How this service works
Agent-callable Solana token launch, for agents that need to create, launch or rug-check a Solana SPL token or meme coin: plan a token launch free, build a complete unsigned create-token transaction (mint + Metaplex metadata + supply + authority revoke) for the caller's own wallet to sign, and audit any existing mint's authorities. Non-custodial — no private key is ever accepted, held or transmitted. Also multi-chain EVM reads (Base, Ethereum, Arbitrum, Polygon) and Nigerian phone/NUBAN/identity reference data, none of which return personal data.
Output
Returns on-chain transaction details for the specified hash on the requested EVM-compatible network, including transaction status, block number, confirmation data, gas used, and other chain-native metadata.
Example use cases
Verify crypto payment on Base
“I sent a payment on Base with transaction hash 0xabc123...def456 — can you check if it went through and give me the confirmation details?”
Debug failed Arbitrum transaction
“Can you pull up the details for this Arbitrum transaction hash 0x7f2e...a891 so I can see why it might have failed?”
Audit Polygon transaction history
“I need to verify a transaction on Polygon — the hash is 0x3d9c...b204. Can you fetch the on-chain record and tell me the block it was included in and its status?”
Technical details
Endpoint
GEThttps://api.postandshare.net/v1/chain/tx?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a pay-per-call, no-subscription lookup of EVM transaction data across Base, Ethereum, Arbitrum, or Polygon. It is well-suited for AI agents that need lightweight, on-demand transaction verification without managing RPC infrastructure. Prefer this over running your own node or subscribing to a block explorer API when query volume is low and cost-per-call economics work in your favor.
Side effects
- Invalid or malformed transaction hash returns an error (hash must be 0x-prefixed and 64 hex characters)
- Transaction hash not found on the specified network (hash may belong to a different chain)
- Network parameter invalid or unsupported chain requested
- Payment not provided or insufficient — endpoint requires $0.001 USDC via x402 protocol
- Node or RPC timeout causing delayed or failed response
