Determines both the time window covered and the spacing between chart points (`points`). Each period samples the window at a fixed interval, so the number of points is roughly constant (~290–460) regardless of period: | Period | Point interval | Time window | | ---------- | -------------- | ------------------- | | `hour` | 10 seconds | last 1 hour | | `day` | 5 minutes | last 24 hours | | `week` | 30 minutes | last 7 days | | `month` | 2 hours | last 30 days | | `3months` | 6 hours | last 90 days | | `6months` | 12 hours | last 180 days | | `year` | 1 day | last 365 days | | `5years` | 4 days | last 5 years | | `max` | varies | full available history | Point counts are approximate, and `begin_at` / `end_at` are aligned to the interval. For `max`, the interval is derived from the amount of available history (targeting ~400 points), so it varies; for wallet and wallet-set charts the spacing is at least 1 day. schema: type: string minLength: 3 maxLength: 7 default: day enum: - hour - day - week - month - 3months - 6months - year - 5years - max Currency: name: currency in: query required: false description: Denominated currency value of returned prices schema: type: string default: usd enum: - eth - btc - usd - eur - krw - rub - gbp - aud - cad - inr - jpy - nzd - try - zar - cny - chf responses: SingleFungibleChartResponse: description: Resource for the requested fungible chart content: application/json: schema: $ref: '#/components/schemas/Response-13' MalformedParameters: description: Parameters are malformed content: application/json: schema: type: object properties: errors: type: array items: type: object properties: title: type: string description: Error short title example: Parameter is malformed detail: type: string description: Long description of the error example: Some validation errors will be described here UnauthenticatedError: description: Unathenticated request content: application/json: schema: type: object properties: errors: type: array items: type: object properties: title: type: string description: Error short title example: Unauthorized Error detail: type: string description: Long description of the error example: >- The API key is invalid, please, make sure that you are using a valid key NotFoundResponse: description: Resource was not found content: application/json: schema: type: object properties: errors: type: array items: type: object properties: title: type: string description: Error short title example: Resource was not found detail: type: string description: Long description of the error example: Requested resource was not found, try later TooManyRequests: description: Too many requests error content: application/json: schema: type: object properties: errors: type: array items: type: object properties: title: type: string description: Error short title example: Too many requests detail: type: string description: Long description of the error example: Your request had been throttled RetryAfter: description: Service is temporarily unavailable headers: Retry-After: description: > Indicates how long the client should wait before making a follow-up request. schema: type: integer example: 10 description: Number of seconds to wait. content: application/json: schema: type: object properties: errors: type: array items: type: object properties: title: type: string description: Error short title example: Service is temporarily unavailable detail: type: string description: Long description of the error example: Please, retry later (check the Retry-After header) schemas: Response-13: type: object required: - links - data properties: links: $ref: '#/components/schemas/ResponseLinks-13' data: $ref: '#/components/schemas/Container-13' ResponseLinks-13: type: object properties: self: type: string format: url example: >- https://api.zerion.io/v1/fungibles/fda0820a-9cff-40f5-997b-a76b9f9d60e7/charts/day Container-13: type: object required: - type - id properties: type: type: string description: Fungible chart resource type example: fungible_charts id: type: string description: Fungible chart unique identifier example: fda0820a-9cff-40f5-997b-a76b9f9d60e7-week attributes: $ref: '#/components/schemas/Attributes-11' Attributes-11: type: object required: - begin_at - end_at properties: begin_at: type: string description: Begin timestamp of the chart example: '2023-01-18T11:00:00Z' end_at: type: string description: End timestamp of the chart example: '2023-01-25T10:30:00Z' stats: type: object required: - first - min - avg - max - last properties: first: type: number format: double description: First chart value example: 1145.00999 min: type: number format: double description: Minimum value on the chart example: 1133.034 avg: type: number format: double description: Average chart value example: 1689.1110093 max: type: number format: double description: Maximum value on the chart example: 2345.601 last: type: number format: double description: Last chart value example: 1515.34 points: type: array description: Sorted list of chart points items: type: array description: >- Chart point - tuple of two items, the first one is timestamp, the second one is a price in requested currency items: oneOf: - type: integer - type: number minItems: 2 maxItems: 2 example: - 1674039600 - 1145.00999 securitySchemes: APIKeyBasicAuth: type: http scheme: basic description: >- To test endpoints here, paste your API key from the [dashboard](https://dashboard.zerion.io/) into the username field and leave the password empty. ````
