A well-calibrated market resolves Yes about as often as its price; gaps show where prices ran rich or cheap. Kalshi prices are the midpoint of the best bid and ask, or the last trade; Polymarket prices are the last recorded probability of the day, from archived history. ## OpenAPI ````yaml /openapi.yaml get /v1/insights/calibration openapi: 3.1.0 info: title: Routeur Graph API version: '2026-09-15' summary: >- Proven relations between Kalshi and Polymarket contracts, with the history and signals built on them. description: > Routeur reads every open market on Kalshi and global Polymarket, and proves which ones imply, exclude or equal each other from each venue's structured contract terms and exact arithmetic. No relation is inferred from prose, and ambiguous or conflicting evidence is withheld. ## Authentication Send your key in the `X-API-Key` header, or as `Authorization: Bearer `. Keys look like `rk_live_<12-character id>_<43-character secret>` and are shown once when issued. Keep them server-side. ## Rate limits Every key has a per-minute limit and a per-day quota set by its tier: | Tier | Requests per minute | Requests per day | |---|---|---| | free | 30 | 2,000 | | trader | 120 | 50,000 | | pro | 600 | 500,000 | | institutional | 3,000 | 10,000,000 | Responses carry `X-RateLimit-Limit`, `X-RateLimit-Remaining` and `X-RateLimit-Reset` (Unix seconds) for the minute window, and `X-Daily-Quota-Limit` and `X-Daily-Quota-Remaining` for the day (UTC). A request over either limit returns `429` with `Retry-After` in seconds. ## Conventions - Money and prices are decimal strings in USD (for example `"0.4100"`), never floats. Prices are per contract that pays $1. - Times are RFC 3339 in UTC. - Successful responses wrap results in `data`. Graph-derived responses also name the `graph_run` they were read from; runs finish hourly. - Paginated lists return `next_cursor` when more results exist. Pass it back as `cursor` unchanged; cursors are opaque. - Unknown or repeated query parameters are rejected with `400`, so typos never silently widen a query. ## Errors Errors return a JSON body `{"error": {"code": "...", "message": "..."}}`. Branch on `code`; messages may change. | Status | Code | Meaning | |---|---|---| | 400 | `invalid_parameter` | A query parameter is unknown, repeated or out of range. | | 400 | `invalid_market` | The venue is not `kalshi` or `polymarket`, or the market id is malformed. | | 401 | `api_key_required` | No key was sent. | | 401 | `invalid_api_key` | The key is malformed or unknown. | | 401 | `api_key_revoked` | The key was revoked. | | 404 | `market_not_found` | The market is not in the latest graph. | | 404 | `not_found` | No such endpoint. | | 429 | `rate_limited` | The per-minute limit was exceeded. | | 429 | `daily_quota_exceeded` | The daily quota is used up. | | 503 | `graph_unavailable` | No graph run has finished yet. | | 504 | `timeout` | The request took longer than 15 seconds. | | 500 | `internal` | Something failed on our side. | ## Webhooks Mispricing alerts are delivered as signed `POST` requests; see the `webhooks` section. Each request carries `Routeur-Signature: t=,v1=`, where `v1` is HMAC-SHA256 of `.` keyed by your subscription's signing secret. Reject requests whose signature does not match or whose `t` is more than five minutes old, and respond `2xx` within 10 seconds. `Routeur-Delivery` identifies the delivery and stays the same across retries, so use it to ignore duplicates. Any response other than `2xx` or `410`, or no response, is retried with exponential backoff from 30 seconds for up to 8 attempts; responding `410 Gone` disables the subscription. Endpoints must be HTTPS on a public address, and redirects are not followed. contact: name: Routeur url: https://routeur.app servers: - url: https://api.routeur.app security: - apiKey: [] - bearer: [] tags: - name: Events description: Real-world events across both venues, the way people browse them. - name: Graph description: Markets and the relations proven between them. - name: History description: Recorded quotes and trades. - name: Signals description: Mispricing leads and unusual trading derived from the graph and history. - name: Service description: Service status and this document. paths: /v1/insights/calibration: get: tags: - Signals summary: How prices resolved description: > For settled markets, how often markets priced in each 10-cent band a number of days before close resolved Yes.
