Avasis Tip Hub – All Topics (Solana + Base + Ethereum)
x402
Avasis Tip Hub – All Topics (Solana + Base + Ethereum) is a paid API for AI agents from agents.avasis.ai, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-31).
Returns a single aggregated response containing all live blockchain tip/fee data: Solana slot/height, Solana priority-fee percentiles, on-chain SOL/USD price, Base gas metrics, and Ethereum gas metrics, each with sequence number, observation timestamp, and age.

How this service works
One answer with every tip topic (Solana slot/height, Solana priority-fee percentiles, on-chain SOL/USD, Base gas and Ethereum gas), each with its seq, observedAt and age. Served from the shared hub: each topic refreshes on its own cadence (1-4 s) while anyone is polling. Prepaid meter price $0.0006/call.
Output
A JSON object with a 'topics' map containing entries for 'base-gas', 'ethereum-gas', 'solana-slot', 'solana-priority-fee', and 'sol-usd'. Each entry includes a sequence number (seq), the topic name, ageMs (milliseconds since last update), and a data payload with chain-specific fields: for Base/Ethereum gas topics this includes gwei breakdowns (baseFee, gasPrice, maxPriorityFee, suggestedMaxFee), blockNumber, and blockAgeSeconds; for Solana topics this includes slot/height and priority-fee percentiles; for SOL/USD this includes the current price.
Example use cases
Pre-transaction fee estimation on Solana
“Before I submit this Solana transaction, what priority fee percentiles are live right now, and what's the current slot height?”
Multi-chain DeFi bot gas optimization
“I need the current Base baseFee and suggestedMaxFee alongside Ethereum gas prices so my bot can pick the cheapest chain to execute on right now.”
Live SOL/USD price check for portfolio valuation
“What's the current on-chain SOL/USD price from the Avasis tip hub, and how fresh is the data?”
Technical details
Endpoint
GEThttps://agents.avasis.ai/v1/tip/all?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need fee/gas data from multiple chains (Solana, Base, Ethereum) in a single HTTP call rather than querying each chain separately. Ideal for agents that need to compare chains before routing a transaction, monitor gas trends across ecosystems, or need SOL/USD price alongside fee data. The shared-hub design means data is always near-fresh (1-4s cadence) without the agent having to manage multiple polling connections.
Side effects
- Payment failure (x402 prepaid meter exhausted or invalid payment) — returns HTTP 402
- Upstream data temporarily stale — ageMs may be elevated if a chain's data source is lagging
- Rate limiting if polled faster than refresh cadence (1-4s per topic)
- Network timeout if the hub is temporarily unreachable
- Empty or partial topics object if one chain's feed is down
