How this service works
Solana priority-fee tip for agents that build transactions: p25/p50/p75/p90/max and non-zero percentiles of getRecentPrioritizationFees over the last ~150 slots, plus low/medium/high/veryHigh micro-lamport suggestions, refreshed every 2 s. Long-poll with ?since=<seq>&wait=25. Prepaid meter price $0.0002/call (packs at /v1/meter); SSE at /v1/stream/tips.
Output
A JSON object containing: a sequence number (seq), the age of the data in milliseconds (ageMs), a staleness flag, the number of slot samples used (~150), priority fee percentiles (p25, p50, p75, p90, max) in micro-lamports per compute unit, and four tiered suggestions (low, medium, high, veryHigh) also in micro-lamports per compute unit. The observedAt timestamp and a changed flag indicate whether the data updated since the last poll.
Example use cases
Set fee before submitting Solana transaction
“Before I send this Solana swap transaction, what's the current recommended priority fee? Give me the medium and high suggestions in micro-lamports per compute unit so I can pick the right one.”
Monitor Solana fee congestion in real time
“Keep watching the Solana priority fee oracle and alert me whenever the p90 percentile jumps above 100,000 micro-lamports — I want to know when the network is getting congested.”
Optimize bot fee strategy dynamically
“My trading bot is about to submit a time-sensitive Solana transaction — fetch the latest priority fee percentiles and use the veryHigh suggestion so it lands in the next block.”
Technical details
Endpoint
GEThttps://agents.avasis.ai/v1/tip/sol-priority-fee?utm_source=zero.xyzWhen to prefer
Use this endpoint when an AI agent is building or submitting Solana transactions and needs a real-time, percentile-based priority fee recommendation rather than a static default. It is preferable to raw RPC calls because it aggregates ~150 slots of data, provides tiered suggestions (low/medium/high/veryHigh), and supports efficient long-polling to detect fee changes. Choose this over generic Solana RPC if you need sub-second fee awareness without managing your own getRecentPrioritizationFees aggregation logic.
Side effects
- Payment required (402) if prepaid meter balance is exhausted
- Stale data (stale:true) if Solana RPC is lagging or endpoint hasn't refreshed within 2s window
- Long-poll timeout if no new data arrives within the specified wait window
- Empty or zero percentiles (p25/p50 may be 0) during low-congestion periods, which is valid but may mislead fee selection
- Rate limiting or connection errors if polling too aggressively without using the long-poll mechanism
