Image EXIF
POST /api/image-exifExtract EXIF metadata from an image (camera make/model, timestamps, exposure, orientation, GPS). Send POST /api/image-exif with no required fields (2 optional) and pay $0.003 per call over x402 or MPP (there is no free tier). It returns a JSON object with format, width, height, bytes, hasExif and 2 more.
Send a public image URL or a base64 image; JPEG, PNG (eXIf chunk), and TIFF carry EXIF. Stripped images return an empty exif object, not an error.
Parameters
| Name | Type | Required | Description |
|---|---|---|---|
url | string | no | public http(s) image URL (fetched server-side, 5MB cap) |
image | string | no | alternative: base64 image, optionally a data: URL |
Example request
curl -i -X POST https://agent402.tools/api/image-exif \
-H "Content-Type: application/json" \
-d '{"url":"https://agent402.tools/fixtures/sample-photo.jpg"}'
Without payment this returns HTTP 402 Payment Required with the exact price for image-exif; any x402 v2 or MPP client pays it and retries.

The hosted connector at https://agent402.tools/mcp needs a payment for image-exif; the stdio package pays it from a wallet or from AGENT402_CREDITS_KEY. Local install: npx -y agent402-mcp.
Errors and behavior
- Every field is optional. An input the tool rejects returns an HTTP 4xx whose body carries
error,tool,expected,requiredandexample. - A paid call that ends in any status of 400 or above is not charged over x402, MPP or a prepaid credits key: settlement is cancelled when the tool fails. The exception is a Tempo push credential, a transfer the buyer sent before the call: it settles before the tool runs, so if the tool then fails the payment is recorded as a refund owed to the paying wallet.
- Wallet-only: this tool reaches the network or stored state, so it has no proof-of-work tier. A prepaid card-credits key issued earlier (
Authorization: Bearer a402_...) also pays it. - A
GETorHEADto /api/image-exif returns the same 402 quote, so the price can be read without a body. - An
Idempotency-Keyheader makes a retried paid call replay the first 200 instead of charging again (an answer larger than 1 MB is not replayed).
