Driving License Verification
kycVerifies a driving licence against the Sarathi (transport department) record: holder name, date of birth, validity dates, licence classes and issuing authority. INPUT FORMAT: send `dl_number` exactly as printed but with no spaces or hyphens (e.g. RJ1420110012345), and `dob` as DD/MM/YYYY (e.g. 15/01/1990). Any other date format is rejected with 400 INVALID_REQUEST. Note that dates in the RESPONSE (dob, valid_from, valid_upto) come back as YYYY-MM-DD; that is the output format only. NOT FOUND: 404 NOT_FOUND means the source has no licence matching that number AND date of birth (usually a wrong date of birth or a typo in the number). It is not a configuration problem and it is NOT charged. Every response, including errors, carries an X-Call-Id header: quote it to support.
POST /gw/v1/driving-license-v1/SLA p95: 2000 ms
Authentication
Pass your key in the X-API-Key header. Use a test_ key against the sandbox and a live_ key in production. Send an optional Idempotency-Key header to safely retry — the same key returns the same response for 24h.
X-API-Key: live_xxxxxxxxxxxx
Request
Endpoint: POST https://apisathi.in/gw/v1/driving-license-v1/
The trailing slash is required. /v1/driving-license-v1/ works; /v1/driving-license-v1 returns 404 Not Found. This applies to every product.
| Field | Type | Required | Constraints |
|---|---|---|---|
| dob | string | required | pattern: ^[0-3][0-9]/[01][0-9]/[12][0-9]{3}$ · Date of birth as on the licence, DD/MM/YYYY (e.g. 15/01/1990). |
| dl_number | string | required | pattern: ^[A-Za-z0-9/]{13,25}$ · DL number as printed, no spaces or hyphens (e.g. RJ1420110012345). |

}Reading a 400
A schema rejection returns INVALID_REQUEST with a details array naming the exact field. Read it before guessing — it gives you the JSON path and what was wrong with it.
{
"error": {
"code": "INVALID_REQUEST",
"message": "Request body failed schema validation",
"details": [
{ "path": "/callback_url",
"message": "unexpected property 'callback_url' — this endpoint does not accept unknown fields" }
]
}
}Most endpoints reject unknown top-level fields outright, so an extra key you added for your own bookkeeping will fail the call. Enum errors list the accepted values, and a missing required field is named with its full path.
Error codes
| Code | HTTP | When |
|---|---|---|
| INVALID_INPUT | 422 | The request was rejected as invalid — either it failed OUR schema validation (malformed input; not charged), or the upstream source rejected the value you sent. NOTE: an identifier that is well-formed but simply has NO RECORD is no longer an error — it returns 200 with `verified: false` and is charged (see the result-code table below). FIX the input before retrying; retrying the same value will fail again. |
| INVALID_API_KEY | 401 | Missing, malformed, or revoked X-API-Key. |
| OUT_OF_SCOPE | 403 | API key is not scoped for this product. |
| INSUFFICIENT_BALANCE | 402 | Wallet balance is below the per-call sale price. Recharge and retry. |
| RATE_LIMITED | 429 | Per-key RPS or RPM limit exceeded. Back off and retry after the Retry-After header. |
| PRODUCT_DEPRECATED | 410 | This API has been retired and is no longer available. Stop calling it — it will not return. Check the catalog for the current equivalent. |
| ROUTER_NO_VENDOR | 503 | No healthy vendor is currently available for this product. Transient — safe to retry after a short backoff. Not charged. |
| VENDOR_AUTH_FAILED | 502 | Upstream vendor rejected our credentials (our config issue). Not charged. |
| VENDOR_ERROR | 502 | A genuine transient upstream error (the source was briefly unavailable). Safe to RETRY after a short backoff. Not charged. NOTE: this is NOT for bad input — invalid values return 422 INVALID_INPUT, not 502. |
| TIMEOUT | 504 | Upstream vendor did not respond within the SLA window. Safe to retry after a short backoff. Not charged. |
| NOT_FOUND | 404 | No licence matches this number and date of birth at the source. Check the DOB (DD/MM/YYYY). Not charged; do not retry unchanged. |
