Real-time crypto data aggregation, DeFi pool analysis, and Twitter management via a pay-per-call x402 agent.
What it does
Web3 Trader is an x402-enabled AI agent hosted on the Questflow platform that provides real-time cryptocurrency data aggregation and analysis. It accepts natural-language prompts via a simple POST interface and can look up token information by contract address, retrieve comprehensive market data, track prices with market metrics, and identify top gaining and losing coins. It also offers DeFi pool analysis across multiple networks, fetches trending coins, NFTs, and categories, and includes Twitter management capabilities such as posting, replying, retweeting, monitoring mentions, and searching tweet content.
The endpoint is live on the Base Sepolia testnet and charges up to 0.50 USDC (maxAmountRequired: 500000 in 6-decimal USDC units) per request using the x402 exact payment scheme. Payments are sent to address 0x5A2f06dC6d03C62Ba9d88B30f9178EF02cb7E7A1 using the USDC contract at 0x036CbD53842c5426634e7929541eC2318f3dCF7e. The maximum request timeout is 1200 seconds, reflecting potentially complex multi-step agent workflows.
The request body is straightforward: a JSON object with a single required "input" string field containing your message to the agent. The response returns a "response" string field. No OpenAPI spec or detailed API documentation is published beyond the x402 challenge's outputSchema. The underlying platform, Questflow, positions itself as an AI agent economy for onchain market scanning and trading.
Capabilities
Use cases
- —Query real-time token prices and market metrics by contract address
- —Identify top gaining and losing cryptocurrencies across markets
- —Analyze DeFi liquidity pools across multiple networks
- —Discover trending coins, NFTs, and categories
- —Automate Twitter posting, replying, and monitoring from an agent workflow
Fit
Best for
- —AI agents needing on-demand crypto market intelligence via natural language
- —Developers building autonomous Web3 trading or research bots
- —Workflows that combine crypto data retrieval with social media actions
Not for
- —Production financial trading requiring guaranteed uptime (this is on a testnet)
- —High-frequency low-latency market data feeds (1200s max timeout suggests agent-style processing)
- —Users who need a fully documented REST API with typed endpoints
Quick start
curl -X POST https://api-dev.intra-tls2.dctx.link/x402/swarm/qrn:swarm:68f7332ab496db62cf748f05 \
-H "Content-Type: application/json" \
-H "X-PAYMENT: <x402_payment_token>" \
-d '{"input": "What are the top 5 trending coins right now?"}'Example
Request
{
"input": "What are the top 5 trending coins right now?"
}Response
{
"response": "Here are the top 5 trending coins: 1. Bitcoin (BTC) — $67,432 (+2.1%), 2. Ethereum (ETH) — $3,812 (+1.8%), 3. Solana (SOL) — $178 (+5.3%), 4. Pepe (PEPE) — $0.0000123 (+12.4%), 5. Dogecoin (DOGE) — $0.164 (+3.7%)"
}Endpoint
Quality
The endpoint is live with a valid x402 402 challenge and a basic outputSchema, but there is no OpenAPI spec, no detailed documentation, no usage examples, and no published rate limits. The response example is inferred from the schema description. The endpoint runs on Base Sepolia (testnet), limiting production readiness.
Warnings
- —No OpenAPI or detailed API documentation available
- —Runs on Base Sepolia testnet — not mainnet; USDC payments are testnet tokens
- —Response example is inferred, not captured from an actual call
- —1200-second max timeout suggests potentially slow agent processing
- —Twitter management capabilities are described but unverifiable from available material
