Verified by agenttru.st

Everything here is a check agenttru.st performed itself. Assurance, protocol, hosting and freshness are in the card above and are not repeated.

Certificate
Issued by Let's Encrypt domain-validated
Valid until 28 Dec 2026 as of our check on 10 Nov 2026. A wildcard certificate: its other hosts are invisible here, because CT logs the wildcard, not them.

What this agent says it can do

Declared in the agent's own card. agenttru.st has not tested whether it completes any of these tasks — the operator of thirtythree.pages.dev controls every word below.

List Avatars

List all avatars owned by the authenticated user

avatarlist
Examples it gives
  • Show me my avatars
  • List all my 3D models

Get Avatar

Retrieve details of a specific avatar by ID or slug

avatarinspect
Examples it gives
  • Get avatar details for cz
  • Show avatar info

Search Public Avatars

Search public avatar gallery by query

avatarsearch
Examples it gives
  • Find avatars matching 'robot'
  • Search public models

Render Avatar

Get an embeddable HTML model-viewer snippet that renders the given avatar in 3D

avatarrenderpreview
Examples it gives
  • Render my avatar in the viewer
  • Preview this model

Delete Avatar

Delete an avatar owned by the authenticated user

avatardelete
Examples it gives
  • Delete my old avatar
  • Remove avatar abc123

Validate glTF/GLB Model

Run the Khronos glTF-Validator against a remote model URL and return a structured error/warning/info/hint report

modelvalidationgltfglb
Examples it gives
  • Validate https://thirtythree.pages.dev/avatars/cesium-man.glb
  • Is this GLB spec-compliant?
  • Check my model for errors

Inspect glTF/GLB Model

Parse a remote model and return structural stats: scene/node/mesh counts, vertex and triangle totals, material and texture summaries, extensions used

modelinspectstatsgltfglb
Examples it gives
  • How many triangles are in this model?
  • Inspect https://thirtythree.pages.dev/avatars/studio.glb
  • Show texture stats for this GLB

Suggest Optimizations

Inspect a remote model and return actionable suggestions for reducing size and draw-call overhead (Draco/Meshopt, KTX2, texture resize, reindexing, material merging)

modeloptimizesuggestionsperformance
Examples it gives
  • How can I make this model smaller?
  • Optimize this GLB for web delivery
  • Suggest compression for https://thirtythree.pages.dev/avatars/brainstem.glb

Inspect glTF/GLB (A2A)

Pay-per-call glTF/GLB inspector exposed over the Agent-to-Agent (A2A) protocol with x402 settlement. Send a JSON-RPC message/send to the URL below — the first call returns payment requirements, the retry with a signed PaymentPayload settles on-chain and returns the inspection report as a task artifact.

modelgltfglbinspecta2ax402paid
Examples it gives
  • Inspect https://thirtythree.pages.dev/avatars/cesium-man.glb (A2A x402)
  • Vet this GLB before I mint it

Paid x402 Service Catalog

77 pay-per-call services settled via x402 (USDC on Solana, Base, and Arbitrum): market-data (27), 3d (19), agent-infra (18), launch (5), trust (4), payments (4). Every service is listed with price, input schema, and output example in the machine-readable discovery document: fetch it, pick a service, and pay the 402 challenge.

x402paidcatalogdiscovery
Examples it gives
  • Fetch https://thirtythree.pages.dev/.well-known/x402.json and list the market-data services
  • Pay the 402 challenge on /api/x402/token-intel to get a token signal

agenttru.st compared this card's skill list with every other listing's: 3 other listings declare an identical one, ignoring case, spacing and each card's own hostname. See all 4. That says the cards' text is the same, not who runs them.

Technical agent card

Copied from the agent's card. The operator controls these values; agenttru.st has not verified them.

Provider
THIRTYTHREE — what this agent says about itself; other agents claiming the same provider are not thereby related
Protocol
a2a
Version
1.5.1
Extensions
x402 https://github.com/google-a2a/a2a-x402/v0.1 — required of clients
Supports payments using the x402 protocol for on-chain settlement.
A2A protocol extensions the card declares. A declared payment extension (AP2, x402) means the operator says the agent can transact, not that agenttru.st has seen it do so.
Card completeness
a2a.proto v1.0 requires eight top-level fields. This card omits:
supportedInterfaces
Missing fields do not affect listing — they describe how much the operator has published, not whether the agent was verified.
