End-to-End Web Proof Workflow
This example demonstrates the complete workflow of generating and verifying a Web Proof using the Web Prover Server.
Step 1: Generate a Web Proof
First, generate a Web Proof for an API call:
curl -X POST https://web-prover.production.vlayer.xyz/api/v2.0 \
-H "Content-Type: application/json" \
-H "Authorization: Bearer ak_ESW9RZSNVBEQ728R8PJBPR80E6EFA9QX" \
-d '{
"url": "https://data-api.binance.vision/api/v3/exchangeInfo?symbol=ETHUSDC",
"headers": []
}'const response = await fetch('https://web-prover.production.vlayer.xyz/api/v2.0', {
method: 'POST',
headers: {
'Content-Type': 'application/json',
'Authorization': 'Bearer ak_ESW9RZSNVBEQ728R8PJBPR80E6EFA9QX'
},
body: JSON.stringify({
url: 'https://data-api.binance.vision/api/v3/exchangeInfo?symbol=ETHUSDC',
headers: []
})
});
const presentation = await response.json();
console.log(JSON.stringify({
...presentation,
data: presentation.data.substring(0, 100) + '...'
}, null, 2));The included credentials are for limited public use. For production use, please contact our team.
Response:
{
"apiVersion": "v2.0",
"data": {
"data": "014000000000...",
"meta": {
"notaryUrl": "https://notary.vlayer.xyz/v0.1.0-alpha.12"
},
"version": "0.1.0-alpha.12"
},
"success": true,
"traceId": "bfbe9da041a6471ba68a9a4115720fdc"
}Step 2: Verify the Web Proof
Now verify the generated Web Proof by sending the json from the /prove response:
curl -X POST https://web-prover.production.vlayer.xyz/api/v2.0/verify \
-H "Content-Type: application/json" \
-H "Authorization: Bearer ak_ESW9RZSNVBEQ728R8PJBPR80E6EFA9QX" \
-d '{
"data": "014000000000000000899cdccd31337c96bb9e519aa438ed73cdb47dda5c80e995ef0a1c04bf6c563730cde41724dafc1391b1b81acc5d989a7f7add8...",
"version": "0.1.0-alpha.12",
"meta": {

}'const response = await fetch('https://web-prover.production.vlayer.xyz/api/v2.0/verify', {
method: 'POST',
headers: {
'Content-Type': 'application/json',
'Authorization': 'Bearer ak_ESW9RZSNVBEQ728R8PJBPR80E6EFA9QX'
},
body: JSON.stringify(presentation)
});
const data = await response.json();
console.log(JSON.stringify(data, null, 2));Response:

"apiVersion": "v2.0",
"data": {
"notaryKeyFingerprint": "a7e62d7f17...",
