Quotient API

Quotient API Skill

Use this skill when an agent needs Quotient market intelligence and must execute x402 payment flows correctly.

Base URL

• QUOTIENT_BASE_URL: https://q-api.quotient.social
• Use this single origin for runtime requests and discovery docs (/openapi.json, /api/public/pricing, /llms.txt, /skill/*).

Access Model

• Use x402 or API key for monetized requests.
• Prefer Bankr wallet tooling when available.
• Support vanilla SIWE/SIWX x402 clients as a first-class fallback.
• Include x-quotient-api-key when available; runtime requests can be authorized via either x402 payment handling or API key auth.
• If using Bankr signing (/agent/sign), provide a Bankr API key via X-API-Key with Agent API access enabled and signing permissions (not read-only).

Getting a Quotient API Key

• Sign up (or log in) at https://dev.quotient.social.
• Account creation supports:
  • email login
  • Google login
• New accounts include free credits, so users can try the API before paying.
• After signup/login, create or copy a Quotient API key from the Quotient account settings/developer area.
• Pass the key to the agent via config/secrets as x-quotient-api-key (or equivalent env/secret wiring used by your client).

Operator vs Agent Signup Path

• Preferred: human operator completes signup/login and key creation, then injects the API key into agent config.
• Optional self-serve agent path: if your runtime supports browser automation plus secure secret storage, the agent can perform signup/login at https://dev.quotient.social, generate a key, and store it for later requests.
• If interactive auth (email verification, Google OAuth, CAPTCHA, 2FA, policy prompts) cannot be completed programmatically, fall back to the human-operator path.

x402 API Call Checklist

1. Send request to Quotient gateway without payment headers.
2. If response is 402, parse PAYMENT-REQUIRED.
3. Sign payment and retry with PAYMENT-SIGNATURE.
4. On success, parse PAYMENT-RESPONSE.
5. Apply retry/backoff rules for 429 and transient 5xx.

Required Preflight (Deterministic)

Before the first API call in a session, fetch these discovery endpoints:

• /openapi.json
• /api/public/pricing
• Treat OpenAPI as canonical route and invocation metadata.
• Treat pricing endpoint as supplemental billing/network metadata (assets, chains, credit mapping), and treat runtime 402 challenge data as authoritative.
• Cache pricing metadata and refresh periodically (for example, every 15-60 minutes) or immediately when runtime 402 details differ from cache.

Canonical Endpoints and Discovery

• OpenAPI: /openapi.json
• Pricing discovery endpoint: GET /api/public/pricing
• AI index: /llms.txt

Core Endpoints

• GET /api/v1/markets - covered markets with forecast status
• GET /api/v1/markets/mispriced - markets where Q diverges from market odds
• GET /api/v1/markets/lookup - batch lookup by slugs or condition IDs
• GET /api/v1/markets/{slug}/intelligence - full intelligence on a single market
• GET /api/v1/markets/{slug}/signals - paginated analyst signals for a market
