One endpoint.
Your agent pays per call.

MeshPilot is an endpoint, not an app. A request returns a price; your agent pays it in USDC on Solana and gets a production-ready GLB back. Then it can iterate, rig, and build whole sets, autonomously.

01See the price

Call it with nothing. It tells you everything.

An unpaid request answers 402with exactly what to pay, and exactly how - USDC on Solana, straight from the agent’s wallet. A GET on the same endpoint returns the full, self-describing API guide.

the 402, verbatim

curl -i -X POST https://meshpilot.cc/api/generate \
  -H "Content-Type: application/json" \
  -d '{"prompt":"a battle-worn sci-fi helmet","texture":true}'

# HTTP/1.1 402 Payment Required
# { "x402Version": 1, "accepts": [{
#     "network": "solana:5eykt4Us…",   // USDC on Solana
#     "maxAmountRequired": "200000",   // $0.20 (6 decimals)

# }]}

02Pay it

A few lines, straight from the wallet.

USDC on Solana

// Solana: build the partially-signed USDC transfer from the
// 402's requirements, resend with the X-Payment header.
import {
  createSolanaPaymentPayload, solanaKeyToBytes, solanaPublicKey,
  parsePaymentRequired, extractPaymentDetails,
} from "@blockrun/llm";

const r1 = await fetch(URL, { method: "POST", body });     // -> 402
const d = extractPaymentDetails(
  parsePaymentRequired(r1.headers.get("x-payment-required")), "solana");
const header = await createSolanaPaymentPayload(
  await solanaKeyToBytes(KEY), await solanaPublicKey(KEY),
  d.recipient, d.amount, d.extra.feePayer);
const r2 = await fetch(URL, { method: "POST", body,
  headers: { "X-Payment": header } });                     // -> model

Payment settles up front and is refunded automatically if generation fails - your agent is never charged for a model it didn’t get.

03What the endpoint does

Not just generation.

POST /api/generate

Text or image to 3D

Prompt or reference image in, textured GLB out. Tune faces (1k-100k tris), detail, texture on/off, and stamp your license into the file's metadata.

{ "async": true }

Async jobs

Returns a job_id in seconds; poll /api/job/:id until done. Use it for high-detail textured models so nothing times out.

{ "edit", "from_ref" }

Iterate like a chat

Send back the ref from any response with an edit (“make it rusty”) to keep refining the same model. No session to manage.

POST /api/plan

Whole sets

Decomposes “a robot” into head, torso, arms, legs with one cohesive style - each part generated as its own model. Swappable kits.

POST /api/rig

Auto-rigging

Any GLB in, rigged GLB out - skeleton plus skinning weights, ready to animate in-engine.

always on

Model Safeguard

Reference vision-vetted before GPU time; finished mesh swept for stray geometry. Reported per call in the safeguard field.

$0.20 a model. No subscription.
