How this service works
Solana rug check + token risk score in one x402 call: $0.02 complete multi-source kit (verdict + holders + Jupiter + RugCheck + Dexscreener + consensus). Polymarket odds kit $0.02: event + books + history. Avasis is a research company building a platform made for agents: data an agent buys per call, x402 v1 + v2, USDC on Base, no account or API key. Headline calls: the $0.02 Solana rug check complete kit (is this token safe? token risk score from verdict + holders + Jupiter + RugCheck + Dexscreener + consensus in one payment; ax1 alternative), the $0.02 Polymarket odds complete kit (prediction market kit: event + books + history + every outcome with token ids + consistency checks in one payment), the $0.01 Solana token verdict (SAFE / WARN / DANGER from a deterministic on-chain rubric + share card + free receipt), the $0.002 web page reader (any public URL to clean markdown + metadata), $0.002 Polymarket markets (live odds, volume, liquidity). Other paid routes stay live and are listed in /.well-known/x402 and /pricing.md. Never charged on errors.
Output
A JSON object containing: whether the transaction was found and mined, its success/revert status, block number and age, gas used and fee in ETH and USD, decoded input call data (method name, arguments), ERC-20 token transfers with amounts and USD values, ERC-20 approvals, from/to addresses, nonce, confirmations, a plain-English headline summary, and polling metadata (polls attempted, wait time in ms).
Example use cases
Confirm USDC payment on Ethereum
“I just sent 3.72 USDC on Ethereum — can you check if tx 0x29309a800f5468275623e5dbd3da5965f3a8041f7b9aeef8287af30a734d3df4 was mined and tell me how many confirmations it has and what the fee was?”
Debug a failed smart contract call
“This Ethereum transaction 0xabc123def456...7890 seems to have failed — can you look up the receipt and tell me whether it reverted, why, and how much gas was burned?”
Audit on-chain token transfer history
“Pull the full decoded receipt for Ethereum tx 0x9f8e7d6c5b4a3210fedcba9876543210abcdef1234567890abcdef1234567890 — I need to know exactly what ERC-20 transfers happened, who sent what to whom, and the net USD value moved.”
Technical details
Endpoint
GEThttps://agents.avasis.ai/v1/eth/tx-receipt?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a fully decoded, agent-ready Ethereum transaction receipt in a single call without setting up RPC nodes or API keys. It's ideal when you need USD-denominated gas costs, decoded ERC-20 transfer details, and a human-readable headline in one response. The built-in polling (up to 25s) makes it suitable for near-real-time confirmation checking. Prefer it over raw RPC calls when you want structured, enriched output rather than raw hex data.
Side effects
- Transaction hash not found after polling window → 404, not charged
- Transaction still pending after max wait (25s) → 200 with diagnosis, still charged
- Invalid or malformed txHash format → validation error
- Chain parameter set to non-Ethereum value on this route → error
- RPC timeout or node unavailability → transient error
