Add Suede AI - rights-aware music & video generation (x402, Base)

[JasonColapietro]

Add Suede AI

What: Adds Suede AI to Example Applications > API Examples — a live, agent-payable creative IP service. Autonomous agents pay USDC on Base for music and short-video generation, plus 20+ supporting music-production and rights-lookup skills.

Why: Suede AI is one of the few media-generation endpoints in the x402 ecosystem, and the only one wired to on-chain IP provenance. Every output is fingerprinted and eligible for attestation through the Suede Registry on Base, so agents producing creative work get a portable rights anchor on top of the payment itself. Useful for any agent that needs licensed-by-default audio/video as part of its workflow.

Endpoints (selected from 22 live paid routes; 24 products in catalog):

• POST /create-music — $0.20 USDC per track (200000 atomic units)
• POST /agent/video — $1.50 USDC per clip (1500000 atomic units)
• POST /agent/generate — $0.20 USDC, programmatic media generation through the IP stack

Full price list and routes: https://app.suedeai.ai/api/v1/catalog (canonical source — values mirror the x402 challenges).

Live verification:

• x402 discovery: https://app.suedeai.ai/.well-known/x402.json (HTTP 200, 22 routes, valid challenge schema)
• Agent card (ERC-8004): https://app.suedeai.ai/.well-known/agent-card.json (HTTP 200)
• Agentic commerce catalog: https://app.suedeai.ai/api/v1/catalog (HTTP 200, 24 products)
• Network: Base mainnet (eip155:8453)
• Asset: USDC (0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913)
• Recipient (uniform across x402 + catalog): 0xb5a05466712fd5bcdf2883f43cC6B1799428032d

Curl repro:

curl -i -X POST https://app.suedeai.ai/create-music \
  -H "Content-Type: application/json" \
  -d '{"prompt":"ambient lofi","durationSeconds":30}'
# -> HTTP/1.1 402 Payment Required + valid x402 challenge

Refreshed the API Examples entry: catalog has grown from 17 to 24 paid skills (stems-pro, MIDI, mastering, lyric sync, vocal isolation, rights lookup, prompt analysis, guitar rig analysis/oracle/roast added to the original music + video set). Added links to the agentic-commerce manifest and /api/v1/catalog index alongside the existing x402 + agent-card surfaces. Marking as draft for re-review.

Ran a no-payment external pass against the public Suede AI x402 surfaces. I did not send payment headers, sign requests, or attempt paid calls.

Repro:

curl -i https://app.suedeai.ai/.well-known/x402.json
curl -i https://app.suedeai.ai/api/v1/catalog
curl -i -X POST https://app.suedeai.ai/create-music \
  -H 'Origin: https://app.suedeai.ai' \
  -H 'Content-Type: application/json' \
  -d '{"prompt":"ambient lofi","durationSeconds":30}'
curl -i -X OPTIONS https://app.suedeai.ai/create-music \
  -H 'Origin: https://chatgpt.com' \
  -H 'Access-Control-Request-Method: POST' \
  -H 'Access-Control-Request-Headers: content-type,x-payment'

What looks good:

• /.well-known/x402.json and /.well-known/agent-card.json are live.
• Sampled paid routes (/create-music, /agent/video, /agent/generate) return structured 402 before execution, with Base USDC, canonical resource URLs, Payment-Required, Cache-Control: no-store, and browser-readable payment headers for https://app.suedeai.ai.
• /api/v1/catalog is live and exposes the 24-product catalog plus seller metadata.

Patch notes before merge:

• P1: listing/manifest/catalog price and payee drift need one source of truth. The PR text still says $0.75 for music and $5.00 for video, while live x402 challenges show 200000 and 1500000 USDC units. Also, the x402 manifest/challenges use payTo 0xb5a05466712fd5bcdf2883f43cC6B1799428032d, while /api/v1/catalog payment metadata lists receiver 0x0e3557e4f662f9bca497611b60c95330de747a7d.
• P2: x402-surface-check@latest could not auto-probe the manifest because the JSON is keyed as POST /route entries rather than a recognized manifest/OpenAPI/resource list shape. The routes work manually, but generic crawlers may miss them.
• P2: browser preflight from https://chatgpt.com returns 400 while still including useful CORS allow headers. If cross-origin agent clients are intended, a clean 204/200 preflight would remove ambiguity.
• P3: https://app.suedeai.ai/.well-known/agent.json is 404 while agent-card.json is live. That may be intentional for ERC-8004, but adding an alias or documenting the distinction would help generic agent crawlers.

Quick check-in — happy to provide any additional info that would help with review. The 17-endpoint surface is live and stable: https://app.suedeai.ai/.well-known/x402.json, with curl repro below if useful for verification:

curl -i -X POST https://app.suedeai.ai/create-music \
  -H 'Content-Type: application/json' \
  -d '{"prompt":"ambient lofi"}'

Returns a clean 402 challenge (USDC on Base, EIP-3009). Thanks for maintaining the list.

Thanks for the pass — body updated to reflect the current 22-route surface and $0.20 / $1.50 pricing, with https://app.suedeai.ai/api/v1/catalog pinned as the canonical price source.

For the record: the catalog receiver matches the x402 payTo (0xb5a05466712fd5bcdf2883f43cC6B1799428032d) uniformly across all 22 paid routes — there is no separate 0x0e35…7a7d address in either surface. The price drift between the original PR text and the live challenges was real and is the fix that went into the updated body.
