What it does

The `/token-alpha` endpoint is part of Otto AI's x402 Agent Swarm, a suite of 30+ AI-powered services accessible via x402 V2 micropayments. This specific endpoint delivers premium token intelligence by combining price metrics, recent news, Twitter sentiment analysis, and futures/derivatives data for any given token symbol. It sits in the Market Intelligence category of the swarm.

The endpoint accepts a GET request with a required `symbol` query parameter (e.g., BTC, ETH, SOL) and costs $0.10 per call, payable in USDC on Base, Polygon, or Solana. Payment follows the x402 V2 protocol: an initial unauthenticated request returns a 402 with a PAYMENT-REQUIRED header containing payment options (EIP-3009 USDC, Permit2 ERC-20, or Solana USDC). After signing and resubmitting with a PAYMENT-SIGNATURE header, the caller receives a 200 response with data plus a signed EIP-712 receipt. Data endpoints like this one also support Sign-In-With-X (SIWX): after one paid call, subsequent requests within a 1-hour window can use a wallet signature for free re-access.

The response follows a standard envelope with `status` ("success" or "failed") and a `data` object containing the aggregated intelligence. The service is designed for programmatic and agent-based access, with machine-readable specs available at `/.well-known/x402` and `/llm.txt`. On-chain reputation feedback is supported via ERC-8004.

Use cases

  • —AI trading agents querying comprehensive token data before executing trades
  • —Portfolio dashboards enriching token holdings with sentiment and derivatives context
  • —Research bots compiling multi-source intelligence on specific cryptocurrencies
  • —Automated alerting systems monitoring token sentiment shifts and futures signals
  • —DeFi agents evaluating tokens before yield farming or swap decisions

Fit

Best for

  • —AI agents needing consolidated token intelligence in a single API call
  • —Programmatic crypto research combining price, news, social, and derivatives data
  • —x402-native workflows that pay per call with USDC on Base, Polygon, or Solana

Not for

  • —High-frequency trading requiring sub-second latency (pay-per-call overhead)
  • —Users who need free or API-key-based access without crypto wallet infrastructure
  • —Historical backtesting with bulk data downloads

Quick start

# 1. Probe for payment challenge
curl https://x402.ottoai.services/token-alpha?symbol=ETH
# Returns 402 with PAYMENT-REQUIRED header (base64-encoded)
# 2. Decode header, sign USDC payment, retry with:
curl -H "PAYMENT-SIGNATURE: <signed_payment>" \
  "https://x402.ottoai.services/token-alpha?symbol=ETH"

Full OpenAPI 3.1 schema is available with clear endpoint descriptions, parameters, and pricing. The endpoint is confirmed live (402 challenge captured). However, the response `data` object schema is generic (untyped object), and no concrete example response is provided in the docs, so the response structure is inferred from the endpoint description.

Warnings

  • —Response data schema is untyped — the OpenAPI spec only defines `data` as a generic object without detailed properties
  • —No concrete example response is available in the documentation; the example_response_json above is inferred
  • —Trading-adjacent endpoint — token intelligence should not be treated as financial advice
