent Solana prioritization fees (micro-lamports/CU) over the last ~150 slots: p25/p50/p75/p90/max, non-zero percentiles and low/medium/high/veryHigh suggestions. Optional ?accounts= to scope to hot accounts.

## Output

Returns a JSON object with the fee unit (micro-lamports per compute unit), full percentile breakdown (p25/p50/p75/p90/max) across the last ~150 slots, non-zero-only percentiles, and four suggested fee tiers: low, medium, high, and veryHigh. Optionally scoped to specific writable accounts (up to 10) for more targeted estimates.
