# A test delivery

> Sent when a test ping is requested for a subscription, through the same signed delivery path as real alerts.



## OpenAPI

````yaml /openapi.yaml webhook ping
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
    <key>`.

    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=<unix seconds>,v1=<hex>`, where `v1` is

    HMAC-SHA256 of `<t>.<raw body>` 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.
